Claude Code 2.1.223

Aug 6, 20262.1.223Update soonOfficial source ↗

- Added owner wildcard entries (`"owner/*"`) to the `strictKnownMarketplaces` and `blockedMarketplaces` managed settings for allowing or blocking all marketplace repos under a GitHub org - Added a warning when workflow agents, forked skills, slash commands, or resumed background agents' requested subagent model is restricted and the parent model runs instead - Added a `/teleport` hint in cloud sessions showing how to continue locally with `claude --teleport <session id>` - Fixed a Bash permission bypass where a crafted command could hide parts of itself from permission checks - Fixed permission prompts so commands padded with tabs or invisible Unicode can no longer hide part of the command from the approval dialog - Fixed workflow scripts being able to use dynamic `import()` to run code outside the workflow sandbox - Fixed a permission gap where an agent definition's `bypassPermissions` mode ignored the org bypass-permissions disable policy - Fixed resuming a session after a mid-session `/cd` coming back empty - Fixed gateway model discovery hiding Claude models registered under provider-prefixed IDs such as `vertex_ai/claude-*` or `bedrock/anthropic.claude-*` - Fixed `modelOverrides` keys that aren't Anthropic model IDs being treated as the session's canonical model ID; unknown keys are now ignored as documented - Fixed managed settings: server-delivered settings no longer disable the env block of a machine-local `managed-settings.json` or MDM profile; admin env now merges per key - Fixed sandboxed commands failing to start on Linux when `sandbox.filesystem.denyWrite` covers the working directory - Fixed forked background agents getting stuck "already resuming" for the rest of the session when rebuilding the fork's parent prompt failed during resume - Fixed a resumed session failing every turn, or leaving the interactive app on an unresponsive error screen, when its history held a malformed diagnostics attachment - Fixed a rare hang when parsing unusual `git push` output - Changed `CLAUDE_CODE_DISABLE_1M_CONTEXT` to hold every Claude model with a native 1M window to 200K via auto-compaction, not just a fixed list; a startup warning now appears when auto-compaction isn't holding the session to 200K - Changed auto-compact to keep sessions on unrecognized model IDs within the assumed context window instead of letting them grow past it; set `CLAUDE_CODE_DISABLE_UNKNOWN_MODEL_WINDOW_ENFORCEMENT=1` to restore the previous behavior - Changed `/review` to be an alias of `/code-review`, which reviews the current diff or a PR (`/code-review <level> <pr#>`); use `/code-review ultra` for a deep cloud review - Changed `/code-review` with no effort level to reuse the level you typed last; type a level like `/code-review high` to change it

Claude Code 2.1.222

Aug 5, 20262.1.222RecommendedOfficial source ↗

- Fixed worktree-isolated sessions and their subagents being able to run destructive git commands against the main checkout; isolation now applies to file edits and Bash in every session type - Fixed PreToolUse auto-allow hooks bypassing tool restrictions in background agent tasks (summaries, compaction, renames) - Fixed `/usage-credits` on Team and Enterprise showing "you've already sent a usage credit request" for members whose earlier request was dismissed, blocking them from sending a new one - Fixed the startup connectivity check hanging and then failing behind an HTTPS proxy; it now uses the same proxy-aware transport as API requests and times out with a clear message - Fixed "Connection closed mid-response" errors being reported on responses that had actually completed - Fixed `/usage` overattributing usage to MCP servers: a server's share now reflects only the requests that actually consumed its tool results, instead of every turn after any call to it - Fixed sessions not linking to pull requests created after the branch was pushed, including through the GitHub REST API - Fixed org-restricted `model: opus`-style subagent and teammate family aliases dropping to the parent model instead of stepping down to the newest org-allowed model in the family - Fixed stream idle timeout firing on custom `ANTHROPIC_BASE_URL` gateways despite server keep-alive pings arriving on the wire - Fixed claude.ai connectors being falsely marked as needing authorization when the session token is invalid — they now show a `/login` hint instead - Fixed tool errors not being displayed for tools no longer available locally, for example after an MCP server is removed - Fixed `SendMessage` rejecting a long summary — it now truncates instead, so sends no longer fail on a character limit - Fixed the spinner's effort label in a subagent's transcript view showing the session's effort level instead of the subagent's own `effort:` setting - Fixed rare crashes when a file watcher hit a filesystem error or during file-watcher teardown - Fixed screen readers re-reading the whole input line on every backspace in `--ax-screen-reader` mode — end-of-line deletions now echo just the deleted characters - Fixed host model-selection keys not taking precedence over a stale on-disk `managed-settings.json` when `CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST` is set - Improved auto mode safety: messages sent to other agent sessions via `SendMessage` are now evaluated by the permission classifier before dispatch - Improved the refusal when Claude tries to invoke a skill with `disable-model-invocation`: Claude is now told to ask you to run the skill instead of replicating its workflow - Improved the `/diff` view, the Remote Control workspace diff, and file-edit diffs in Claude Code on the web sessions to use raw git blob content, ignoring workspace-configured diff drivers and textconv - Changed Remote Control auto-start so repo-local settings (`.claude/settings.json` or `.claude/settings.local.json`) can no longer turn it on (they can still turn it off); enable it at user scope via `/config` - Removed ultraplan feature

