# Changelog

## 2.1.220

- Bug fixes and reliability improvements

## 2.1.219

- Added Claude Opus 5 (`claude-opus-5`), now the default Opus model — 1M context, fast mode at $10/$50 per Mtok
- Added `sandbox.network.strictAllowlist` setting to deny non-allowlisted hosts for sandboxed commands without prompting
- Added `DirectoryAdded` hook that fires after `/add-dir` or the SDK `register_repo_root` control request registers a new working directory mid-session
- Added `mcp_server_errors` to the headless stream-json init event, listing `--mcp-config` entries skipped by config validation; terminal runs print a startup warning
- Added the `workflowSizeGuideline` settings key so the advisory Dynamic workflow size guideline can be set from any settings file; the `/config` row is hidden while one does
- Added nested subagent forwarding in stream-json: subagents spawned at depth-2+ now appear when `--forward-subagent-text` is set, keyed by their spawning Agent `tool_use` id
- Fixed `claude -p` text output dropping the answer already produced when a turn dies on a mid-stream API error
- Added HTTP status and error text to `claude mcp list` and `/mcp` when a server fails to connect, and a warning for MCP config values with hidden leading or trailing whitespace
- Fixed the Fable model row showing "Requires usage credits" for plans that include it, when a stale cache had baked the label in
- Fixed the `/model` picker showing the merged Opus row as plain "Opus" instead of "Opus (1M context)"
- Fixed copy-on-select inside GNU screen printing base64 into the terminal instead of copying the selection
- Fixed Remote Control clients keeping a stale fast-mode status after a model switch, reconnect, or failed org check
- Fixed `CLAUDE_CODE_GIT_BASH_PATH` on Windows exiting or being used as bash when the path isn't a bash/sh binary; it's now ignored with a warning
- Fixed Vim mode: pressing ← on an empty prompt now returns to the agent view from NORMAL mode, not just INSERT
- Fixed screen-reader mode rewriting the entire input line on every keystroke instead of echoing only the typed character
- Improved the "Remote Control is only available via api.anthropic.com" error to name the specific setting that caused it
- Improved `claude --teleport` to show which repo your current checkout points at when it doesn't match the session's repo
- Changed dynamic workflows to default to a medium size guideline (aim for fewer than 15 agents); pick another size or unrestricted with Dynamic workflow size in `/config`
- Changed managed MCP allowlist/denylist `${VAR}` entries to resolve from the startup environment and managed-settings env instead of settings-file env
- Changed the `/model` picker to highlight only the newest model's name, so the highlight marks the new release rather than an arbitrary subset of the list
- Added the current default workflow size to the running-workflow status line, with a pointer to `/config` for changing it
- Removed Opus 4.7 from fast mode; `/fast` now applies to Opus 5 and Opus 4.8
- Updated the claude-api skill to default to Claude Opus 5, with a migration path from Opus 4.8
- Subagents can now spawn nested subagents up to depth 3 by default (was 1); set CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH=1 to disable nesting

## 2.1.218

- Changed `/code-review` to run as a background subagent, so review work no longer fills your conversation and keeps stacked slash commands as its review target
- Added screen-reader announcements of deleted text for word and line deletions (`Option+Delete`, `Ctrl+W`, `Cmd+Backspace`, `Ctrl+U`, `Ctrl+K`) in `--ax-screen-reader` mode
- Fixed Windows paths with `\u`-prefixed segments (like `C:\Users\unicorn`) being corrupted into CJK characters in tool inputs, which made those files inaccessible
- Fixed the left arrow key discarding the conversation with no undo: presses right after editing now ask to confirm, and Esc in the agent view returns to the conversation it backgrounded
- Fixed multi-line paste collapsing into one line with `j` in place of newlines in terminals that encode pasted newlines as Ctrl+J
- Fixed `/context` reporting stale pre-compact token usage after compacting from the message picker
- Fixed `/ultrareview` failing on descriptive arguments like "review my auth changes" — they now run a review of your current branch with the text applied as a note to the findings
- Fixed `/code-review ultra` silently running a local review in non-interactive sessions — it now launches the cloud review
- Fixed gateway spend metering to price Bedrock application-inference-profile ARNs and other config-mapped upstream model IDs at the configured model's rates
- Fixed mojibake when a long IDE selection was truncated mid-emoji, and a case where a tool executor error could be silently dropped
- Fixed an engine teardown race that could start and abandon a phantom turn, and made input pushed after close consistently rejected
- Fixed spurious "[Request interrupted by user]" messages after interrupted tool calls, and an unpaired `tool_use` block left in the transcript when a tool aborted mid-response
- Fixed VoiceOver reading "new line" instead of echoing the typed space at the end of the input in `--ax-screen-reader` mode
- Fixed plugin and settings panels not moving the terminal cursor to the focused row, so screen readers and magnifiers can follow arrow-key navigation
- Fixed crashes (maximum call stack exceeded) when a deeply nested watched directory tree was deleted or moved, and when rendering deeply nested UI trees
- Fixed pull request events occasionally being lost when a session exited immediately after creating or linking a PR
- Fixed the Bedrock setup wizard failing profile verification for assume-role profiles in partitioned AWS regions and on proxy-only networks
- Fixed rare negative or incorrect turn duration measurements after a system clock adjustment by timing turns with a monotonic clock
- Fixed the "N MCP servers need authentication" startup notice over-counting claude.ai connectors that aren't connected in claude.ai
- Fixed prompt history entries being dropped or duplicated when history writes raced or failed
- Fixed a retry loop that re-sent identical doomed requests after a context-overflow error with a large thinking budget; `Ctrl+B` backgrounding now applies the same background-shell caps as other paths
- Fixed agent frontmatter hooks running from untrusted folders: hooks now require the agent file's own folder to have accepted workspace trust
- Fixed fork-session lineage being lost after compaction in headless and SDK sessions
- Fixed a resumed session failing every turn, or crashing on resume, when its history held a malformed delta attachment
- Improved `/ultrareview` error feedback so Claude can correct an invalid argument instead of retrying it unchanged
- Improved auto mode: the dangerous-rm, background-`&`, and suspicious-Windows-path checks no longer open permission dialogs; the auto-mode classifier adjudicates them instead
- Improved sandbox command restrictions for IDE interactions
- Improved trust dialogs to name the repository root the grant covers
- Changed `/deep-research` to start only when invoked manually; Claude no longer launches it on its own
- Changed plan mode with auto to no longer prompt for Bash commands the static analyzer can't prove read-only; the auto-mode classifier judges them instead
- Added an announcement when fast mode changes as a result of switching models via `/config model=<x>` or Remote Control
- Changed server-managed settings so benign feature and cost toggles no longer trigger the settings-approval prompt
- Changed agent markdown files to reject agent names containing `:`, which is reserved for plugin namespacing
- Changed skills with `context: fork` to run in the background by default; opt out per skill with `background: false`
- Added `yes`/`no`/`on`/`off`/`1`/`0` (case-insensitive) as accepted values for skill and plugin frontmatter booleans, alongside `true`/`false`
- Fixed remote sessions continuing to send heartbeats after their worker was replaced, which left long-lived desktop and IDE processes retrying a rejected request every few seconds forever

## 2.1.217

- Added emoji shortcode autocomplete in the prompt input: type `:heart:` to insert ❤️, or `:hea` for suggestions — disable with the `emojiCompletionEnabled` setting
- Added warnings when transcript writes are failing (e.g. disk full) or when session saving is off due to an inherited environment variable, instead of losing transcripts silently
- Fixed a memory leak where truncated MCP tool outputs kept the full untruncated result in memory for the rest of the session
- Fixed Windows auto-update failures that could leave `claude.exe` missing; failed updates now restore the preserved executable automatically
- Fixed background session isolation not canonicalizing symlinked working directories, which could let sessions escape their workspace folder
- Fixed auto-compact never triggering for Claude Opus 4.8 on Bedrock and `/compact` failing once over the limit
- Fixed corporate mTLS, TLS-verify, OAuth scope, and proxy settings being ignored in Claude Desktop sessions
- Fixed screen reader mode's startup announcement being cut off by the first prompt render, and the thinking status row re-rendering every few seconds to update elapsed time and token counts
- Fixed managed settings that set `OTEL_EXPORTER_OTLP_ENDPOINT` not governing all signals — lower-scope signal-specific overrides no longer redirect telemetry away from the managed endpoint
- Fixed `--resume`/`--continue` and `/resume` failing with a TypeError when a transcript has a malformed attachment entry
- Fixed Remote Control sessions not showing a pending permission prompt or dialog to viewers that connected after it appeared
- Fixed background shells sometimes becoming impossible to stop after a session is sent to the background (`/background` or `←`) or when the session exits on a heavily loaded machine, most visible on Windows
- Fixed a `CLAUDE.md` or `SKILL.md` paths frontmatter value with many brace groups OOM-killing or stalling the CLI at startup — brace expansion is now budget-bounded
- Fixed the transcript preview sitting flush against the input area when attaching to a starting background session; it now leaves the same one-line gap as the live layout, so the transcript no longer shifts when the session takes over
- Improved footer PR badge links to be clickable hyperlinks even when terminal support can't be detected (e.g. over ssh/tmux); set `FORCE_HYPERLINK=0` to opt out
- Changed the login-expiry warning to appear 3 days before expiry instead of 5
- Capped the frontend-design plugin suggestion tip at 3 lifetime impressions instead of repeating indefinitely
- Added a cap on concurrently-running subagents (default 20, override with `CLAUDE_CODE_MAX_CONCURRENT_SUBAGENTS`) so one message can't fan out unbounded background agents
- Changed subagents to no longer spawn nested subagents by default; set `CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH` to allow deeper nesting
- Fixed `--max-budget-usd` not stopping background subagents: once the cap is reached, new spawns are denied and running background agents are halted

## 2.1.216

- Added `sandbox.filesystem.disabled` setting to skip filesystem isolation while keeping network egress control
- Fixed a slowdown in long sessions where message normalization cost grew quadratically with the number of turns, causing multi-second stalls and slow resumes
- Fixed auto mode denying commands with "HTTP 401" classifier errors after the OAuth token expired or rotated mid-session
- Fixed AskUserQuestion telling Claude to continue even when your answer asked it to wait or explain first — free-text answers now get neutral wording
- Fixed Claude Code on the web re-asking the same question and dropping your answer after the session sat idle for a few minutes
- Fixed @-mentions silently attaching nothing after file-modifying hooks, vim dot-repeat of `c`-operators and paste, statusline running twice on resume, and resume-picker hangs on failure
- Fixed resumed background agent sessions reverting to the default agent: the agent's prompt and tool restrictions are now restored
- Fixed worktree-isolated subagents redirecting git into the shared checkout via `git -C`, `--git-dir`, or `GIT_DIR`/`GIT_WORK_TREE`
- Fixed worktree sessions landing in another project's leftover worktree when the working directory did not match the selected project
- Fixed background sessions whose worktree has no git repository being undeletable
- Fixed `claude daemon stop --any` potentially terminating an unrelated process via a stale legacy daemon lockfile
- Fixed Esc-Esc at an idle prompt not opening the rewind picker in long-running sessions with background tasks
- Fixed Bash command permission checking for compound statements with redirects inside `&&` lists or negations
- Fixed pressing Ctrl+X twice in the agent list failing to delete a session, and deleted sessions reappearing when their background worker had died
- Fixed background subagents getting cancelled when a high-priority message arrives during their startup window
- Fixed mouse and focus garbage in the terminal while a GUI editor from `/memory`, `/plan`, `/keybindings`, or Ctrl+G is open; `/memory` no longer waits for the editor to close
- Fixed Claude-in-Chrome 403-looping on reconnect when the session's OAuth token lacks a required scope
- Fixed workflow saves and scheduled-task writes following a symlink at `.claude`, which could redirect writes outside the project
- Fixed MCP re-authenticate revoking working credentials before the new sign-in succeeds, and the reconnect needs-auth message in background sessions pointing at an unusable command
- Fixed read-only commands on Windows accessing network paths without a permission prompt
- Fixed Bash command parsing of non-ASCII characters to match real shell word boundaries
- Fixed PowerShell tool permission validation of commands containing invisible Unicode characters
- Fixed dialogs in fullscreen mode stretching past the right-hand edge of their panel
- Fixed the `/config` settings list in fullscreen mode clipping its keyboard-hint footer
- Fixed the transcript-mode (Ctrl+O) footer hint wrapping on terminals narrower than 104 columns
- Fixed the Prometheus metrics endpoint (`OTEL_METRICS_EXPORTER=prometheus`) emitting invalid `# UNIT` lines
- Fixed skills and commands changed during a session not appearing in the slash menu until restart
- Fixed plugin skills with a `name` frontmatter field losing their plugin prefix in slash-command autocomplete
- Fixed telemetry misreporting permission denials: failed permission-prompt requests no longer count as user rejections, and user interrupts are now reported as user aborts instead of rejections
- Improved the `/fork` confirmation to one line with the new session's name, `claude attach` id, and a note when the copy shares your checkout
- Improved validation of `git` and `gh` command arguments in the PowerShell tool
- Improved the `/ultrareview` diff-too-large error to show configured limits, measured diff size, and largest contributing files
- Improved `/code-review ultra` empty-diff message to name the exact base ref and suggest passing an explicit base
- Improved the spend limit adjustment prompt to show the server's reason when a spend limit change is rejected
- `/context` now shows an explicit warning when the conversation exceeds the context window, and a failed `/compact` displays as an error
- `/rewind` no longer restores or deletes files through symlinks or hard links at tracked paths and reports how many paths it skipped
- Background sessions: `/mcp` and `/install-github-app` now park a "needs input" request in the agent view when no client is attached
- Updated the bundled dataviz skill: reordered the default chart palette and fixed guidance that suggested direct labels for four-series charts
- [VSCode] Fixed right-to-left text (Arabic, Hebrew, Persian) rendering in the wrong order when mixed with English or code
- Fixed cloud sessions dropping the in-flight message when the session's container restarts mid-turn — the interrupted turn now re-runs on resume instead of leaving the session unresponsive

## 2.1.215

- Claude no longer runs the `/verify` and `/code-review` skills on its own; invoke them with `/verify` or `/code-review` when you want them

## 2.1.214

- Fixed single-segment `dir/**` allow rules like `Edit(src/**)` auto-approving writes to nested `dir/` directories anywhere in the tree instead of only `<cwd>/dir`
- Fixed a permission-check bypass affecting commands run in Windows PowerShell 5.1 sessions
- Fixed Bash permission checks to fail closed on file-descriptor redirect forms that bash parses differently than the permission analyzer
- Fixed Bash permission checks misjudging very long commands — commands over 10,000 characters now always prompt instead of running automatically
- Fixed Bash permission checks treating zsh variable subscripts and modifiers in `[[ ]]` comparisons as inert text — these commands now prompt for approval
- Fixed Bash permission checks to no longer auto-approve certain `help` and `man` commands that could run unsafe options, command substitutions, or backslash paths
- Fixed permission prompts on remote sessions that could proceed before the local confirmation dialog
- Added the EndConversation tool: Claude can end sessions with highly abusive users or jailbreak attempts, as on claude.ai since 2025 — see https://www.anthropic.com/research/end-subset-conversations
- Added a periodic progress heartbeat for long-running tool calls that previously went silent
- Added an ISO `modified` timestamp to memory file frontmatter
- Added `message.uuid`, `client_request_id`, and `tool_source` attributes to OpenTelemetry log events for message-level correlation and tool provenance
- Added `CLAUDE_CODE_OTEL_CONTENT_MAX_LENGTH` to configure the 60 KB truncation limit on OpenTelemetry content attributes
- Added reasoning effort to the `subagentStatusLine` payload, so custom agent rows can render model and effort
- Added permission prompts for `docker` commands (including the Podman `docker` shim) carrying daemon-redirect flags (`--url`, `--connection`, `--identity`, and Podman's remote mode) that previously ran without one
- Fixed a crash when a GrowthBook feature evaluates to null, and a bug where a malformed flag payload could wipe the cached feature flags
- Fixed Bash tool killing the Claude session when a `pkill -f` pattern accidentally matched the CLI's own process (Linux)
- Fixed unbounded memory growth when `--settings` points at a device file or multi-GB file; oversized (>2 MiB) settings files now fail at startup with a clear error
- Fixed streaming turns failing with "Socket is closed" behind corporate proxies on Windows
- Fixed stream-json output truncation at exit for slow-reading SDK/pipeline consumers; the exit drain now scales with queued bytes instead of a flat 2s cap
- Fixed scheduled tasks refusing their own configured prompt as untrusted input — the fired prompt is now delivered as the session's assigned task
- Fixed PowerShell tool commands hanging until timeout when a child process waited on standard input (Windows)
- Fixed Python scripts under the PowerShell tool crashing with UnicodeDecodeError when reading non-UTF-8 data from standard input (Windows)
- Fixed Python scripts run via the PowerShell tool crashing with UnicodeEncodeError on non-ASCII output, and PowerShell 7 error messages containing raw ANSI escape sequences (Windows)
- Fixed the PowerShell tool reporting `where.exe`, `fc.exe`, and `diff.exe` as errors when they return a valid negative answer (Windows)
- Fixed `>` and `>>` under the PowerShell tool on Windows PowerShell 5.1 writing UTF-16LE files that other tools couldn't read as UTF-8
- Fixed a displaced background daemon deleting its successor's control socket on shutdown, which made the next client kill the healthy replacement daemon
- Fixed background sessions parked with `←` or `/background` and left idle keeping the background daemon and a worker process alive indefinitely
- Fixed completed background sessions being impossible to remove via `claude rm` or the agent view once the background service had gone idle
- Fixed background sessions dispatched from a non-git folder being impossible to delete from the agents view
- Fixed reopening a stopped background session failing to restore its saved conversation when an unreadable folder exists in the session store
- Fixed the Remote Control "session ready" push notification firing for sessions where Remote Control was not explicitly enabled
- Fixed `/install-github-app` and the `/mcp` settings menu being blocked in agent-view sessions — they're now refused only in background sessions with no terminal attached
- Fixed plugins enabled via the `--settings` CLI flag not loading (regression since v2.1.181)
- Fixed feature flags going stale in long-running sessions after the OAuth token rotates
- Fixed `/ultrareview` refusing to run in repos with no merge base — it now offers to review all tracked files
- Fixed `claude update` and `claude doctor` hanging silently, and the `/status` System diagnostics section going blank, when a shell-config path is a directory
- Fixed memory frontmatter values being silently truncated at an inline `#` when memory files are saved
- Fixed session cost and token telemetry double-counting on streams that emit multiple cumulative `message_delta` frames
- Fixed a spurious "check your network" warning that appeared while the advisor was thinking
- Fixed hooks with exit code 2 not blocking as documented when the hook's stdout JSON fails schema validation
- Fixed OTel log events emitted outside the turn's async context missing the interaction span's trace context
- Fixed MCP transient errors during prompts/resources refresh clearing the server's slash commands and resources
- Improved the `claude rc` workspace-trust error in the home directory to say trust there is never saved and to suggest running from a project directory
- Changed single-segment `dir/**` hook `if:` conditions to match only `<cwd>/dir`; write `**/dir/**` for any-depth matching. `deny`/`ask` permission rules keep their any-depth match.
- Changed `file` commands using `-m`/`--magic-file` or `-f`/`--files-from` to require permission instead of being auto-allowed as read-only
- Changed keep-alive connection pooling to disable after a stale-connection error, so retries open a fresh socket
- Changed SessionStart hooks to report source `"fork"` when a session begins as a fork instead of `"resume"`

