Release Notes

anthropics/claude-code (npm:@​anthropic-ai/claude-code)

v2.1.212

Compare Source

• /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 " 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

v2.1.211

Compare Source

• 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.

v2.1.210

Compare Source

• 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

v2.1.209

Compare Source

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

v2.1.208

Compare Source

• 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
• 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)

v2.1.207

Compare Source

• 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