## 2.1.212

- `/fork` now copies your conversation into a new background session (its own row in `claude agents`) while you keep working; the in-session subagent it used to launch is now `/subtask`
- Added `claude auto-mode reset` to restore the default auto-mode configuration, with a confirmation prompt (pass `--yes` to skip)
- Added a session-wide limit on WebSearch tool calls (default 200, tunable via `CLAUDE_CODE_MAX_WEB_SEARCHES_PER_SESSION`) to stop runaway search loops
- Added a per-session cap on subagent spawns (default 200, override with `CLAUDE_CODE_MAX_SUBAGENTS_PER_SESSION`) to stop runaway delegation loops; `/clear` resets the budget
- MCP tool calls running longer than 2 minutes now move to the background automatically so the session stays usable; configure the threshold or disable with `CLAUDE_CODE_MCP_AUTO_BACKGROUND_MS`
- Typing `/resume` in the agent view now opens a picker of past sessions — including sessions deleted from the list — and resumes your pick as a background session
- Fixed plan mode auto-running file-modifying Bash commands (e.g. `touch`, `rm`) without a permission prompt or SDK `canUseTool` callback
- Fixed worktree creation following a repository-committed symlink at `.claude/worktrees`, which could create files outside the repository
- Fixed a `continue:false` hook's halt being dropped when the tool fails or completes mid-stream, and hook infrastructure errors being misreported as user rejections
- Fixed SIGTERM during a running Bash tool orphaning the command's process tree in print/SDK mode; the CLI now aborts the turn, kills the tree, and exits 143
- Fixed `/background` and `claude --bg` failing with "EUNKNOWN: unknown error, uv_spawn" on Windows when Group Policy blocks PowerShell 5.1; the daemon now prefers PowerShell 7
- Fixed shell mode (`!`) not executing commands containing file paths while the path autocomplete popup was open
- Fixed auto-mode denial notifications rendering broken characters when a long denial reason was truncated mid-emoji
- Fixed Ctrl+J not inserting a newline in the agent view dispatch input on terminals with extended key reporting, and surfaced the newline shortcut in the `?` help overlay
- Fixed `/ultrareview` rejecting PR references like `#123`, `PR 123`, and pasted PR URLs; error hints now name the command you actually typed
- Fixed `/ultrareview <branch>` not fetching the branch from origin when it exists remotely; it now suggests the closest branch name on typos
- Fixed `/ultrareview` skipping the billing confirmation in a new conversation after `/clear`
- Fixed `/ultrareview`'s "not a git repository" error on Claude Desktop now suggesting the project's repository folder instead of terminal commands
- Fixed hosted (host-managed) sessions failing at startup when repository settings configured mTLS certs, extra CA bundles, or OAuth scopes; these transport settings are now ignored with a warning
- Fixed a spurious "File has not been read yet" error when editing a file that had been read with offset/limit before resuming a session
- Fixed `ExitWorktree` failing with "no active EnterWorktree session" after resuming a session with `--continue`/`--resume` in print/SDK mode
- Fixed the workflow agent grid staying empty for Remote Control clients that join a session mid-run
- Fixed streaming-mode control requests being marked complete before their handler finished, which could lose the request on session restart
- Fixed background sessions created with `/fork` losing their live-parent protection after a state write failure
- Fixed reopening a stopped background session from the agent view failing silently — it now resumes the session, or shows why it can't and lets you force a restart
- Fixed agent teams: a stopping teammate could send the leader duplicate idle notifications when team initialization re-ran within a session
- Fixed the plan-approval dialog footer splitting "ctrl+g to edit in <editor>" apart when the file path is long
- Fixed the welcome banner keeping its old panel widths after a combined width+height terminal resize in fullscreen mode
- Fixed diff previews losing their line numbers and +/- markers in narrow layouts
- Fixed @-mentions attaching nothing after a partial file read, plugin uninstall targeting the wrong marketplace, and false "Command timed out" on exit code 143
- Fixed OpenTelemetry HTTP exports being rejected with 411/400 by Azure Monitor and other endpoints that don't accept chunked transfer encoding
- Fixed OTLP event log records missing `trace_id`/`span_id` when `TRACEPARENT` is set in SDK/headless mode
- Fixed conversations with many images incorrectly failing with "Request too large" errors, and improved the error message to explain the actual cause
- Fixed web search and web fetch returning "API Error" text as search results or page content when the API was overloaded
- Improved web search and web fetch reliability by retrying 529 errors and rate-limited requests with bounded backoff
- Improved prompt caching: the mid-conversation system block now works behind LLM gateways and custom base URLs (Bedrock, Vertex, 1P)
- Improved background agent attach: cold-attaching now instantly shows the formatted transcript while the session boots, instead of a blank wait
- Reduced token usage in inter-agent messaging: `SendMessage` bodies are no longer duplicated into replayed history and tool results
- Changed `/fork` to name the copy after your prompt when the session has no title, so the row is recognizable in the agent view
- Changed bare `/btw` to reopen the side-question panel on your most recent exchange so you can browse earlier answers
- Changed the `←` footer hint to pulse `N done` for a moment when a background agent finishes while nothing needs your input
- Deprecated the Task tool's `mode` parameter (now ignored); subagents inherit the parent session's permission mode by default
- Changed Enterprise `forceLoginMethod` to be enforced for VS Code extension, SDK, `setup-token`, and `install-github-app` logins, not just the terminal
- Changed session transcripts to record the reasoning effort level on each assistant message
- Changed headless/SDK sessions to apply a `set_model` control request mid-turn; the next model round-trip uses the new model instead of waiting for the next turn
- Changed agent view / `claude agents --json`: sessions waiting on a sandbox, MCP-input, or managed-settings prompt now show as "Needs input" instead of "Working"
- Updated the auth status panel title from "Cloud authentication" to "Authentication"
- Corrected an earlier release note (2.1.200): tmux through the 3.6 series lacks synchronized output; newer tmux with support is detected automatically

## 2.1.211

- Added `--forward-subagent-text` flag and `CLAUDE_CODE_FORWARD_SUBAGENT_TEXT` environment variable to include subagent text and thinking in stream-json output
- Fixed permission previews relayed to chat channels not neutralizing bidirectional-override, zero-width, and look-alike quote characters, so tool inputs cannot visually alter the approval message
- Fixed auto mode overriding a PreToolUse hook's `ask` decision for unsandboxed Bash — a hook `ask` now floors the decision at a prompt
- Fixed parallel Claude Code sessions all logging out simultaneously after wake-from-sleep when many sessions share one credential store
- Fixed plugin MCP servers not reconnecting after an idle web session woke, leaving MCP calls failing until the next message
- Fixed Claude Code on Vertex and Bedrock attempting the default Opus model at startup and printing a spurious fallback notice when a model is explicitly configured
- Fixed subagents spawned with an explicit model override reverting to the parent's model when resumed or sent a follow-up message
- Fixed nested `.claude/rules/*.md` files loading even when setting sources exclude project settings
- Fixed file upload validation: filenames ending in a DOS device suffix (`.prn`) or trailing dot are now accepted, and files with multiple hard links are refused
- Fixed file uploads to Claude in Chrome from remote and CLI sessions
- Fixed edits that leave the input as "?" being silently swallowed and toggling the shortcuts panel
- Fixed a startup hang when the Claude in Chrome extension is enabled but Chrome is not running
- Fixed a 300ms delay revealing async content (Settings tabs, Stats, diff views, and other loading states)
- Fixed reopening a just-stopped background session from the agents view starting a blank conversation under the same session id
- Fixed `/loop` hiding the session from `/resume` after a single use
- Fixed screen reader users losing the audible terminal bell after `/terminal-setup` or onboarding terminal setup
- Fixed background jobs on LLM gateway auth (`ANTHROPIC_AUTH_TOKEN` + `ANTHROPIC_BASE_URL`) coming back "Not logged in" after the daemon respawns them
- Fixed `claude agents` jobs becoming permanently undeletable when git no longer recognizes their worktree — the row now shows why the delete was refused instead of silently reappearing
- Fixed `/clear` not resetting the session cost counter — the statusline's cost now starts at $0 after `/clear`
- Fixed Claude in Chrome setup pages failing to open in the browser on Windows
- Fixed headless print-mode sessions on Windows crashing or silently exiting when stdin is unreadable
- Fixed background session titles in the agents view showing the naming model's refusal text when the prompt contains a link
- Fixed background agents killed by the user auto-respawning, and revived agents re-running stale prompts from old sessions
- Fixed routines with no schedule reporting a next run time in the year 1
- Hardened synced skill/plugin directory naming on Windows and kept CCR web fetch/search proxies working after `/clear`
- Improved terminal layout and rendering performance
- Improved background agent result reporting — Claude now reports the status of still-running agents and waits for the real completion instead of fabricating results
- Improved the memory index over-limit warning to measure only loaded content, excluding frontmatter and HTML comments
- Updated integer environment variables (timeouts, token budgets, retry counts) to accept scientific notation and digit-separator spellings like `1e6` and `64_000`
- Updated documentation links to the current docs sites
- Changed "always allow" permission rules to save at the repository root, so approvals granted in a git worktree persist across sessions and worktrees
- Changed `/usage-credits` to ask for confirmation before sending a request to organization admins
- Changed Vim mode `s` and `S` (substitute char/line) to work in NORMAL mode, matching vim behavior
- [VSCode] Updated the Remote Control banner to describe what it does
- Claude in Chrome: hardened file-upload path validation
- Claude in Chrome: `save_to_disk` on screenshot actions now writes the image to disk and returns the path; previously it did nothing
- Fixed a prompt-caching regression on Bedrock, Vertex, Mantle, and Foundry that billed the trailing system context block as fresh input tokens on every request.

## 2.1.210

- Added a live elapsed-time counter to the collapsed tool summary line so long-running tool calls visibly tick instead of looking stuck
- Added a startup warning for `Write(path)`, `NotebookEdit(path)`, and `Glob(path)` permission rules — use `Edit(path)` or `Read(path)` instead
- Fixed `isolation: 'worktree'` subagents being able to run git-mutating commands against the main repo checkout instead of their own isolated worktree
- Fixed the `ultracode` keyword opt-in firing on non-human-originated input such as webhook payloads and relayed PR comments
- Fixed a rendered text fragment leaking into crash telemetry when a UI component returned content outside a styled text element
- Fixed paste markers leaking into external editors opened from Claude Code, which could appear as stray È/É characters around pasted text
- Fixed `claude attach` sometimes failing with "job not found" or "agent is still starting" errors during session transitions — attach now waits for the daemon to settle, and terminal resizes during a slow attach are applied once it completes
- Fixed a session crash when a tool's result renderer returned a numeric bigint value or plain text instead of a UI element
- Fixed a hook callback timeout being misreported to the model as a user rejection, which made unattended sessions stop and wait
- Fixed Claude assuming a `cd` took effect after its command was moved to the background; the tool result now states the working directory is unchanged
- Fixed plugin-provided MCP servers being torn down when MCP servers are re-synced mid-session
- Fixed plan approvals without edits being labeled "(edited by user)" and overwriting the plan file with a stale snapshot
- Fixed `/doctor` skipping its auto-mode-default proposal on Bedrock, Vertex, and Foundry, where auto mode no longer needs an opt-in
- Fixed Grep content mode claiming "No matches found" when paginating past the end of results
- Fixed unmatched `$1`/`$2` positional placeholders in skills and commands being silently stripped; they are now preserved verbatim
- Fixed plugin cache writes leaving temp files behind on failure and failing on locked-file renames on Windows and network filesystems
- Fixed background workers crash-looping when a client resets its connection to the background service
- Fixed `claude agents --effort ultracode` not reaching dispatched sessions; the value was silently dropped
- Fixed pressing ← to open the agents view dropping the task tracker when returning to the session
- Fixed the agents dashboard retaining pasted images from abandoned reply drafts after their session was deleted
- Fixed killed background sessions leaving a permanent `git worktree lock` behind; the periodic sweep now releases locks whose owning process is gone
- Fixed SDK MCP servers registered via an `initialize` control request waiting until the next turn to start connecting
- Fixed returning to the agents view from a session leaving overlapping ghost frames with `CLAUDE_CODE_DISABLE_ALTERNATE_SCREEN=1`
- Fixed late-appearing `.claude/*` symlinks not being reconciled into the sandbox deny-write list
- Hardened the Agent tool against indirect prompt injection via content a subagent read
- Improved the Bash/PowerShell tool message when a command hits its timeout and is auto-backgrounded, so the model can distinguish a hang from an explicit background request
- Improved auto mode: the permission classifier now defaults to Sonnet 5 for external sessions, validated on the session's first request and pinned for the session
- Improved the bundled dataviz skill's chart color validation with perceptual OKLab color difference and recalibrated color-blindness thresholds
- Memory writes that leave a MEMORY.md index over its read limit now produce an explicit error instead of silent truncation
- Screen reader mode now announces permission mode changes aloud when cycling modes with Shift+Tab
- The agents footer hint now shows how many background agents are waiting on your input, with a brief color emphasis when the count changes
- Agent view: the session you pressed ← from stays visibly marked even after mouse hover or arrow keys move the selection
- Fable temporarily shows as unavailable in the advisor picker while a server-side issue causing Fable advisor failures is fixed

## 2.1.209

- Fixed /model and other dialogs being blocked in `claude agents` background sessions (reverts an overly broad guard)

## 2.1.208

- Added screen reader mode: opt-in plain-text rendering for screen reader users. Run `claude --ax-screen-reader`, set CLAUDE_AX_SCREEN_READER=1, or add "axScreenReader": true to settings.
- Added `vimInsertModeRemaps` setting: map two-key insert-mode sequences like `jj` to Escape in vim mode
- Added `CLAUDE_CODE_PROCESS_WRAPPER`: agent view and the background service now honor a corporate launcher by running every Claude Code self-spawn through a required wrapper executable
- Added mouse-click support for multi-select menus and "Other" input rows in fullscreen mode
- Changed the Fable 5 usage-credits consent prompt to start with the decline option focused
- Fixed fast mode staying off after switching back to a model that supports it — it now restores automatically when enabled in settings
- Fixed replies typed to a background agent being lost when delivery fails — the text is now saved and delivered when the session restarts
- Fixed background-session attach failing permanently ("Couldn't start the background daemon") after an update replaced the binary a running `claude agents` process was launched from
- Fixed the context window (and auto-compact indicator) briefly resetting to 200k after the CLI auto-updates, causing a false "100% context used" when resuming long-context sessions
- Fixed supervised and background sessions crashing when a server closed an HTTP/2 connection with a GOAWAY while requests were in flight
- Fixed truncated stream-json/JSON output and missing result message when piping large responses from `claude -p`
- Fixed `CLAUDE_CODE_MAX_OUTPUT_TOKENS` and similar env vars silently using the mantissa of scientific-notation values (`1e6` became `1`)
- Fixed very large markdown tables stalling rendering or using excessive memory; tables over 200 rows show the first 200 with a "… N more rows" notice
- Fixed the Edit tool failing on files modified after reading when the target text still matches uniquely
- Fixed Read reporting empty files as "shorter than offset", Grep silently returning "No files found" for invalid regex patterns, Grep count mode under-reporting totals when paginated, and Glob crashing with an unclear error when the pattern, path, or working directory contained a null byte
- Fixed `apiKeyHelper` script failures being hidden behind a generic 401 after ~10 silent retries; the script's own error is now shown within 3 attempts
- Fixed Bedrock streaming requests failing with a misleading "Truncated event message received" when a gateway transforms the response — the error now names the content-type and points at the proxy
- Fixed `/upgrade` showing a login flow instead of the upgrade URL when the browser fails to open
- Fixed stream-json input killing the session on blank CRLF or whitespace-only lines from Windows-style SDK hosts
- Fixed headless stream-json sessions hanging permanently when a `control_request` carried a non-string `set_model` payload; the CLI now answers with an error response
- Fixed repeated "No completion record was found" notices on session resume — orphaned background tasks now collapse into a single summary
- Fixed Remote Control clients attaching to a terminal-hosted session not seeing background agents and workflow progress until a task started or stopped
- Fixed the Agent tool launching with no tools when a subagent's `tools` list resolves to nothing — it now returns a clear error naming the unrecognized entries
- Fixed `/usage` showing stale cached bars over fresher data, and `/mcp` not reclassifying placeholder servers after config edits
- Fixed "Change directory" in SDK hosts (e.g. Claude Desktop) failing with "A turn is in progress" on idle sessions that have a running background task
- Fixed the workflow save dialog showing `~/.claude/workflows/` instead of the `CLAUDE_CONFIG_DIR` location for user-scope saves
- Fixed `/release-notes` adding the viewed notes to the model's context — "Show all" previously injected the entire changelog into every subsequent request
- Fixed a memory leak in the agent view where pasted images were retained for the screen's lifetime after sending peek replies
- Fixed SDK sessions losing agents defined via the initialize request when a plugin refresh ran before the client attached
- Fixed several memory leaks in long sessions: MCP stdio server stderr accumulating up to 64 MB per server, LSP documents staying open indefinitely (now LRU with 50-doc cap), async hook output retained after backgrounding, and unbounded growth in headless/SDK sessions from large tool-result payloads
- Fixed a memory blowup when reading files with extremely long single lines using offset/limit — the read now returns a clean error instead of loading the whole line
- Fixed multi-second per-turn slowdowns in sessions with many permission deny/ask rules — rule matchers are now compiled once and cached
- Improved input responsiveness while agent task lists update — task updates no longer re-render the entire UI
- Reduced per-tool-call CPU overhead in print/SDK sessions with many MCP tools by caching tool-pool assembly (up to 7x faster tool rounds at high tool counts)
- Reduced memory usage by bounding the file edit read cache to 16 MB instead of pinning up to 1,000 full files
- Reduced session transcript size (up to 79x in edit-heavy sessions) and bounded checkpoint disk usage by pruning superseded file-history backups
- Reduced memory usage when resuming sessions with background agents or forks spawned from large conversations
- Completed background agents now stay listed in `/tasks` until cleanup instead of vanishing the moment they finish
- Attaching to a stopped background agent now shows its transcript immediately while the session warms up, instead of a blank "Session is starting" screen
- Background sessions: an older daemon no longer silently restarts workers spawned by a newer version onto the older binary
- Agent view: Ctrl+X now deletes renamed-branch worktrees, never destroys unpushed commits, keeps the session row when a worktree is kept, and reused worktree names reset to the current base
- Catastrophic removals (e.g. `rm -rf ~`) in commands containing `$(…)`/backticks/`<(…)` now prompt in `--dangerously-skip-permissions` and auto mode, matching the plain form
- `/install-github-app` and the `/mcp` settings menu no longer open in background sessions
- MCP servers configured with an empty URL now show as "not configured" in `/mcp` instead of a config error
- `/usage` now shows your last-known usage bars with an "as of" note when the usage endpoint is rate-limited, instead of an error screen
- Fixed Bedrock auth failing with "Session token not found or invalid" for AWS SSO profiles whose sso_region differs from the Bedrock region (2.1.207 regression)

## 2.1.207

- Auto mode is now available without `CLAUDE_CODE_ENABLE_AUTO_MODE` opt-in on Bedrock, Vertex AI, and Foundry; disable via `disableAutoMode` in settings
- Fixed the terminal freezing and keystrokes lagging while streaming responses containing very long lists, tables, paragraphs, or code blocks
- Fixed remote managed settings from a non-interactive run (`claude -p`, the SDK) being permanently recorded as consented without ever showing the security consent dialog
- Fixed spurious prompt-injection warnings triggered by benign system-generated conversation updates
- Fixed the auto-updater overwriting a custom launcher script or symlink at `~/.local/bin/claude` on every release; `/doctor` now reports an externally managed launcher
- Fixed compound commands with `cd` prompting for permission when the only output redirect was to `/dev/null`
- Fixed the transcript jumping above the start of the answer when a response finishes streaming
- Fixed `extensions.worktreeConfig` being left in the repo's `.git/config` (breaking go-git tools like `tea`) after the last `worktree.sparsePaths` worktree was removed
- Fixed malformed bracket patterns in rules globs, skill paths, `.ignore`, and `.worktreeinclude` breaking file reads, file suggestions, and worktree creation
- Fixed a crash loop in agent teams where a malformed teammate mailbox message caused repeated errors every second until the mailbox file was manually deleted
- Fixed background sessions auto-named by accepting a plan not showing that name on their agent-view row
- Fixed background sessions that entered a git worktree resuming blank after a cold reopen from the agent list
- Fixed Remote Control task status updates being lost when the connection recovered from a network interruption or credential refresh
- Fixed Remote Control sessions hosted by the desktop app not showing background agent and workflow progress on mobile and web
- Fixed Deep research runs labeling every Fetch-phase agent "unknown" — chips now show the source hostname
- Fixed Bedrock repeatedly requesting fresh AWS SSO credentials from IAM Identity Center on every API request
- Improved agent view: pasting the same text again now expands the collapsed `[Pasted text #N]` placeholder instead of adding a second one
- Improved agent view: blocked session peeks now lead with the question and show a worded staleness clock (`waiting 3m`) instead of the same timestamp twice
- Changed Bedrock, Vertex, and Claude Platform on AWS to default to Claude Opus 4.8
- Changed auto mode to no longer read `autoMode` from `.claude/settings.local.json` (repo-resident); use `~/.claude/settings.json` instead
- Fixed an indefinite hang on Windows when AWS credential resolution stalls (e.g. a stuck `credential_process`): the 60-second stall guard now fires instead of waiting forever.
- Plugin hooks/monitors/MCP headersHelper: `${user_config.*}` in shell-form commands is now rejected (shell-injection fix). Hooks: use exec form (`args` array) or `$CLAUDE_PLUGIN_OPTION_<KEY>`; monitors and headersHelper: read the value inside the script (config file or the server's `env` block).
- Plugin option values (`pluginConfigs`) are no longer read from project-level `.claude/settings.json`; only user, `--settings`, and managed settings are honored
- Fixed `/usage-credits` amount inputs silently stripping malformed values (e.g. a pasted timestamp) to digits; malformed amounts are now rejected with an error, and amounts over $1,000 require a typed confirmation

## 2.1.206

- Added directory path suggestions to `/cd`, matching `/add-dir` behavior
- Added a `/doctor` check that proposes trimming checked-in `CLAUDE.md` files by cutting content Claude could derive from the codebase

- `EnterWorktree` now asks for confirmation before entering a git worktree outside the project's `.claude/worktrees/` directory
- Background agents now upgrade to a new version in the background right after a Claude Code update, instead of paying a slow stale-session upgrade when you attach
- Fixed an expired login failing every model with a misleading "There's an issue with the selected model" error instead of prompting to run `/login`
- Fixed `claude --resume` and `--continue` not responding to keyboard input on startup
- Fixed MCP servers configured via `--mcp-config` or `.mcp.json` ignoring a per-server `request_timeout_ms`, which caused long-running MCP tool calls to time out at the 60s default in fresh sessions
- Fixed `CLAUDE_CODE_EXTRA_BODY` being silently ignored by `claude agents` / `--bg` background workers; the shell-exported override now follows the dispatching session
- Fixed OAuth MCP servers requiring manual re-authentication after a single failed token refresh
- Fixed `--permission-prompt-tool` pointing at an MCP server crashing with "MCP tool not found" on cold start before the server finishes connecting
- Fixed `/model` picker rows printing a price for a different model than the row named, and stopped quoting first-party list prices on providers that don't bill them

- Bedrock: fixed a multi-minute startup hang when using an `awsCredentialExport` helper on networks with restricted egress
- Improved `/code-review` findings quality on claude-opus-4-8 across all effort levels
- Improved agents view: status column now uses full terminal width instead of truncating at 64 characters
- Changed agents view: Ctrl+X now permanently removes a completed session, and sessions no longer render twice; deleted background jobs stay deleted

## 2.1.205

- Added an auto mode rule that blocks tampering with session transcript files
- Fixed `--json-schema` silently producing unstructured output when the schema was invalid, and schemas using the `format` keyword being rejected
- Fixed a message sent while Claude was working being silently lost when the turn ended at the `--max-turns` limit

- Fixed a plugin LSP server that fails to initialize preventing a valid LSP server from another plugin handling the same file extension
- Fixed a Windows crash when the directory Claude was launched from is deleted, locked, or unmounted while a command is running
- Fixed a crash when a file watcher was closed while a directory scan was still in flight
- Fixed project verify skills being rewritten on every session instead of only when a documented command changed
- Fixed the agent view rendering one line too high and clipping its header when the job list slightly overflowed the screen
- Fixed background tasks in the web and mobile Remote Control panels showing stale "Running" status by forwarding full task state on every membership change
- Improved auto mode to ask before running `rm -rf` on a variable it can't resolve from context
- Auto-update binary downloads now stream to disk instead of buffering in memory, cutting the updater's peak memory usage by roughly 400 MB
- Background task notifications now explicitly state that no human input has occurred, preventing fabricated in-transcript approvals from being acted on
- Improved agent view: sessions that edit, merge, comment on, or push to an existing PR now link it in `claude agents`
- Improved agent view: rows now show a colored state word and a classifier-written headline instead of raw tool call text, and the peek opens with full status including the exact ask for blocked sessions
- `/doctor` is now a full setup checkup that can diagnose and fix issues; `/checkup` is its alias
- Reserved the "Claude Browser" MCP server name (alongside "Claude Preview") ahead of the Claude Desktop pane rename; user-configured MCP servers can no longer register under either name
- Fixed Cowork VM-mode local-agent sessions failing to start with "Not logged in · Please run /login" on CLI 2.1.203+

## 2.1.204

- Fixed hook events not streaming during SessionStart hooks in headless sessions, which could cause remote workers to be idle-reaped mid-hook

## 2.1.203

- Added a warning when your login is about to expire, so you can re-authenticate before background sessions are interrupted
- Added a grey ⏸ badge to the footer when in manual permission mode, making the active mode always visible
- Added the session's additional working directories to MCP `roots/list`, with `notifications/roots/list_changed` sent when the set changes
- Fixed opening or switching background agent sessions on macOS stalling for 15–20 seconds due to a false low-memory detection (regression in 2.1.196)
- Fixed background sessions becoming permanently unresponsive to attach, replies, and stop when the daemon's session token went stale — the session now recovers automatically
- Fixed returning to `claude agents` silently stopping running subagents and re-running the prompt from scratch — their work now carries over
- Fixed a memory and per-turn CPU regression in interactive sessions: the context-usage indicator no longer re-analyzes the entire transcript after every turn
- Fixed background agents inheriting a stale `PATH` from the daemon instead of the dispatching shell, causing missing tools on Windows
- Fixed background and agent-view sessions dropping a shell-exported `ANTHROPIC_BASE_URL`, which sent API keys to the default endpoint and failed with 401
- Fixed Bash failing with "argument list too long" in repos with many git worktrees
- Fixed worktree-isolated subagents sometimes running shell commands in the parent checkout instead of their own worktree
- Fixed worktree creation rejecting nested repositories in multi-repo workspaces, leaving background sessions unable to isolate and edit
- Fixed background agents crash-looping when their working directory was deleted, replaced by a file, or became an invalid path — they now fail once with a clear error
- Fixed a background daemon auto-upgrade failure silently killing all running background sessions
- Fixed `TaskStop` and `TaskOutput` failing to find background agents spawned by another agent — errors now list running agents by id and description
- Fixed the `claude agents` composer discarding your typed message when a slash command isn't available there

- Fixed LSP-only plugins being incorrectly flagged for disuse when their language servers deliver diagnostics or answer navigation requests
- Improved responsiveness while long responses stream: live-preview updates no longer re-render the whole screen
- Improved subagent behavior: agents are now less likely to re-delegate their entire task to another subagent
- Reduced binary size by ~7 MB and startup memory by ~7 MB by loading a large bundled dependency lazily instead of inlining it
- Changed left arrow to no longer close the background tasks, diff, and workflow detail views — press Esc instead
- Changed the empty `claude agents` view to always show the organized sections (Needs input / Working / Completed) with descriptions
- Removed the startup "claude command missing or broken" warnings — they now appear in `/doctor` and `/status` instead
- Removed a redundant navigation hint from the `claude agents` footer
- [VSCode] Added a Settings toggle for "Enable Remote Control for all sessions"

## 2.1.202

- Added a "Dynamic workflow size" setting in `/config` for controlling how large Claude generally makes dynamic workflows (small/medium/large agent counts) — an advisory guideline, not an enforced cap
- Added `workflow.run_id` and `workflow.name` OpenTelemetry attributes to telemetry emitted by workflow-spawned agents, so a workflow run's activity can be reconstructed from OTel data
- Fixed a crash in the inline Ctrl+R history search when accepting or cancelling while the search was still scanning the history file
- Fixed `/rename` on background sessions being reverted when the job restarts, which broke addressing the session by its new name

- Fixed images and files sent from the Remote Control mobile or web app without a caption being silently dropped
- Fixed the sign-in URL printed by `claude auth login` and `claude mcp login --no-browser` not being reliably clickable when it wraps over SSH — it is now emitted as a single hyperlink
- Fixed opening a chat from `claude agents` sometimes failing with "currently running as a background agent" followed by a worker crash/respawn loop
- Fixed workflow scripts with unicode quote escapes in strings being corrupted before parsing; workflow parse errors now show the offending line instead of always blaming TypeScript
- Fixed voice dictation retrying in an unbounded loop when the microphone or audio recorder fails — repeated capture failures now pause voice input
- Fixed `/remote-control` sessions showing the wrong permission mode in the mobile and web apps
- Fixed resuming a session by name, or opening the resume picker, taking minutes and using a large amount of memory in repositories with many git worktrees
- Fixed installer and updater downloads failing immediately with "aborted" when a proxy or network drops the connection mid-download — transient connection drops now retry
- Fixed re-invoking an already-loaded skill appending a duplicate copy of its instructions to context
- Improved `/workflows` agent list layout: wider titles, a dedicated time column, shorter model names, and no per-row tool-call counts
- Improved MCP error messages: clearer error when a server config has `url` but no `type`, suggesting `"type": "http"` instead of the misleading "command: expected string"
- Changed `/review <pr>` back to a fast single-pass review; use `/code-review <level> <pr#>` for the multi-agent review at a chosen effort level

## 2.1.201

- Claude Sonnet 5 sessions no longer use the mid-conversation system role for harness reminders

## 2.1.200

- Changed `AskUserQuestion` dialogs to no longer auto-continue by default; opt into an idle timeout via `/config`

- Fixed background sessions silently stopping mid-turn after sleep/wake or when reopening a stalled session
- Fixed background sessions re-running a turn cancelled with Esc after a stall respawn
- Fixed background agents never starting again after a crash left a stale `daemon.lock` whose PID the OS reused
- Fixed background-agent daemon handover so a reinstalled older build can no longer take over the daemon; build recency is now judged by the version's embedded build timestamp
- Fixed background-agent roster issues: transient corruption permanently disabling orphan cleanup, older binaries not preserving fields written by newer versions, and socket auth tokens being stripped during daemon restarts
- Fixed subagents cut off by a rate limit before producing any text output returning an empty result instead of failing cleanly
- Fixed control bytes from background-agent output reaching the terminal in the agent view

- Improved the install script to explain when installation is killed by the system running out of memory

## 2.1.199

- Stacked slash-skill invocations like `/skill-a /skill-b do XYZ` now load all leading skills (up to 5), not just the first
- Fixed SSL certificate errors (TLS-inspecting proxies, missing `NODE_EXTRA_CA_CERTS`, expired certs) burning retries before showing actionable guidance — they now fail immediately with the fix hint
- Fixed streaming responses being discarded when the API emits a mid-stream overloaded/server error after partial output — the partial is now kept with an incomplete-response notice
- Fixed subagents cut off by a rate limit or server error silently failing instead of returning their partial work to the parent
- Fixed subagents reporting API errors (e.g. usage limit reached) as successful results — the error is now reported to the parent agent
- Fixed the background-agent daemon on Linux killing itself and every running agent every ~50 seconds after an unclean shutdown left a corrupted worker record
- Fixed background agents failing to cold-start over SSH on macOS with "Could not switch to audit session" (regression in 2.1.196)
- Fixed `claude stop` being silently undone when it raced a background-agent respawn — the respawn now honors the stop
- Fixed background job progress indicators stalling for minutes while the job ran long commands
- Fixed background sessions on memory-starved machines showing a generic error — they now indicate low memory and suggest freeing resources
- Fixed remote sessions briefly flapping between Working and Idle in the agent view when a background agent completes
- Fixed idle subagents vanishing from the agent panel while other subagents were still working; surplus idle agents now collapse into an expandable summary row
- Fixed typing `/model` or `/fast` while viewing a subagent silently opening the lead's model picker — a notice now explains the command applies to the lead
- Fixed `SessionStart`, `Setup`, and `SubagentStart` hooks silently hiding stderr when exiting with code 2 — the error is now shown in the transcript
- Fixed `claude --dangerously-skip-permissions daemon <subcommand>` being treated as a chat prompt instead of running the subcommand
- Fixed `SendMessage` silently misrouting when a re-spawned agent reuses a previous agent's name — the tool now detects the mismatch and asks the caller to retarget
- Fixed opening or resuming a session with no new messages needlessly growing the transcript file
- Fixed backgrounding a session with `←` or `/background` dropping its `/color` from the agent view row
- Fixed resetting a corrupted config file from the startup recovery dialog destroying it unrecoverably — it now backs up the file first
- Fixed Claude in Chrome repeatedly opening the reconnect page when sessions run from different builds or config directories
- Fixed plan mode not prompting for state-changing browser tool calls; read-only `browser_batch` calls are now correctly auto-allowed
- Transient server rate-limit errors (429s unrelated to your usage limit) are now retried automatically with backoff for subscribers instead of failing the turn
- `CLAUDE_CODE_RETRY_WATCHDOG` now raises the default retry count for non-capacity transient errors to 300 and lifts the cap of 15 on `CLAUDE_CODE_MAX_RETRIES`
- `claude agents` session rows now show pull-request links as bare `#N` without the redundant "PR" label

## 2.1.198

- Subagents now run in the background by default, so Claude keeps working while they run and is notified when they finish (previously a gradual rollout)
- Claude in Chrome is now generally available
- Added background agent notifications in `claude agents` — sessions that need input or finish now fire the `Notification` hook (`agent_needs_input` / `agent_completed`)
- Added `/dataviz` skill for chart and dashboard design guidance with a runnable color-palette validator
- Gateway: added Claude Platform on AWS (anthropicAws) as an upstream provider; model-not-found responses now advance the failover chain
- Background agents launched from `claude agents` now commit, push, and open a draft PR when they finish code work in a worktree, instead of stopping to ask
- The built-in Explore agent now inherits the main session's model (capped at opus) instead of running on haiku
- Subagents and context compaction now inherit the session's extended thinking configuration, improving output quality on delegated tasks
- Fixed brief network drops mid-response aborting the turn — transient errors like ECONNRESET now retry with backoff instead of failing
- Fixed excessive background classifier requests when sandboxed processes repeatedly accessed the same network host
- Fixed background tasks in web, desktop, and VS Code task panels getting stuck on "Running" after they finish or after resuming a session
- Fixed agent teams: a teammate that dies on an API error now reports "failed" to the lead, and messaging a stuck teammate wakes it to retry immediately
- Fixed the `/diff` panel not refreshing when you switch branches or commit outside the session
- Fixed markdown tables overflowing and wrapping their right border when rendered in fullscreen mode
- Fixed Claude Platform on AWS and Mantle sessions dead-ending with "Please run /login" when the STS token expires — `awsAuthRefresh` now runs automatically

- Fixed `/desktop` failing with "Cannot determine working directory" after entering and exiting a worktree
- Fixed background agents repeatedly showing "Reconnecting…" every ~52 seconds on macOS while the agents view was open
- Fixed pressing `←` inside `claude attach <id>` exiting to the shell instead of opening the agent view

- Fixed double-click word selection in fullscreen mode to select the entire URL including the scheme
- Fixed plan mode not auto-allowing read-only tool calls when a session starts in plan mode
- Fixed `/branch` deriving its default fork name from the compaction summary instead of the first real prompt
- Improved focus mode: subagents launched in a turn now appear in its activity summary, and completed background notifications fold into a single count
- Improved syntax highlighting accuracy in code blocks, diffs, and file previews by upgrading to highlight.js 11
- Keyboard shortcut hints now show opt/cmd instead of alt/super when connected from a Mac over SSH
- Improved API retry UX: the error reason is now shown after the second attempt, and a status page link replaces the spinner tip when the API is overloaded
- `/login` now opens the sign-in dialog from the `claude agents` view instead of saying it isn't available
- Subagents now treat messages from the agent that launched them as normal task direction; an agent's message is still never treated as the user's approval
- Removed the `/agents` wizard; ask Claude to create or manage subagents, or edit `.claude/agents/` directly

## 2.1.197

- Introducing Claude Sonnet 5: now the default model in Claude Code, with a native 1M-token context window and promotional pricing of $2/$10 per Mtok through August 31. Update to version 2.1.197 for access. https://www.anthropic.com/news/claude-sonnet-5

- Added readable default names for sessions at start, making them easier to identify and message
- Added clickable file attachments in chat — Cmd/Ctrl-click reveals the file in Finder/Explorer
- Security: `claude mcp list`/`get` no longer spawn `.mcp.json` servers that a repo self-approved via a committed `.claude/settings.json`; untrusted workspaces show `⏸ Pending approval`
- Fixed waking a background job permanently deleting its conversation and re-running the original prompt when the transcript probe misread a real transcript; the file is now set aside, never deleted
- Fixed the rate-limit warning flickering off and rate-limit telemetry being over-counted when multiple parallel requests were in flight at the moment a usage limit was hit
- Fixed duplicate recap lines after a background session's turn: a schema-rejected StructuredOutput attempt no longer renders alongside its retry
- Fixed PowerShell `git diff`/`git grep`, `egrep`/`fgrep`, and quoted search patterns containing `|` being reported as failures when they exit 1, matching Bash behavior
- Fixed multiple `claude agents` side panel issues: keyboard focus getting stuck when opening an agent, background jobs losing their subagent types on every open, and sessions showing incorrect status while actively running
- Fixed `claude agents --dangerously-skip-permissions` silently falling back to auto mode instead of showing the bypass disclaimer and applying bypass mode to spawned agents
- Fixed mid-turn crash recovery for Remote sessions — sessions interrupted by a server restart now auto-resume on the next worker
- Fixed sessions moved with `/cd` reappearing in the old directory's resume list after a non-graceful exit when the old path contained special characters
- Fixed `claude plugin validate` skipping local plugins whose source is "." and stopping after the first error class
- Fixed Esc Esc at an idle prompt not opening the rewind menu (regression); use Ctrl+C or Ctrl+X Ctrl+K to stop background agents
- Fixed MCP OAuth requesting the authorization server's full `scopes_supported` catalog when no scope is specified, causing `invalid_scope` failures on GitLab self-hosted and other enterprise IdPs
- Fixed `/context` showing 0 tokens for all tool groups on Bedrock
- Fixed `/deep-research` misreporting verifier failures as "all claims refuted" instead of `unverified`
- Fixed plugin dependency version pins not being honored when the marketplace was added as a local folder path backed by a git repo
- Fixed `claude agents` session status: completed rows no longer flip between "Done" and "Needs your input", stalled agents are now labeled "Needs attention", and results that mention a PR show a clickable link
- Fixed voice dictation swallowing spaces and spuriously starting a recording during very fast typing when voice mode is enabled
- Improved background session reliability: long-running commands and workflows now survive the session's process being stopped, restarted, or updated — including on Windows, where background shells are handed off instead of being killed
- Improved background agents: workers killed by a daemon restart are now automatically resumed from where they left off the next time the agents view opens
- Improved `/code-review` workflow: merged five cleanup finders into one, cutting token usage by roughly 25%
- Reduced per-frame rendering work in the terminal UI by skipping no-op subtree walks during streaming
- The streaming idle watchdog is now on by default for all providers — it aborts and retries when a response stream produces no events for 5 minutes. Set `CLAUDE_ENABLE_STREAM_WATCHDOG=0` to disable.
- Remote Control is now disabled when `ANTHROPIC_BASE_URL` points at a non-Anthropic host, matching the existing behavior under `CLAUDE_CODE_USE_BEDROCK`/`_VERTEX`/`_FOUNDRY`
- Changed opening the agents view from a foreground session to require a single `←` press instead of two, matching the behavior in background sessions

## 2.1.195

- Added `CLAUDE_CODE_DISABLE_MOUSE_CLICKS` to disable mouse click/drag/hover in fullscreen mode while keeping wheel scroll
- Fixed hook matchers with hyphenated identifiers (e.g. `code-reviewer`, `mcp__brave-search`) accidentally substring-matching — they now exact-match. Use `mcp__brave-search__.*` to match all tools from a hyphenated MCP server.
- Fixed voice dictation on macOS capturing silence in long-running sessions after the default input device changes
- Fixed voice dictation auto-submit never firing for languages written without spaces (Japanese, Chinese, Thai)
- Fixed external plugins enabled only by project `.claude/settings.json` not requiring explicit install consent on every loader path
- Fixed `/plugin` Enable/Disable not working when a plugin's `plugin.json` `name` differs from its marketplace entry name
- Fixed background jobs disappearing from `claude agents` or losing data when written by a newer Claude Code version
- Fixed reopening a crashed background task showing a blank screen for up to 5 seconds instead of its restart
- Fixed background agent daemons running unreachable when the control socket fails to start, blocking restarts
- Improved voice mode on Linux: now distinguishes "no microphone" from "SoX not installed" when SoX is present but no audio capture device exists
- Improved `claude agents` completed list to fill available vertical space; on short terminals the header compacts so live sessions stay visible
- Improved Remote session startup with a provisioning checklist while the container starts

## 2.1.193

- Added `autoMode.classifyAllShell` setting to route all Bash/PowerShell commands through the auto-mode classifier instead of only arbitrary-code-execution patterns
- Added auto-mode denial reasons to the transcript, the denial toast, and `/permissions` recent denials
- Added `claude_code.assistant_response` OpenTelemetry log event containing the model's response text. Redacted unless `OTEL_LOG_ASSISTANT_RESPONSES=1`; when that var is unset it follows `OTEL_LOG_USER_PROMPTS`, so deployments that already log prompt content will start receiving response content on upgrade — set `OTEL_LOG_ASSISTANT_RESPONSES=0` to keep prompts-only.
- Added live file path autocomplete to bash mode (`!`)
- Added a startup notice when MCP servers need authentication, pointing at `/mcp`
- Added automatic memory-pressure reaping for idle background shell commands (disable with `CLAUDE_CODE_DISABLE_BG_SHELL_PRESSURE_REAP=1`)
- Fixed `/model` and other client-data-gated UI showing stale/empty state immediately after `/login`
- Fixed backgrounding (←←) spuriously cancelling with "N background tasks would be abandoned" when all running tasks carry over to the new session
- Fixed pinned background agents being re-prompted to "Continue from where you left off" after every auto-update
- Fixed backgrounding the main turn spawning a phantom "general-purpose (resumed)" subagent that re-ran the main conversation
- Fixed agent panel hiding sibling agents when viewing a subagent
- Improved background agents: the launch result no longer instructs Claude to "end your response" — it keeps working on other tasks while the agent runs
- Improved MCP `headersHelper` auth: the helper now re-runs and reconnects automatically when a tool call returns 401/403
- Improved plugin auto-rename: marketplace `renames` maps are now followed automatically, updating your settings to the new name
- Improved `/add-dir` message when the directory is already a working directory

## 2.1.191

- Added `/rewind` support for resuming a conversation from before `/clear` was run
- Fixed scroll position jumping to the bottom while reading earlier output during a streaming response
- Fixed background agents resurrecting after being stopped — stopping an agent from the tasks panel is now permanent
- Fixed `/voice` showing a generic "not available" message when disabled by an organization's policy — it now explains the restriction
- Fixed `/login` URL opening truncated in Windows Terminal when it wraps across lines
- Fixed Cmd+click on links in fullscreen mode for Ghostty over ssh/tmux
- Fixed `claude agents` sending builtin slash commands like `/usage` to background sessions as prompt text instead of showing a hint
- Fixed `claude agents` job rows showing full filesystem paths for pasted images instead of the `[Image #N]` placeholder
- Fixed hooks with comma-separated matchers (e.g. `"Bash,PowerShell"`) silently never firing
- Fixed `/permissions` Recently-denied tab: approving a denial now persists on close instead of being silently discarded
- Fixed the agent panel jumping by one row when scrolling the roster past the overflow cap
- Fixed the welcome splash art overflowing the default 80×24 macOS Terminal window
- Fixed managed settings: `forceRemoteSettingsRefresh` now takes effect when set via MDM or file policy, and the fetch sends `Cache-Control: no-cache` to prevent proxies from serving stale responses
- Improved sandbox network permission dialog: hosts you allow with "Yes" are now remembered for the rest of the session instead of re-prompting on every connection
- Improved MCP server reliability: capability discovery (`tools/list`, `prompts/list`, `resources/list`) now retries transient network errors with short backoff
- Improved MCP OAuth: discovery and token requests now retry once after transient network errors, and headless environments skip the browser popup and go straight to the paste-the-URL prompt
- Improved MCP error messages: HTTP 404 errors now show the URL and point to your MCP config
- Improved vim mode prompt-history search (NORMAL `/`) to hint how to reach slash commands
- Reduced CPU usage during streaming responses by ~37% by coalescing text updates to 100ms
- Reduced long-session memory growth from terminal output cache

## 2.1.190

- Bug fixes and reliability improvements

## 2.1.187

- Added `sandbox.credentials` setting to block sandboxed commands from reading credential files and secret environment variables

- Fixed `--resume` failing with "No conversation found" when the original `-p` run produced no model turns
- Fixed `--json-schema` and workflow `agent({schema})` structured output: the model can no longer re-call `StructuredOutput` indefinitely after a successful call, and follow-up turns now reliably return structured output
- Fixed remote MCP tool calls that hang with no response for 5 minutes — they now abort with an error instead of blocking indefinitely (override with `CLAUDE_CODE_MCP_TOOL_IDLE_TIMEOUT`)
- Fixed Claude Code Remote sessions taking ~2.7s longer to start after the agent proxy CA system-trust install was added
- Fixed pasted Korean/CJK text turning into mojibake in terminals that deliver paste as per-byte extended-key events
- Fixed `/update` over Remote Control hanging when a startup trust dialog would have shown
- Fixed background jobs in the agents view getting stuck in "working" indefinitely when the agent ended a turn without producing structured output
- Fixed channel connections dropping after navigating to the agents view and back, and after `/bg`, `/tui`, or `/update`
- Fixed agent stop notifications not correctly attributing who stopped the agent, and improved wording ("finished"/"stopped" instead of "came to rest")
- Fixed subagent depth tracking: resumed subagents now restore their original spawn depth, and forked subagents now count toward the depth cap
- Fixed leaked agent worktree registrations: locked `.git/worktrees/` entries from killed agents are now cleaned up automatically
- Fixed Cmd+click not opening URLs in fullscreen mode in Ghostty on macOS
- Fixed `claude --help` not listing the `--bg`/`--background` flag
- Fixed Esc, Ctrl-C, and Ctrl-D not working while `/share` is uploading
- Improved `/install-github-app`: GitHub Actions workflow setup is now optional — you can install just the GitHub App and skip the workflow/secret steps
- Improved `/btw` with ←/→ arrow navigation to step through earlier answers
- Improved `/plugin` to surface plugins you haven't used recently so you can clean them up
- [VSCode] Fixed extension becoming unresponsive when resuming a large session

- Added status filtering (press `f`) to the `/workflows` agent detail view
- Added a "Skills" section to the `/plugin` Installed tab
- Added `teammateMode: "iterm2"` setting with a warning when auto mode cannot find the `it2` CLI
- Added "Claude Platform on AWS - refresh credentials" option to `/login` when `awsAuthRefresh` is configured

- Improved skill frontmatter: `display-name`, `default-enabled`, `fallback`, and `metadata.*` keys now accept kebab-case, snake_case, and camelCase
- Improved malformed `SKILL.md` YAML frontmatter handling: loads the skill body with empty metadata instead of failing silently
- Changed `CLAUDE_CODE_MAX_RETRIES` to cap at 15; for unattended sessions, use `CLAUDE_CODE_RETRY_WATCHDOG` instead
- Changed background subagents to surface permission prompts in the main session instead of auto-denying; the dialog shows which agent is asking, and Esc denies just that tool
- Changed `/review <pr>` to use the same review engine as `/code-review medium`

## 2.1.185

- The stream-stall hint now reads "Waiting for API response · will retry in …" instead of "No response from API · Retrying in …", and triggers after 20s of silence instead of 10s

## 2.1.183

- Improved auto mode safety: destructive git commands (`git reset --hard`, `git checkout -- .`, `git clean -fd`, `git stash drop`) are now blocked when you didn't ask to discard local work, `git commit --amend` is blocked when the commit wasn't made by the agent this session, and `terraform destroy`/`pulumi destroy`/`cdk destroy` are blocked unless you asked for the specific stack
- Added a warning when the requested model is deprecated or automatically updated to a newer model, shown on stderr in print mode (`-p`) and now also covering models set in agent frontmatter
- Added `attribution.sessionUrl` setting to omit the claude.ai session link from commits and PRs in web and Remote Control sessions
- Added `/config --help` to list all available shorthand keys for `/config key=value`
- Changed `/config` toggle behavior: Enter and Space both change the selected setting, and Esc now saves and closes instead of reverting

- Fixed `thinking.disabled.display: Extra inputs are not permitted` 400 errors on subagent spawns and session-title generation for affected configurations
- Fixed WebSearch returning empty results in subagents

- Fixed user-level skills appearing multiple times in slash-command autocomplete when multiple plugins are enabled
- Fixed MCP servers requiring authentication exposing auth-stub tools to the model in headless/SDK mode
- Fixed tmux teammate panes failing to launch when the shell has slow rc-file initialization, and keystrokes typed during agent spawn leaking into the new tmux pane instead of the leader prompt
- Fixed background tasks started by a teammate being killed when the teammate finishes a turn
- Fixed scheduled task and webhook trigger deliveries being treated as keyboard input; they now classify as task notifications and can no longer approve a pending action or set the session title in auto mode
- Fixed focus mode showing "Ran N PostToolUse hooks" timing lines under each response

## 2.1.181

- Added `/config key=value` syntax to set any setting from the prompt (e.g. `/config thinking=false`) — works in interactive, `-p`, and Remote Control
- Added `sandbox.allowAppleEvents` opt-in setting that lets sandboxed commands send Apple Events on macOS
- Added `CLAUDE_CLIENT_PRESENCE_FILE` environment variable: point it at a marker file to suppress mobile push notifications while you're at the machine

- Improved streaming of long paragraphs: text now appears line-by-line instead of waiting for the first line break
- Improved auto-retry: API connection drops mid-thinking now automatically retry instead of showing "Connection closed while thinking"

- Improved the MCP OAuth browser page to match Claude Code's visual style and auto-close on success
- Changed fullscreen mode URL opening to require Cmd+click (macOS) / Ctrl+click, matching native terminal behavior
- Changed the `Improved N memories` line to no longer list individual files outside verbose mode

- Fixed `open`, `osascript`, and browser-based auth flows failing with error -600 on macOS by adding the Apple Events entitlement
- Fixed a startup regression (~120ms per launch in fresh environments, introduced in 2.1.169): the first prompt no longer waits for the managed-settings fetch when no MCP servers are configured

- Fixed startup crash (`TypeError: Cannot read properties of null`) when `.claude.json` contains corrupted null project entries
- Fixed macOS TUI freezing at session start (Ctrl+C unresponsive) when Spotlight is busy reindexing
- Fixed long-running idle sessions losing their history when another Claude Code process ran the 30-day transcript cleanup
- Fixed foreground subagents spawning unbounded nested chains; they now respect the same 5-level depth limit as background subagents
- Fixed `/recap` and conversation forks using the previous model immediately after a model switch
- Fixed subagent "Thinking" duration showing the parent agent's elapsed time instead of the subagent's own
- Fixed subagents blocked on a nested agent showing a ticking elapsed time instead of "waiting" in the agent panel
- Fixed the API retry indicator ("Retrying in 0s · attempt N/10") staying on screen after the retry succeeded
- Fixed AWS `awsCredentialExport` credentials with a short remaining lifetime causing credential refreshes every minute, and now accepts the JSON shape from `aws configure export-credentials`
- Fixed `claude mcp get`/`list` showing `✓ Connected` when tools/list fails; they now show `! Connected · tools fetch failed` with the error detail
- Fixed `/remote-control` leaving a stale "connecting…" line; it now confirms in the transcript once connected
- Fixed ExitWorktree refusing to remove a clean worktree with "Could not verify worktree state" when bare `git` cannot be resolved on Windows
- Fixed settings changes (such as `/effort` or `/model`) failing with ENOENT when `~/.claude/settings.json` is a relative symlink under a symlinked `~/.claude`

- Fixed mouse-wheel scrolling in WSL2 under Windows Terminal and VS Code (regression in 2.1.172)
- Fixed a sandbox `denyRead`/`allowRead` glob over a large directory tree making the Bash tool description enormous and the session unusable on Linux

- Fixed clicking the prompt input not returning focus from the subagent/footer panel
- Fixed remote session background tasks appearing stuck as "still running" between turns
- Improved plugin loading performance in remote sessions

## 2.1.178

- Agent teams: removed the `TeamCreate` and `TeamDelete` tools. With `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1` set, every session now has one implicit team — spawn teammates directly with the Agent tool's `name` parameter, no setup step needed. The `team_name` parameter on the Agent tool is still accepted but ignored.
- Added `Tool(param:value)` syntax for permission rules to match a tool's input parameters (with `*` wildcard), e.g. `Agent(model:opus)` to block Opus subagents
- Skills in nested `.claude/skills` directories now load when working on files there; on a name clash, the nested skill appears as `<dir>:<name>` so both stay available
- Nested `.claude/` directories: the agent, workflow, and output-style closest to the working directory now wins when names collide; project-scope workflow saves now target the closest existing `.claude/workflows/`
- Improved auto mode: subagent spawns are now evaluated by the classifier before launch, closing a gap where a subagent could request a blocked action without review
- Improved `/doctor` with consistent flat tree layout across all sections, clearer section status icons, and highlighted command names
- Improved the skill listing truncation warning to show how many skill descriptions are affected
- Changed the workflow prompt keyword to use a purple shimmer highlight and trigger only on explicit phrases like "run a workflow" or "workflow:", not on any mention of the word
- Improved Remote Control error messages: connection failures now show a persistent red "/rc failed" indicator in the footer, and the "not yet enabled" error now explains whether it's a gate, a check failure, stale entitlement, or org policy
- `/bug` now requires a description before submitting, and no longer uses model-refusal text as the GitHub issue title
- Fixed a crash (out-of-memory) when the CLI inherits a stale websocket/OAuth file-descriptor environment variable from a parent process
- Fixed Claude in Chrome silently failing to connect when the OAuth token belongs to a different account than the Claude Code login
- Fixed nested `.claude/skills` skills with directory-qualified names being blocked by permission prompts in non-interactive runs
- Fixed several subagent issues: viewing a subagent's transcript now shows tool results and live progress, messages sent while it finishes its turn are no longer dropped, and backgrounding a running subagent (ctrl+b) no longer restarts it from scratch
- Fixed `claude agents` workers failing with `401 Invalid bearer token` when the daemon was started from a shell with a custom API gateway via `ANTHROPIC_BASE_URL` and `ANTHROPIC_AUTH_TOKEN`
- Fixed compaction not honoring `--fallback-model`: compaction now falls back to the configured fallback model chain on overload or model-availability errors
- Fixed model requests continuing to fail with auth errors after credentials were refreshed outside the session, due to a stale cached request configuration
- Fixed background sessions created with `/bg` or `←←` after a turn finished showing "Working" forever in the agents list
- Fixed Linux sandbox failing to start when `.claude/skills` or `.claude/hooks` is a symlink
- Fixed `CLAUDE_CODE_PLUGIN_KEEP_MARKETPLACE_ON_FAILURE=1` preventing fresh marketplace installs from cloning
- Fixed MCP server-level specs (`mcp__server`, `mcp__server__*`, `mcp__*`) in subagent `disallowedTools` being silently ignored
- Fixed vim mode undo: `u` now steps through NORMAL/VISUAL-mode commands one at a time instead of merging commands in quick succession into a single undo step
- Fixed statusline links with custom URI schemes (e.g. `vscode://`) not opening when clicked in `claude agents`
- [VSCode] Fixed pressing Esc to dismiss a CJK IME candidate window canceling the running Claude task

## 2.1.176

- Session titles are now generated in the language of your conversation (set the `language` setting to pin a specific language)
- Added `footerLinksRegexes` setting for regex-matched link badges in the footer row, configurable via user or managed settings
- Improved Bedrock credential caching: credentials from `awsCredentialExport` are now cached until their `Expiration` instead of a fixed 1 hour
- Fixed `availableModels` enforcement: alias model picks can no longer be redirected to a blocked model via `ANTHROPIC_DEFAULT_*_MODEL` environment variables, and `/fast` now refuses to toggle when it would switch to a model outside the allowlist
- Fixed auto mode failing on Fable 5 for organizations without Opus 4.8 enabled — the classifier now falls back to the best available Opus model
- Fixed hook `if` conditions for Read/Edit/Write tool paths: documented patterns like `Edit(src/**)`, `Read(~/.ssh/**)`, and `Read(.env)` now match correctly
- Fixed Linux sandbox failing to start when `.claude/settings.json` is a symlink with an absolute target
- Fixed `/copy` and mouse-selection copy not reaching the system clipboard inside tmux over SSH, and tmux paste buffer not loading on versions older than 3.2
- Fixed Remote Control connecting from web/mobile silently switching the session's model
- Fixed Remote Control disconnect notifications showing a bare numeric code instead of a human-readable reason, and connection failures adding a duplicate line to the conversation transcript
- Fixed Remote Control sessions not disconnecting when you sign in to a different account
- Fixed `/cd` and worktree moves leaving the session reporting the previous directory's git branch
- Fixed `claude agents`: pressing back in one window no longer detaches other windows attached to the same session
- Fixed backgrounded sessions showing "Working" forever when `/bg` mid-turn had nothing left to continue
- Fixed background agent search by PR URL: PRs opened during scheduled wakeups or while a job was blocked now appear in `claude agents` search

- Fixed `claude --bg -cn <name>` not seeding the session name
- Fixed background sessions to neutralize Windows network paths in persisted state before respawn
- Fixed background-session respawn rejecting malformed resume IDs from corrupted state files
- Fixed the Windows background-service daemon not starting when `~/.claude/daemon` has the ReadOnly attribute set
- Fixed cloud sessions failing with "Could not resolve authentication method" when idle for too long before being claimed
- Background sessions now show clearer guidance when a window left open across an auto-update can't submit a reply, and `claude daemon status` explains version-skew behavior

## 2.1.175

- Added `enforceAvailableModels` managed setting — when enabled, the `availableModels` allowlist also constrains the Default model (a Default that would resolve to a disallowed model now falls back to the first allowed model), and user or project settings can no longer widen a managed `availableModels` list

## 2.1.174

- Added `wheelScrollAccelerationEnabled` setting to disable mouse-wheel scroll acceleration in fullscreen mode
- Fixed the `/model` picker hiding the model family that Default resolves to — Opus now appears as its own row on Max/Team Premium/Enterprise plans, Sonnet on Pro/Team plans, and Opus on pay-as-you-go API accounts
- Fixed `/model` picker showing a hardcoded Sonnet version label when `ANTHROPIC_DEFAULT_SONNET_MODEL` pins a different Sonnet
- Fixed the "Fable 5 is now consuming usage credits" banner incorrectly showing for enterprise accounts with usage-based billing
- Fixed Bedrock GovCloud regions (`us-gov-*`) deriving the wrong inference profile prefix (`global` instead of `us-gov`), causing 400 errors on derived model IDs
- Fixed background sessions inheriting another session's `ANTHROPIC_*` provider env (gateway URL, custom headers, `/model` aliases) from the shell that started the background daemon
- Fixed a 1-2 second pause when exiting Claude Code shortly after a shell command was interrupted or killed on macOS and Linux
- Fixed git commit co-author attribution showing an incorrect model name for some models
- Fixed the `/advisor` dialog pre-selecting a saved advisor model that is blocked by the `availableModels` allowlist
- Fixed skill hot-reload re-sending the entire skill listing when a single skill changed; only changed skills are now re-announced
- Fixed Workflow tool `agent()` subagents missing per-agent attribution headers
- [VSCode] Added usage attribution to the Account & usage dialog (`/usage`) showing cache misses, long context, subagents, and per-skill/agent/plugin/MCP breakdowns over the last 24h or 7d
- Fixed pre-warmed background workers failing with "Could not resolve authentication method" when claimed after sitting idle

## 2.1.173

- Fixed Fable 5 model names with a `[1m]` suffix not being normalized — Fable 5 includes 1M context by default, so the suffix is now stripped automatically
- Fixed a spurious "sandbox dependencies missing" startup warning on Windows when sandbox was enabled in settings

## 2.1.172

- Sub-agents can now spawn their own sub-agents (up to 5 levels deep)
- Amazon Bedrock now reads the AWS region from `~/.aws` config files when `AWS_REGION` isn't set, matching AWS SDK precedence; `/status` shows where the region came from
- Added a search bar when browsing a marketplace's plugins in `/plugin`
- Added `model` attribute to the `claude_code.lines_of_code.count` OTEL metric
- Fixed sessions using 1M context without usage credits getting permanently stuck — the session now automatically compacts back under the standard context limit
- Fixed a repeating "an image in the conversation could not be processed and was removed" error when the conversation contained multiple images
- Fixed the agents view keeping a session under Working with a busy spinner for up to 30 seconds after the worker replied

- Fixed background-session attach failing with EAUTH for sessions started on an older version after the daemon auto-updated
- Fixed a background sub-agent staying stuck as "active" in the agent panel after a nested agent it spawned was stopped
- Fixed `/model` suggestions in the `claude agents` dispatch input rendering with a misleading slash prefix and showing models disabled for your org
- Fixed `availableModels` restrictions not being applied to subagent model overrides, the agent dispatch model picker, and the advisor model
- Fixed `availableModels` allowlists hiding the `/model` picker's Opus and Sonnet 1M rows when entries use version-specific IDs like `claude-opus-4-8`
- Fixed the `/model` picker on Bedrock offering models the provider doesn't serve — selecting one silently switched the session model and lit the selection marker on multiple rows
- Fixed model IDs getting a doubled 1M-context suffix (e.g. `[1M][1m]`) when `ANTHROPIC_DEFAULT_OPUS_MODEL` already includes one
- Fixed `opusplan` model setting not shipping with 1M context in plan mode for entitled users; the `opusplan[1m]` workaround now also correctly switches to Opus in plan mode
- Fixed `WebFetch(domain:*.example.com)` wildcard domain rules never matching subdomains in allow, deny, and ask position, and file permission rules with mid-pattern wildcards (e.g. `Read(secrets-*/config.json)`) being rejected at startup
- Fixed up-arrow prompt history showing the main agent's prompts while a subagent's chat tab is open
- Fixed memory recall not finding mounted team memory stores (`CLAUDE_MEMORY_STORES`) in remote sessions
- Fixed workflow validation rejecting scripts whose prompt strings or comments merely mention `Date.now()`/`Math.random()`
- Disable mouse tracking on Windows consoles that don't fully support it
- Fixed the `/plugin` marketplace list losing its cursor after backing out of a long plugin list, and Esc from the plugin browser returning to the wrong tab
- Improved performance in long conversations by removing redundant message normalization and avoiding full message-history transforms when streaming tool-use state is unchanged
- Reduced idle CPU usage: `/goal` status chip no longer re-renders the terminal at 5 Hz while idle, and fewer UI re-renders while subagents run in parallel
- Improved Claude in Chrome tool loading: browser tools now load in a single batched call instead of one per tool
- Improved the non-interactive Usage Policy refusal message to suggest starting a new session or changing your model
- `/code-review` now keeps the `ultra` option visible when you're not signed in to claude.ai, with an explanation that the cloud review requires a claude.ai account
- Shortened the Remote Control footer indicator to "/rc active" and hid it on narrow terminals
- Stopped promoting `/loop` in remote sessions, where pending loops don't keep the container alive
- [VSCode] Fixed PowerShell tool calls rendering as raw JSON instead of a proper command display and permission dialog, and stripped ANSI escape codes from displayed shell output

## 2.1.170

- Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use. Fable’s capabilities exceed those of any model we’ve ever made generally available. Update to version 2.1.170 for access. https://www.anthropic.com/news/claude-fable-5-mythos-5
- Fixed sessions not saving transcripts (and not appearing in --resume) when launched from the VS Code integrated terminal or any shell that inherited Claude Code environment variables.

## 2.1.169

- Added `--safe-mode` flag (and `CLAUDE_CODE_SAFE_MODE`) to start Claude Code with all customizations (CLAUDE.md, plugins, skills, hooks, MCP servers) disabled for troubleshooting
- Added `/cd` command to move a session to a new working directory without breaking the prompt cache mid-session
- Added a `disableBundledSkills` setting and `CLAUDE_CODE_DISABLE_BUNDLED_SKILLS` environment variable to hide bundled skills, workflows, and built-in slash commands from the model
- Fixed Up/Down arrows jumping to command history past the wrapped rows of a long input line — they now move through each visual row first, and history recall enters at the near edge
- Fixed enterprise managed MCP policies (`allowedMcpServers`/`deniedMcpServers`) not being enforced on reconnect, IDE-typed configs, `--mcp-config` servers during the first session after install, or before remote settings loaded; also fixed slow cold starts for orgs without remote settings
- Fixed a ~30-50ms UI stall at the start of each turn for macOS users logged in with claude.ai credentials
- Fixed `claude -p` being slow or appearing to hang on Windows while waiting for the slash-command/skill scan (regression in 2.1.161)
- Fixed Remote Control getting stuck on "reconnecting" after resuming a session when an OAuth token refresh happened at the same time
- Fixed Git Credential Manager's "Connect to GitHub" popup appearing on Windows at startup when background git commands ran without cached credentials
- Fixed footer hints (e.g. "esc to interrupt") not showing for users with a custom statusline
- Fixed stale permission and dialog prompts reappearing every time you reattached to a remote session whose worker had died while waiting on them
- Fixed `claude agents --json` omitting blocked and just-dispatched background sessions; added `--all` to include completed sessions, plus new `id` and `state` fields
- Fixed agents view leaving a stale/garbled frame after navigating back from an agent on WSL in Windows Terminal
- Fixed background agents ignoring project-level settings `env` values (e.g. `ANTHROPIC_MODEL`) when dispatched onto a pre-warmed worker
- Fixed MCPB plugin cache being spuriously invalidated on Windows, causing unnecessary re-extraction
- Fixed plugin `.in_use` PID lock files accumulating without bound; stale markers from crashed sessions are now swept once per day
- Fixed untrusted project settings being able to set OTEL client-certificate paths without trust confirmation
- `/workflows` now opens immediately even while a turn is in progress
- Improved `TaskCreate` reliability: malformed inputs are repaired automatically and validation errors for unloaded tools include the schema
- Improved the error message shown when your organization has disabled API key authentication, with guidance based on where the active API key comes from
- Reduced CPU usage while responses stream and during spinner animations
- Restored a default 5-minute idle timeout on Vertex/Foundry so a stalled stream aborts instead of hanging indefinitely; set `API_FORCE_IDLE_TIMEOUT=0` to opt out
- Remote-managed settings with an invalid entry now apply their remaining valid policies and surface the validation error, instead of silently dropping the whole payload
- Background sessions now preserve `--ide`, `--chrome`, `--bare`, `--remote-control`, and other flags across retire→wake, and respawn state validation was hardened
- Background sessions are now told that shared-checkout edits are blocked until they enter a worktree, avoiding a wasted rejected edit before `EnterWorktree`
- The "CLAUDE.md is too long" warning threshold now scales with the model's context window
- Auto-updater on Windows now stops retrying within a session once `claude.exe` is held by another process
- Improved color contrast for skill tags in the slash-command menu
- Promo credit claims for Apple/Google-billed subscribers without a payment method now explain where to add one
- Added a tip suggesting `claude agents` when running multiple concurrent sessions

## 2.1.168

- Bug fixes and reliability improvements

## 2.1.167

- Bug fixes and reliability improvements

## 2.1.166

- Added `fallbackModel` setting to configure up to three fallback models tried in order when the primary model is overloaded or unavailable; `--fallback-model` now also applies to interactive sessions
- Added glob pattern support in deny rule tool-name position (`"*"` denies all tools); allow rules reject non-MCP globs, and unknown tool names in deny rules warn at startup
- Hardened cross-session messaging: messages relayed via `SendMessage` from other Claude sessions no longer carry user authority — receivers refuse relayed permission requests, and auto mode blocks them
- `MAX_THINKING_TOKENS=0`, `--thinking disabled`, and the per-model thinking toggle now disable thinking on models that think by default via the Claude API (3P providers unchanged)
- Claude Code now retries a turn once on the fallback model when the API rejects an unexpected non-retryable error; auth, rate-limit, request-size, and transport errors still surface immediately
- `claude update` now announces the target version before downloading instead of going silent
- `claude agents`: typing a URL into the list now filters to the session whose first prompt contained it
- Fixed a recurring "image could not be processed" error and extra token usage when an unprocessable image was sent in a session
- Fixed remote sessions becoming permanently stuck when a brief backend disruption occurred during worker registration at startup
- Fixed flickering in JetBrains IDE terminals (IntelliJ, PyCharm, WebStorm, etc.) on 2026.1+ by enabling synchronized output
- Fixed Shift+non-ASCII characters (e.g. Shift+ä → Ä) being dropped in terminals using the Kitty keyboard protocol (WezTerm, Ghostty, kitty)
- Fixed PowerShell command validation occasionally hanging far past its time budget on Windows when a killed process's children held its output pipes
- Fixed orphaned `claude --bg-pty-host` processes spinning at 100% CPU after the daemon dies while connected on macOS
- Fixed voice mode requiring `/login` to clear a stale auth check after toggling `/voice`
- Fixed managed settings with an invalid entry silently disabling enforcement of their remaining valid policies
- Fixed managed-settings `allowedMcpServers`/`deniedMcpServers` predicates not matching when they use `${VAR}` references
- Fixed background agent sessions that entered a git worktree crash-looping with "No conversation found" when reopened from `claude agents`
- Fixed duplicated thinking text in the Ctrl+O transcript view while streaming
- Fixed `/doctor` showing a contradictory failed "Not inside a remote session" check when run inside a remote session
- Fixed the cursor sticking at the end of the first line when typing a multiline prompt in the `claude agents` dispatch and reply inputs
- Fixed blank lines appearing between background agent rows in the task list on terminals without Unicode support

## 2.1.165

- Bug fixes and reliability improvements

## 2.1.163

- Added `requiredMinimumVersion` and `requiredMaximumVersion` managed settings — Claude Code refuses to start if its version is outside the allowed range and directs the user to an approved version
- Added `/plugin list` command to list installed plugins, with `--enabled`/`--disabled` filters
- Added a "c to copy" shortcut to `/btw` that copies the raw markdown answer to the clipboard, preserving formatting when pasted elsewhere
- Hooks: Stop and SubagentStop hooks can now return `hookSpecificOutput.additionalContext` to give Claude feedback and keep the turn going without being labeled a hook error
- Skills: added `\$` escape syntax to include a literal `$` before a digit in command bodies
- stdio MCP servers now receive the same `CLAUDE_CODE_SESSION_ID` as hooks/Bash on `--resume`
- Fixed `claude -p` hanging forever after its final result when a backgrounded command never exits — background shells are now stopped ~5s after the result once stdin closes
- Fixed `claude -p` failing with "ANTHROPIC_API_KEY required" on Bedrock/Vertex/Foundry when `CI=true` and no Anthropic API key is set
- Fixed bash commands failing under bazel and EDR-protected Go workflows: `$TMPDIR` was overridden to `/tmp/claude-{uid}` for all commands instead of only sandboxed ones (regression in 2.1.154)
- Fixed Bash commands failing on Windows with "EEXIST: file already exists" on the session-env directory when it has the read-only attribute or is inside OneDrive
- Fixed org-managed permission rules not applying for the entire session when the managed settings fetch completed during startup on a fresh config directory
- Fixed background sessions in `claude agents` losing their running background tasks when reattached after a Claude Code update
- Fixed terminal misalignment and a multi-second hang when exiting the agent view by pressing Esc
- Fixed clicking Stop on a background-task chip in the desktop app not clearing the chip when the underlying process was already gone
- Fixed keyboard input becoming permanently unresponsive after a paste operation whose end marker is dropped by the terminal
- Fixed hook `if: "Bash(...)"` conditions firing on every Bash command containing `$()` or `$VAR`; the pattern now matches against commands inside subshells and backticks too
- Fixed deny rules on home-directory paths (e.g. `Read(~/Desktop/**)`) not blocking Bash commands that reference the path via `$HOME`
- Fixed a stray "(no content)" line left in the transcript after closing panel dialogs like /mcp and /plugins
- Background agent sessions now update to a new Claude Code version in the background, so opening a session after an update no longer waits on a cold restart
- Clearer descriptions for built-in commands and skills in the / menu
- The subscription-switch suggestion now shows in the startup announcement slot instead of a toast
- `claude agents` dispatching from the state-grouped view now starts the session in the directory the agent view was opened from

## 2.1.162

- `claude agents --json` now includes `waitingFor` showing what a waiting session is blocked on (e.g. permission prompt)
- `--tools`: explicitly listing Grep/Glob now provides the dedicated search tools on native builds with embedded search (previously these names were silently ignored)
- `/effort` now confirms when your chosen level will persist as the default for new sessions
- Clicking a slash command in the autocomplete menu now fills it into your prompt instead of running it immediately; press Enter to run
- Remote Control now shows as a persistent footer pill (with a link to the session) instead of a startup message
- Renamed Windsurf to Devin Desktop in the `/ide` menu, `/terminal-setup`, and `/scroll-speed`, following the editor's rebrand
- Fixed a silent startup hang when the config directory is read-only or unwritable — Claude Code now starts with in-memory config and surfaces startup errors instead of showing a blank screen
- Fixed WebFetch permission rules not being applied to built-in preapproved domains; explicit `WebFetch(domain:...)` deny/ask/allow rules now take precedence over the preapproved-host auto-allow
- Fixed Windows permission rules never matching when spelled with backslashes (`~\`, `\\server\share`) or case-variant paths, and Read deny rules not hiding files from Glob/Grep results
- Fixed an interrupt (Esc) sent at the very start of a turn being silently dropped in stream-json/SDK sessions, leaving the turn running with no "Interrupted" feedback
- Fixed API 400 `no low surrogate in string` errors for classifier side-queries and MCP server descriptions containing emoji near a truncation boundary
- Fixed MCP per-server `timeout` config values below 1000 ms being floored to a 1-second watchdog that aborted every tool call; sub-1000 ms values are now ignored (falling back to `MCP_TOOL_TIMEOUT` or default), and `claude mcp get` annotates them accordingly
- Fixed the LSP tool's `workspaceSymbol` operation returning no results; it now accepts a `query` parameter and passes it to the language server
- Fixed `claude agents` cutting live status text (tool args, replies, prompts, exec output) at 60–120 columns on wide terminals; the status detail now uses the full terminal width
- Fixed `claude agents` truncating long session names at 40 columns; the name column now grows with terminal width
- Fixed `claude agents` attach occasionally bouncing straight back to the session list on the first try after a background-service restart
- Fixed `claude agents` Ctrl+V image paste doing nothing in the dispatch input and the session reply box; pasting with no image now shows a hint
- Fixed backgrounding a session with ← silently losing the conversation when the background service cannot start; the session stays in the list as a failed row you can wake with Enter
- Fixed replies from the agents view that fail to send being lost; they are now queued for delivery on the next session start
- Fixed cross-session messaging (`SendMessage`) silently breaking when `CLAUDE_CODE_TMPDIR` or `$TMPDIR` points at a deep directory
- Fixed opening a running background session from `claude agents` stalling for 5 seconds before attaching
- Quieter startup: notices group by severity, and session info and announcements share a single line per launch
- Startup warnings rewritten to be shorter and clearer, each with a concrete fix
- Launch-prompt warnings (deep link/pre-filled prompt) now stay pinned below the input until you act instead of scrolling away
- Failed turns now show a compact warning line instead of a multi-line red error block
- Improved background service startup and `claude update` verification to wait out endpoint-security scanning of new binaries instead of failing after 5 seconds
- Background dispatch spawn failures now report the error class name when no errno is available
- Removed the "Claude in Chrome enabled" and "marketplace installed" startup messages; model auto-updates and the team-onboarding tip now show as quiet notices under the logo

## 2.1.161

- `OTEL_RESOURCE_ATTRIBUTES` values are now included as labels on metric datapoints, so you can slice usage metrics by custom dimensions like team or repo
- `claude agents` rows now show `done/total` before the detail when work is fanned out; peek shows the longest-running item
- `/mcp` now collapses claude.ai connectors you've never signed in to behind a "Show unused connectors" row
- Parallel tool calls: a failed Bash command no longer cancels other calls in the same batch — each tool returns its own result independently
- Fullscreen mode: clipboard now uses `wl-copy`/`xclip`/`xsel` on Linux when available, copies to both the clipboard and PRIMARY selection for middle-click paste, and the "hold {key} for native selection" hint now shows the correct key per terminal
- Fixed the `/effort` dialog, workflow animations, and prompt keyword shimmer not honoring the "Reduce motion" setting
- Fixed `forceLoginOrgUUID`/`forceLoginMethod` managed-settings policies blocking third-party provider sessions (Bedrock, Vertex, Foundry, Mantle) alongside the org pin (regression in 2.1.146)
- Fixed background subagent output corrupting `claude -p` stdout when using `--output-format text` or `json`
- Fixed `/usage-credits` starting a re-login for Team and Enterprise admins instead of pointing to the organization's usage settings page
- Fixed `/autofix-pr` reporting "cannot run on the default branch" when the session is inside a git worktree or another repository
- Fixed `--resume` picker not showing sessions from the current directory when it isn't a git worktree (e.g., jj workspaces)
- Fixed Windows hooks that invoke bash explicitly (e.g., `/usr/bin/bash script.sh`) failing with "command not found" or "cannot execute binary file"
- Fixed OpenTelemetry log events (`user_prompt`, `api_request`, `tool_result`, `tool_decision`) being silently dropped when emitted before telemetry initialization completed
- Fixed `claude mcp` list/get/add printing secrets to the terminal: `${VAR}` references are no longer expanded, and credential headers and URL secrets are redacted
- Fixed Workflow agents spawned with `isolation: "worktree"` in background sessions being blocked from editing files inside their own worktree
- Fixed background sessions dispatched from `claude agents` booting on a stale model from the daemon's environment instead of the model in `settings.json`
- Fixed a potential crash when rendering Write tool results after resuming a session
- Fixed completed subagents getting stuck showing as running when an error occurs while finalizing their result
- Fixed `EADDRINUSE` errors from tools that bind Unix sockets under `$TMPDIR` when `CLAUDE_CODE_TMPDIR` is set to a deep path
- Improved terminal rendering performance by stabilizing the layout engine's JIT compilation profile
- Improved rendering performance for large file writes
- [VSCode] Added a tip suggesting disabling terminal GPU acceleration (or running `/terminal-setup`) to fix garbled glyphs

## 2.1.160

- Added a prompt before writing to shell startup files (`.zshenv`, `.zlogin`, `.bash_login`) and `~/.config/git/`, which could otherwise lead to unintended command execution
- `acceptEdits` mode now prompts before writing build-tool config files that grant code execution (`.npmrc`, `.yarnrc*`, `bunfig.toml`, `.bazelrc`, `.pre-commit-config.yaml`, `.devcontainer/`, etc.)
- Edit no longer requires a separate Read after viewing a file with `grep`: single-file `grep`/`egrep`/`fgrep` commands now satisfy the read-before-edit check
- Fixed copy-on-select not writing to the Windows clipboard on WSL — now uses PowerShell interop instead of OSC 52, which terminals like MobaXterm don't support
- Fixed restoring a completed session from `claude agents` dropping chat history and re-running the original prompt
- Fixed background sessions re-attached after overnight retire losing their conversation and re-running the original prompt

- Fixed valid `file:///C:/...` links being rewritten to a broken path on Windows terminals with hyperlink support
- Fixed voice mode failing to connect when the project directory or branch name contains non-ASCII or special characters
- Fixed the auto mode unavailability message on third-party providers (Bedrock/Vertex/Foundry) to point to the `CLAUDE_CODE_ENABLE_AUTO_MODE` opt-in instead of incorrectly blaming the model
- Fixed `/effort ultracode` incorrectly blaming the dynamic workflows setting when the model cannot run xhigh; ultracode is no longer offered on models that do not support it

- Fixed Claude's past replies disappearing from scrollback when resuming a brief mode session with brief mode turned off
- Fixed vim mode `p` pasting on the line below instead of at the cursor when the register was yanked with `v$`
- Improved performance of opening recently-inactive background agent sessions in `claude agents`
- Improved auto mode classifier latency by reducing reasoning on routine actions, lowering the chance of "could not evaluate this action" blocks
- Improved background-session teardown (`claude rm`/`stop`, idle reap) to send SIGTERM to running shell subprocesses before SIGKILL, so cleanup handlers run
- Removed `CLAUDE_CODE_OPUS_4_6_FAST_MODE_OVERRIDE`; the environment variable is now a no-op
- Removed the JetBrains plugin install suggestion from startup
- Renamed the dynamic-workflow trigger keyword from `workflow` to `ultracode`. The word "workflow" no longer triggers a run; asking for one in your own words still works. The trigger keyword is highlighted in violet in the prompt input

## 2.1.159

- Internal infrastructure improvements (no user-facing changes)

## 2.1.158

- Fixed the `--resume` session picker leaving its contents on the terminal after exiting in fullscreen mode
- Fixed `--worktree` and `--worktree --tmux` returning to the canonical repo root instead of the current linked worktree
- Fixed the `/model` picker showing an incorrect "Newer version available" hint when the selected model is already the newest in its family; the pinned-model row now shows the model's description instead of its raw ID
- Fixed literal markdown markers (backticks, asterisks) appearing in the in-progress message text in fullscreen mode
- Fixed the terminal freezing after approving the managed-settings security dialog at startup
- Fixed a rare duplicate line appearing in scrollback after the terminal UI redraws

## 2.1.154

- Opus 4.8 is here! Now defaults to high effort · /effort xhigh for your hardest tasks
- Introducing dynamic workflows: ask Claude to create a workflow and it orchestrates work across tens to hundreds of agents in the background, so you can take on larger, more complex tasks. Run `/workflows` to view your runs

- Renamed the `/effort` slider labels from "Speed"/"Intelligence" to "Faster"/"Smarter" for clarity
- `claude agents`: type `! <command>` to run a shell command as a background session you can attach to and detach from. Also available as `claude --bg --exec '<command>'`
- `claude agents`: `/logout` now signs you out instead of being sent to a background session
- `←←` to open the agents view now works on Bedrock, Vertex, Foundry, and with telemetry disabled
- Claude in Chrome: pick which connected browser to use via `/chrome` → "Select browser…", or in-chat when a browser action runs with multiple connected
- Plugins can now declare `defaultEnabled: false` in `plugin.json` or a marketplace entry; enable them with `/plugin` or `claude plugin enable`. Dependencies of enabled plugins are still enabled automatically
- The `/plugin` Discover tab now pins plugins whose relevance signals match the current directory with a "suggested for this directory" annotation

- Added Claude Opus 4.8 support and 4.7 → 4.8 migration guidance to the `/claude-api` skill
- Deprecated `CLAUDE_CODE_OPUS_4_6_FAST_MODE_OVERRIDE` (will be removed on 06/01). To use fast mode on Opus 4.6, switch with `/model claude-opus-4-6[1m]` and then `/fast on`
- Improved the auto-mode classifier's detection of data exfiltration, particularly bulk transfers of repository contents
- Fixed `rm -rf $HOME` not being blocked as a dangerous path when `HOME` has a trailing slash

- Fixed orphaned `claude --bg-pty-host` processes spinning at 100% CPU after the daemon exits on macOS
- Fixed number key shortcuts not working for options shown below the divider in option dialogs
- Fixed `worktree.baseRef: "head"` resolving to the main checkout's HEAD instead of the current worktree's HEAD when spawning subagents or calling `EnterWorktree` from inside a linked worktree

- Fixed a single invalid `allowedMcpServers`/`deniedMcpServers` entry in managed settings discarding all managed-settings policy; the bad entry is now dropped with a `claude doctor` warning
- Fixed API 400 errors on models that don't support the effort parameter when `CLAUDE_CODE_ALWAYS_ENABLE_EFFORT` is set
- Windows: Fixed update failures caused by `claude.exe` being in use showing a generic error instead of telling you to close other sessions and retry

- [VSCode] Auto mode no longer requires the bypass-permissions setting to appear in the mode picker, and a dismissable notice on the new-session screen explains auto mode the first time it's active
- Fixed the task panel below the prompt showing a stray unselectable "main" row when only a workflow is running
- Fixed /mcp tools list and tool detail rendering when MCP servers have long or multi-line tool names or long descriptions

- Fixed `claude --help` rendering unwrapped output on terminals narrower than 92 columns
- Fixed MCP tool progress notifications not rendering in the collapsed tool view
- Fixed `Agent` tool with `subagent_type: 'claude'` running in an undocumented temporary worktree, which could silently discard outputs written to gitignored paths
- `/bg` while Claude is responding now continues the response in the background session instead of dropping it
- Fixed `/btw` keyboard shortcuts becoming unresponsive in background sessions while a task is running
- Fixed background sessions writing temp files to `$CLAUDE_JOB_DIR` triggering a "sensitive file" permission prompt

- Fixed opening `claude agents` with Remote Control enabled leaving zombie session entries on the Code tab after exiting
- Fixed `/rename` in background sessions not updating the session banner immediately
- Fixed Windows update rollback: if a Windows update fails, Claude Code now restores the original executable by copy and tells you how to recover
- [VSCode] Fixed Claude Code processes not shutting down cleanly when VS Code closed on Windows, causing false "unclean exit" reports and orphaned MCP servers

- If you customized the `modelPicker:setAsDefault` keybinding, rename it to `modelPicker:thisSessionOnly` in keybindings.json (the `d` action was replaced by `s`)

## 2.1.152

- `/code-review --fix` now applies review findings to your working tree after the review, surfacing reuse, simplification, and efficiency suggestions; `/simplify` now invokes `/code-review --fix`
- Skills and slash commands can now set `disallowed-tools` in frontmatter to remove tools from the model while the skill is active
- Added `/reload-skills` command to re-scan skill directories without restarting the session
- `SessionStart` hooks can now return `reloadSkills: true` to re-scan skill directories, making skills installed by the hook available in the same session

- Claude Code now switches to your configured `--fallback-model` for the rest of the session when the primary model is not found, instead of failing every request
- Auto mode no longer requires opt-in consent
- Vim mode: `/` in NORMAL mode now opens reverse history search (like Ctrl+R), matching bash/zsh vi-mode
- The `/usage` breakdown now includes large session files; files are scanned with a streaming read so memory usage stays flat
- Thinking summaries in the collapsed group now stay readable for at least 3 seconds, render as markdown, and cap at 10 lines (`Ctrl+O` shows the full thinking)
- In fullscreen mode, the "Thinking for Ns" indicator now counts up live while the model is thinking, and keeps its value if you interrupt mid-thought
- Simplified the Workflow tool's inline progress display — live agent counts now show only in the persistent workflow status row below the prompt
- The post-response timer now shows "Waiting for N background agents/workflows to finish" when backgrounded agents or workflows are still running, and reports the cumulative time once their results are processed
- Added the session entrypoint as an OpenTelemetry metric attribute (`app.entrypoint`, opt-in via `OTEL_METRICS_INCLUDE_ENTRYPOINT=true`)
- Fixed terminal styling degrading in very long sessions by recycling the renderer's style pool

- Fixed the effort-change confirmation dialog appearing when the conversation has no messages or when switching between effort levels that resolve to the same underlying value
- Fixed the Agent tool description referencing an agent list that is never delivered when running with `--bare` or with attachments disabled
- Fixed a background worker crash in `claude agents` when accepting a stale permission prompt after a subagent was cancelled
- Fixed `cache_creation_input_tokens` reporting as 0 in transcript and result usage when the API reports cache writes only via the nested `cache_creation` breakdown
- Fixed the PushNotification tool incorrectly reporting "Mobile push not sent (Remote Control inactive)" in SDK-hosted sessions when Remote Control is enabled
- Fixed sessions getting stuck after a model or login switch left stale thinking-block signatures in history; now stripped proactively with a retry safety-net

## 2.1.150

## 2.1.149

- `/usage` now shows a per-category breakdown of what's driving your limits usage — skills, subagents, plugins, and per-MCP-server cost

- Markdown output now renders GFM task list checkboxes (`- [ ] todo` / `- [x] done`) instead of plain bullets
- Enterprise: added the `allowAllClaudeAiMcps` managed setting to load claude.ai cloud MCP connectors alongside `managed-mcp.json`
- Fixed a PowerShell permission bypass: built-in `cd` functions (`cd..`, `cd\`, `cd~`, `X:`) changed the working directory undetected, letting a later command read outside the workspace
- Fixed the sandbox write allowlist in git worktrees covering the entire main repository root instead of only the shared `.git` directory (with `hooks/` and `config` denied)
- Fixed PowerShell prefix/wildcard allow rules (e.g. `PowerShell(dotnet.exe build *)`) not pre-approving native executables and scripts
- Fixed a permission-analysis gap where the parser trusted stale variable-tracking values for `PWD`/`OLDPWD`/`DIRSTACK` across `cd`/`pushd`/`popd`

- Fixed a race where a just-submitted prompt could appear twice in the up-arrow history
- Fixed tapping the "Jump to bottom" pill in fullscreen mode not dismissing it immediately
- Improved `/feedback` reports to include the conversation that happened before context compaction, making issues from earlier in long sessions easier to triage

## 2.1.148

- Fixed the Bash tool returning exit code 127 on every command for some users (a regression introduced in 2.1.147)

## 2.1.147

- Pinned background sessions (`Ctrl+T` in `claude agents`) now stay alive when idle, are restarted in place to apply Claude Code updates, and are shed under memory pressure only after non-pinned sessions
- Renamed `/simplify` to `/code-review`. It now reports correctness bugs at a chosen effort level (e.g., `/code-review high`); pass `--comment` to post findings as inline GitHub PR comments. The old cleanup-and-fix behavior has been removed
- Improved auto-updater: retries transient network failures, reports specific error categories and OS error codes on failure, and shows the current version when an update fails
- Improved diff rendering performance for large file edits
- Prompt history no longer records consecutive duplicate entries — recalling a prompt with arrow-up and submitting it again won't add another copy
- Fixed enterprise login restrictions (`forceLoginOrgUUID` and `forceLoginMethod` managed-settings) not being enforced against third-party-provider and API-key sessions
- Fixed `&` in `!` command output displaying as `&amp;`, which broke copy-pasting URLs from commands like `gcloud auth login` on headless machines
- Fixed unknown slash commands silently doing nothing in headless/SDK mode — they now show an error message
- Fixed `/help` rendering a broken tab header and showing only one command per page on small terminals when not in fullscreen mode
- Fixed shell snapshot dropping user functions whose names start with a single underscore, which broke aliases referencing them
- Fixed plugin agents that declare multiple `Agent(...)` types in `tools:` frontmatter dropping all but the last entry
- Fixed hook `if` conditions like `PowerShell(git push*)` never matching — only `PowerShell(*)` worked

- Fixed `/background` refusing sessions whose only typed input was a skill or custom slash command
- Fixed auto mode suppressing `AskUserQuestion` when the user or a skill explicitly relies on it; the auto-mode classifier now sees the user's answers as intent signal
- Fixed `/theme` "New custom theme" and color editor dialogs not responding to Esc
- Fixed an uncaught exception at the end of streaming sessions when running via the Agent SDK
- Fixed a rare hang when waiting for scroll to settle on Windows

- Fixed backgrounded sessions re-prompting for tool permissions you already granted with "don't ask again"
- Fixed GNOME Terminal right-click and middle-click paste not inserting text
- Fixed `CLAUDE_CODE_SUBAGENT_MODEL` not applying to teammate processes spawned by agent teams

- Fixed stripped images prompting the model to repeatedly re-read media that was no longer present

## 2.1.145

- Added `claude agents --json` to list live Claude sessions as JSON for scripting (tmux-resurrect, status bars, session pickers)
- Added `agent_id` and `parent_agent_id` attributes to `claude_code.tool` OTEL spans, and fixed trace parenting so background subagent spans nest under the dispatching Agent tool span
- Status line JSON input now includes GitHub repo and PR information when detected
- `/plugin` Discover and Browse screens now show a plugin's commands, agents, skills, hooks, and MCP/LSP servers before installation
- `claude agents` terminal tab title now shows the awaiting-input count so an alt-tabbed window tells you when an agent needs attention
- Slash command and @-mention suggestion list now supports mouse hover and click in fullscreen mode
- Stop and SubagentStop hook input now includes `background_tasks` and `session_crons` fields
- Fixed a permission-prompt bypass where bare variable assignments to non-allowlisted environment variables in Bash commands were auto-approved

- Fixed the spinner and elapsed-time display freezing until a keypress after the terminal was resized or refocused
- Fixed the cross-project resume hint failing in default Windows PowerShell 5.1 — Windows now uses `;` as the command separator

- Fixed task lists rendering in random order when several tasks are created at once
- Fixed stale "Failed to install Anthropic marketplace" banner showing when the marketplace is already installed

- Fixed `/review` using a deprecated `projectCards` GraphQL query that errored on repos with Classic Projects
- Fixed `claude plugin validate` not flagging `skills:` entries that point at a file instead of a directory — the error now suggests the parent directory
- Fixed an infinite loop where a skill using `context: fork` could repeatedly re-invoke itself instead of running
- Improved the Read tool to return a truncated first page with a "PARTIAL view" notice instead of a hard error when a whole-file read exceeds the token limit

## 2.1.144

- Added `/resume` support for background sessions — sessions started via `claude --bg` or agent view now appear alongside interactive ones, marked with `bg`
- Added elapsed duration to background subagent completion notifications (e.g. "Agent completed · 3h 2m 5s")
- The `/plugin` browse and discover panes now show when a plugin was last updated
- `/model` now changes the model for the current session only; press `d` in the model picker to set a default for new sessions
- Renamed "extra usage" to "usage credits" across CLI copy; `/extra-usage` is now `/usage-credits` (old name still works)
- Fixed startup hanging up to 75s when `api.anthropic.com` is unreachable (captive portal, firewall, VPN issues) — side-channel API calls now time out after 15s
- Fixed garbled terminal output after a missed window-resize event (e.g. dragging a VS Code split-pane divider) — now self-heals on the next frame instead of requiring Ctrl+L
- Fixed progressive terminal display corruption (stale/garbled glyphs) that could appear in very long sessions and only cleared on terminal resize or restart
- Reduced terminal rendering glitches in VS Code by reducing spinner animation color count
- Fixed macOS background sessions crashing with "exit 1 before init" when the project lives under a Full Disk Access-protected folder (regression in 2.1.143)
- Fixed an unrecoverable conversation when reading a file whose image extension doesn't match its contents (e.g. HTML saved as .png) — now falls back to text
- Fewer spurious tool errors during search: `head`/`tail` file views now satisfy the read-before-edit check, and a "no matches" result (exit code 1) from `egrep`, `fgrep`, `git grep`, or `git diff` is no longer reported as a command failure
- Fixed `/branch` failing with "No conversation to branch" after entering a worktree or in some background sessions
- Fixed pressing Escape in the AskUserQuestion notes field aborting the turn instead of returning to answer selection
- Fixed model selection not applying when changed via the IDE model picker or `applyFlagSettings` after startup

- Fixed Bedrock and Vertex users unable to select "Opus (1M context)" from the `/model` picker (regression in v2.1.129)
- Fixed remote-session login failing with "Can't access this organization" for users with `forceLoginMethod` and `forceLoginOrgUUID` set
- Fixed MCP servers with paginated `tools/list` responses only returning the first page, silently dropping tools
- Fixed MCP images with unsupported MIME types (e.g. SVG) breaking the conversation — now saved to disk and referenced in the tool result
- Fixed file descriptor exhaustion when a build runs inside a skill directory — non-`.md` files no longer trigger skill reloads
- Fixed session title being generated from plugin monitor output instead of the user's first prompt
- Fixed Skill tool failing with permission error in headless mode (regression in v2.1.141)
- Fixed plugins enabled in your own settings showing "not cached" errors after first load on a fresh machine; plugins enabled only by a project's `.claude/settings.json` now show an actionable `claude plugin install` hint
- Fixed `claude mcp list` silently reporting no servers when `.mcp.json` can't be parsed (e.g. using VS Code's `"servers"` key instead of `"mcpServers"`) — now shows configuration errors
- Fixed background side-queries on custom `ANTHROPIC_BASE_URL` setups and Bedrock Mantle not using Haiku — now falls back correctly when a first-party API key is configured or no Haiku model is set
- Fixed scrolling in attached background sessions on Windows — PgUp/PgDn, mouse wheel, and Ctrl+O transcript navigation now work
- Fixed a crash when closing the terminal while attached to a background session
- Fixed on Windows, pressing ← in `claude agents` leaving the list unresponsive to keyboard input
- Fixed ghost characters at the left edge when switching panes in Agent View on Windows Terminal with CJK content

- Fixed `/resume` picker not showing sessions forked from a background session
- Fixed opening a session from `claude agents` or running `claude logs <id>` hanging when the background service is unresponsive — now times out after 10s with a recovery hint
- Fixed background Bash tasks spawned by subagents staying "Running" in SDK task panels after the process exits
- Fixed completed or stopped background sessions briefly failing to wake being permanently marked as a startup crash
- Fixed markdown links in `claude agents` attached sessions rendering as plain text instead of clickable hyperlinks
- Fixed custom `spinnerVerbs` applying to the post-turn duration message — past-tense built-ins like "Worked for 5s" are restored there
- `claude agents` / `--bg` rejection messages now name the specific gate (non-TTY, env var, or setting) instead of a generic message
- `claude --bg --name <label>` now echoes the name in the post-spawn confirmation
- `claude agents`: renaming a background session with Ctrl+R now updates the attached session's banner immediately
- Background session worktree isolation guard now applies for non-git VCS users with `WorktreeCreate` hooks configured
- Plugin marketplace add/update now respects `CLAUDE_CODE_PLUGIN_PREFER_HTTPS`
- `/plugin` now returns to the Installed list after enabling, disabling, or uninstalling a plugin
- `/doctor` now shows an exec-form example when a command hook is missing the `command` field
- Skill-listing truncation is no longer shown as a startup notification — run `/doctor` for the full breakdown
- Improved recovery from rare pre-response stream stalls — now retries streaming once instead of falling back to a slower non-streaming request
- Improved SDK/headless MCP startup: pre-wait now overlaps startup instead of blocking before the first turn (up to 2s faster with slow MCP servers)
- The post-survey follow-up hint now appears after every non-dismiss survey response with context-aware copy, making it easier to share more detail via /feedback.

## 2.1.143

- Added plugin dependency enforcement: `claude plugin disable` now refuses when another enabled plugin depends on the target (with a copy-pasteable disable-chain hint), and `claude plugin enable` force-enables transitive dependencies
- Added projected context cost (per-turn and per-invocation token estimates) to the `/plugin` marketplace browse pane
- Added `worktree.bgIsolation: "none"` setting to let background sessions edit the working copy directly without `EnterWorktree`, for repos where worktrees are impractical
- PowerShell tool now passes `-ExecutionPolicy Bypass`. Opt out with `CLAUDE_CODE_POWERSHELL_RESPECT_EXECUTION_POLICY=1`
- Background sessions now preserve the model and effort level you set after waking from idle
- Shift+Tab in attached agent sessions now includes auto mode in the cycle
- Fixed a corrupt `.credentials.json` with a non-array `scopes` value hanging the CLI on startup or silently aborting OAuth token refresh

- `claude agents` now accepts `--add-dir`, `--settings`, `--mcp-config`, and `--plugin-dir` and applies them to the dashboard and to background sessions dispatched from it
- `claude agents` accepts `--permission-mode`, `--model`, `--effort`, and `--dangerously-skip-permissions` to set defaults for sessions dispatched from the view
- `claude --bg --dangerously-skip-permissions` now persists across retire→wake
- Fixed background sessions silently capturing IDE file references into the warm spare's input, which caused the reference to be prepended to the next prompt dispatched from `claude agents`
- Worktree cleanup no longer falls back to `rm -rf` when `git worktree remove` fails, preventing loss of gitignored or in-progress files
- Fixed background-job sessions on macOS getting "Operation not permitted" errors when reading files under `~/Documents`, `~/Desktop`, or `~/Downloads`, even with Full Disk Access granted.
- `/bg` now preserves `--mcp-config`, `--settings`, `--add-dir`, `--plugin-dir`, and `--strict-mcp-config`, so backgrounded sessions keep their MCP servers and settings across respawn.
- Background sessions launched from `claude agents` now honor `permissions.defaultMode` from settings.json (was previously overridden to auto mode)
- Fixed: on Windows, pressing ← in `claude agents` while a response was streaming could leave the agents list unresponsive to all input
- `/bg` and `←`-detach now preserve `--fallback-model`, so backgrounded workers degrade to the fallback model on overload instead of hard-failing.
- `/bg` and `←`-detach now preserve `--allow-dangerously-skip-permissions`, so the forked worker keeps bypass-permissions available in its Shift+Tab cycle.
- Fixed: background daemon spawn now falls back to the running binary when the `~/.local/bin/claude` launcher is missing or non-executable
- Fixed `claude agents --allow-dangerously-skip-permissions` defaulting dispatched sessions to bypass mode instead of making it available in the permission cycle

## 2.1.142

- The `/plugin` details pane and `claude plugin details` now show LSP servers a plugin provides
- `/web-setup` warns before replacing an existing GitHub App connection
- Fixed `MCP_TOOL_TIMEOUT` not raising the per-request fetch timeout for remote HTTP and SSE MCP servers, which capped tool calls at 60 seconds regardless of the configured value
- Fixed background sessions not recognizing pre-existing git worktrees, blocking Edit while EnterWorktree refused to create a duplicate
- Fixed background sessions disappearing and daemon reconnect failing after macOS sleep/wake — the daemon now detects clock jumps instead of treating them as elapsed idle time

- Fixed background agents crash-looping when the Claude-in-Chrome extension is connected without a shared tab
- Fixed clicking links in an attached `claude agents` session — the background worker's headless browser shim no longer applies while attached
- Fixed `claude agents` "v to open in editor" using the daemon's default editor instead of your shell's `$EDITOR`/`$VISUAL`
- Fixed `claude agents` deadlocking on Windows with network-drive working directories; Ctrl+C now works during startup

- Fixed plugin advisories not naming every `plugin.json` key that shadows a default folder
- Improved reactive compaction: the first summarize attempt now seeds from the original request's overflow size, avoiding a wasted near-full-context retry
- Improved hook configuration error: configuring a prompt- or agent-type hook for `SessionStart`/`Setup`/`SubagentStart` now shows a clear "use a command-type hook instead" error
- Removed stale `/model claude-sonnet-4-20250514` suggestion from Usage Policy refusal messages

## 2.1.141

- Auto mode permission dialog now explains when a `permissions.ask` rule caused the prompt
- Restored the "view diff in your IDE" option on file-edit permission prompts when an IDE is connected
- Background agents launched via `/bg` or `←←` now preserve the current permission mode instead of reverting to default
- `claude agents`: agents that finish work but leave a background shell running now move to Completed instead of staying under Working

- Fixed `claude daemon status` and `/doctor` on Windows throwing when the daemon pipe key file is locked or unreadable — now shows the underlying error instead of an opaque failure
- Fixed `claude agents` showing the agent-type list instead of the dashboard when launched through a wrapper that adds flags
- Fixed `claude agents` opening a crashed session firing redundant dispatches when the working directory was deleted
- Fixed background jobs on a custom `ANTHROPIC_BASE_URL` gateway not getting auto-named — the namer now uses the main model when no Haiku model is configured
- Fixed `/model` in one session silently changing the autocompact threshold in other concurrent sessions
- Fixed switching permission mode while a tool-permission prompt is open not auto-dismissing the prompt when the new setting permits the tool
- Fixed pressing Enter while a permission/dialog prompt is open also submitting text in the input box

- Empty idle background sessions left over from `←` are now automatically retired by the daemon after 5 minutes

## 2.1.140

- Improved Agent tool `subagent_type` matching to accept case- and separator-insensitive values (e.g. `"Code Reviewer"` resolves to `code-reviewer`)
- Updated agent color palette

- Added hook `args: string[]` field (exec form) that spawns the command directly without a shell, so path placeholders never need quoting
- Added hook `continueOnBlock` config option for `PostToolUse` — set to `true` to feed the hook's rejection reason back to Claude and continue the turn

- Remote Control, `/schedule`, claude.ai MCP connectors, and notification preferences are now disabled when `ANTHROPIC_API_KEY` / `apiKeyHelper` / `ANTHROPIC_AUTH_TOKEN` is set, even if a Claude.ai login also exists. Unset the API key to use these features
- Fixed a deadlock where expired credentials and the `forceRemoteSettingsRefresh` policy setting blocked `claude auth login`/`logout`/`status` with no way to recover
- Fixed `autoAllowBashIfSandboxed` not auto-approving commands with shell expansions like `$VAR` and `$(cmd)`

## 2.1.133

- Added `worktree.baseRef` setting (`fresh` | `head`) to choose whether `--worktree`, `EnterWorktree`, and agent-isolation worktrees branch from `origin/<default>` or local `HEAD`. **Note:** the default `fresh` changes `EnterWorktree`'s base back to `origin/<default>` (it has been local `HEAD` since 2.1.128) — set `worktree.baseRef: "head"` to keep unpushed commits in new worktrees
- Added `sandbox.bwrapPath` and `sandbox.socatPath` managed settings (Linux/WSL) to specify custom bubblewrap and socat binary locations
- Added `parentSettingsBehavior` admin-tier key (`'first-wins' | 'merge'`) to let admins opt SDK `managedSettings` (parent tier) into the policy merge

- Fixed Read/Write/Edit being denied on mapped network drives passed via `--add-dir` / SDK `additionalDirectories`
- Fixed Remote Control stop/interrupt from claude.ai not fully canceling the CLI session the same way local Esc does, causing queued messages to never advance after interrupting a stuck tool or prompt

- Fixed `--resume` failing with `no low surrogate in string` when a tool error truncation split an emoji; pre-corrupted sessions are sanitized on load
- Fixed `--permission-mode` flag being ignored when resuming a plan-mode session with `-p --continue`/`--resume`, and plan mode not being re-applied after `ExitPlanMode` within the same session
- Fixed fullscreen mode showing a blank screen after laptop sleep/wake or Ctrl+Z/`fg` until the next keystroke or stream output
- Fixed cursor landing mid-grapheme on Ctrl+E/A/K/U/arrow keys when an Indic conjunct or ZWJ emoji wraps across lines

- Fixed unauthorized claude.ai MCP connectors showing as "failed" instead of "needs auth", and headless `-p` mode retrying non-transient 4xx connection failures
- Improved visual consistency in slash command dialogs and `/login`, `/upgrade`, `/extra-usage` dialog spacing

- Ctrl+R history picker now defaults to searching all prompts across all projects, matching pre-2.1.124 behavior. Press Ctrl+S to narrow to the current project or session
- Third-party deployments (Bedrock, Vertex, Foundry, or `ANTHROPIC_BASE_URL` gateway) no longer see spinner tips pointing at first-party Anthropic surfaces
- `skillOverrides` setting now works: `off` hides from model and `/`, `user-invocable-only` hides from model only, `name-only` collapses description

- Updated `/model` picker: collapsed duplicate Opus 4.7 entries, and current Opus now shows as "Opus" instead of "Opus 4.7"
- Subprocesses (Bash, hooks, MCP, LSP) no longer inherit `OTEL_*` environment variables, so OTEL-instrumented apps run via the Bash tool no longer pick up the CLI's own OTLP endpoint
- MCP: `workspace` is now a reserved server name — existing servers with that name will be skipped with a warning
- Reconnecting MCP servers no longer flood the conversation with full tool-name lists on every reconnect — re-announced tools are summarized by server prefix
- SDK hosts now receive a persistent `localSettings` suggestion for Bash permission prompts, so "Always allow" writes to `.claude/settings.local.json`
- `EnterWorktree` now creates the new branch from local HEAD as documented, instead of `origin/<default-branch>` — unpushed commits are no longer dropped
- Auto mode: when the classifier can't evaluate an action, the error now includes a hint (retry, `/compact`, or run with `--debug`)
- Fixed focus mode briefly dimming the previous response when submitting a new prompt
- Fixed stray "4;0;" desktop notification on every `/exit` in Kitty and other terminals that interpret OSC 9 as a notification
- Fixed Remote Control showing an empty "Opening your options…" message on rate limit instead of actionable upsell options

- Fixed markdown link labels being lost on terminals without OSC 8 hyperlink support — links now render as `label (url)` instead of just the URL
- Fixed sessions on 1M-context models with a smaller autocompact window being falsely blocked with "Prompt is too long" before reaching the actual API limit
- Fixed parallel shell tool calls: a failing read-only command (grep, git diff, ls) no longer cancels sibling calls

- Fixed `/fast` on 3P providers fuzzy-matching to an unrelated skill instead of showing "not available"
- Fixed Bedrock default model resolving to `global.*` instead of the region-appropriate prefix

- Fixed terminal progress indicator (OSC 9;4) flickering off between tool calls — stays visible across the full turn
- Fixed `/rename` without args failing on resumed sessions whose last entry is a compact boundary
- Fixed stale "remote-control is active" status lines from prior sessions appearing after `--resume`/`--continue`

- Fixed `/plugin update` never detecting new versions of npm-sourced plugins
- Fixed sub-agent summaries firing repeatedly while a sub-agent's transcript is static, capping worst-case token cost on idle sub-agents

## 2.1.126

- The `/model` picker now lists models from your gateway's `/v1/models` endpoint when `ANTHROPIC_BASE_URL` points at an Anthropic-compatible gateway
- - Added `claude project purge [path]` to delete all Claude Code state for a project (transcripts, tasks, file history, config entry) — supports `--dry-run`, `-y/--yes`, `-i/--interactive`, and `--all`
- `--dangerously-skip-permissions` now bypasses prompts for writes to `.claude/`, `.git/`, `.vscode/`, shell config files, and other previously-protected paths (catastrophic removal commands still prompt as a safety net)
- `claude auth login` now accepts the OAuth code pasted into the terminal when the browser callback can't reach localhost (WSL2, SSH, containers)
- `claude_code.skill_activated` OpenTelemetry event now fires for user-typed slash commands and carries a new `invocation_trigger` attribute (`"user-slash"`, `"claude-proactive"`, or `"nested-skill"`)
- Auto mode: the spinner now turns red when a permission check stalls, instead of looking like the tool is running
- Host-managed deployments (`CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST`) no longer auto-disable analytics on Bedrock/Vertex/Foundry
- Windows: PowerShell 7 installed via the Microsoft Store, MSI without PATH, or `.NET global tool` is now detected
- Windows: when the PowerShell tool is enabled, Claude now treats PowerShell as the primary shell instead of defaulting to Bash
- Read tool: removed the per-file malware-assessment reminder that could cause spurious refusals and "this is not malware" commentary on legacy models
- **Security:** Fixed `allowManagedDomainsOnly` / `allowManagedReadPathsOnly` being ignored when a higher-priority managed-settings source lacked a `sandbox` block
- Fixed pasting an image larger than 2000px breaking the session — images are now downscaled on paste, and oversized images in history are automatically removed and the request retried
- Fixed showing the login screen for "OAuth not allowed for organization" errors — now shows guidance to contact your admin
- Fixed OAuth login failing with timeout on slow or proxied connections, in IPv6-only devcontainers, and when the browser callback can't reach localhost
- Fixed a rare race where a concurrent credential write could clear a valid OAuth refresh token

- `SendMessage` now auto-resumes stopped agents in the background instead of returning an error
- Renamed `/fork` to `/branch` (`/fork` still works as an alias)
- [VSCode] Improved plan preview tab titles to use the plan's heading instead of "Claude's Plan"
- [VSCode] When option+click doesn't trigger native selection on macOS, the footer now points to the `macOptionClickForcesSelection` setting

## 2.1.71

- Added `/loop` command to run a prompt or slash command on a recurring interval (e.g. `/loop 5m check the deploy`)
- Added cron scheduling tools for recurring prompts within a session
- Added `voice:pushToTalk` keybinding to make the voice activation key rebindable in `keybindings.json` (default: space) — modifier+letter combos like `meta+k` have zero typing interference

- Fixed prompting for `cd <cwd> && git ...` on Windows when the model uses a mingw-style path
- Improved startup time by deferring native image processor loading to first use
- Improved bridge session reconnection to complete within seconds after laptop wake from sleep, instead of waiting up to 10 minutes
- Improved `/plugin uninstall` to disable project-scoped plugins in `.claude/settings.local.json` instead of modifying `.claude/settings.json`, so changes don't affect teammates
- Improved plugin-provided MCP server deduplication — servers that duplicate a manually-configured server (same command/URL) are now skipped, preventing duplicate connections and tool sets. Suppressions are shown in the `/plugin` menu.
- Updated `/debug` to toggle debug logging on mid-session, since debug logs are no longer written by default
- Removed startup notification noise for unauthenticated org-registered claude.ai connectors

## 2.1.70

- Fixed API 400 errors when using `ANTHROPIC_BASE_URL` with a third-party gateway — tool search now correctly detects proxy endpoints and disables `tool_reference` blocks
- Fixed `API Error: 400 This model does not support the effort parameter` when using custom Bedrock inference profiles or other model identifiers not matching standard Claude naming patterns
- Fixed empty model responses immediately after `ToolSearch` — the server renders tool schemas with system-prompt-style tags at the prompt tail, which could confuse models into stopping early
- Fixed prompt-cache bust when an MCP server with `instructions` connects after the first turn

- Fixed feature flags read during early startup never refreshing their disk cache, causing stale values to persist across sessions
- Fixed `permissions.defaultMode` settings values other than `acceptEdits` or `plan` being applied in Claude Code Remote environments — they are now ignored
- Fixed skill listing being re-injected on every `--resume` (~600 tokens saved per resume)
- Fixed teleport marker not rendering in VS Code teleported sessions
- Improved error message when microphone captures silence to distinguish from "no speech detected"
- Improved compaction to preserve images in the summarizer request, allowing prompt cache reuse for faster and cheaper compaction

- Reduced prompt input re-renders during turns by ~74%
- Reduced startup memory by ~426KB for users without custom CA certificates
- Reduced Remote Control `/poll` rate to once per 10 minutes while connected (was 1–2s), cutting server load ~300×. Reconnection is unaffected — transport loss immediately wakes fast polling.

- Fixed `--model claude-opus-4-0` and `--model claude-opus-4-1` resolving to deprecated Opus versions instead of current
- Fixed macOS keychain corruption when using multiple OAuth MCP servers. Large OAuth metadata blobs could overflow the `security -i` stdin buffer, silently leaving stale credentials behind and causing repeated `/login` prompts.

- Fixed a bug where bold and colored text in markdown output could shift to the wrong characters on Windows due to `\r\n` line endings.
- Fixed compaction failing when conversation contains many PDF documents by stripping document blocks alongside images before sending to the compaction API (anthropics/claude-code#26188)