Claude Code 2.1.221

Aug 4, 20262.1.221RecommendedOfficial source ↗

- [VSCode] Added Focus view: a chat-menu toggle that hides tool activity behind an expandable per-turn summary with a live running-tool indicator, toggled with `Ctrl+Alt+F` or the "Claude Code: Toggle Focus view" command - Added `mode: "mask"` for sandbox credential files on Linux and WSL — sandboxed commands read a sentinel copy (the whole file, or just the spans captured by an `extract` regex) while the sandbox proxy substitutes the real value on egress; on macOS file masking falls back to `deny` - Added warnings to `claude plugin validate` when a marketplace or plugin name would be rejected by Claude Desktop's managed marketplace sync - Added a `prompt-audit` subcommand to the `claude-api` skill for auditing prompts and tool descriptions for patterns written for older models - Fixed a Bash tool permission-check bypass where zsh could execute hidden commands in `[[ ]]` regex conditionals; affected commands now prompt for permission - Fixed PowerShell permission checks mishandling paths containing quote characters on Windows; such paths now prompt for approval - Fixed the thinking toggle having no effect for the rest of a session that started with thinking off; disabling an MCP server mid-connect no longer silently reverts - Fixed MCP servers from `--mcp-config` not being connected before the first turn in print mode (`-p`), which made the model emit tool calls as literal text - Fixed @-mentioned files being silently dropped when pressing Esc to retract a prompt and resubmitting it - Fixed a crash when preparing API requests for SDK MCP tools named after built-in object properties such as `constructor` - Fixed WebSearch failing with a 400 error at effort `xhigh`/`max` when thinking is disabled - Fixed sandboxed large uploads failing with TLS errors through the sandbox proxy - Fixed Team and Enterprise spend-limit message incorrectly blaming the org's monthly limit instead of your individual spend limit - Fixed Bedrock authentication with AWS SSO named profiles failing in desktop-managed sessions on Windows machines that set a stray `HOME` environment variable - Fixed `CLAUDE_CODE_RESUME_INTERRUPTED_TURN=0` not disabling interrupted-turn auto-resume; falsy values are now honored - Fixed a rare wake-from-sleep race where two Claude Code processes could both refresh the same MCP connector or WIF OAuth token at once, forcing re-authentication - Fixed renaming a session from Claude Code Desktop or claude.ai not updating the CLI's session name; session names from every rename surface are now sanitized - Fixed plugin- and org-delivered skills named after terminal-only built-ins (e.g. `/help`, `/feedback`) being un-invocable in non-interactive sessions - Fixed the "Plugins changed" notification lingering after plugins were reloaded instead of clearing - Fixed Vim mode: the yank register now survives dialogs, history search, and the transcript view instead of being silently emptied - Fixed Vim mode: undoing back to an empty prompt now arms the "press ← again" confirm before returning to the agent view - Improved tool search on Google Vertex AI: re-enabled for Claude 4.5-generation and newer models - Improved auto mode: permission checks for parallel tool calls are now cache-efficient, and switching modes while a check is pending reliably prompts instead of applying the stale result - Reduced prompt-cache costs for auto-mode permission checks by reusing the cached conversation prefix across decisions - Improved Stats panel to count cache tokens in its token totals, with a breakdown by input, output, cache read, and cache write - Improved `/ultrareview` error messages when a repo shares no history with its base: a checkout with no branches is now refused up front with advice to create one, and refusal hints no longer suggest `git fetch --unshallow` on clones that are already complete - Improved Windows startup: process creation times are now read via a native kernel32 call instead of spawning PowerShell, so endpoint security tools that gate `powershell.exe` no longer prompt - Changed background sessions to commit and push to preserve work, open a draft PR only when the task calls for one, follow your CLAUDE.md git instructions, and always end by reporting where the work lives - Changed `/plugin install` to refresh a stale marketplace catalog and retry before reporting a plugin not found - Changed plugins installed from `/plugin` to activate immediately when safe, instead of always requiring `/reload-plugins` - Changed plugins to accept `"."` as a `skills` path, and the root-level `SKILL.md` validation error now suggests using the plugin root - Changed `/status` to show the session kind: `interactive`, or a background job that is `attached` or `unattended` - Changed emoji autocomplete to accept common alternate shortcodes like `:thumbsup:`, `:thumbsdown:`, and `:love:` - Changed sessions forked with `/fork` to create a new worktree of their own instead of working in the original session's checkout - Changed Claude in Chrome to close the browser tabs it opens once it no longer needs them - Changed fast mode to report on the stream when usage credits run out mid-session, instead of failing silently - Changed Monitor: a watch that exits without producing any output now says so instead of reporting "stream ended" - Changed the Gateway `model` field validation: non-string values are rejected with a 400 instead of being forwarded - Removed the repeated "Permission mode changed while the auto-mode classifier call was queued" notice from approval prompts

Claude Code 2.1.219

Jul 25, 20262.1.219RecommendedOfficial source ↗

- 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

Claude Code 2.1.218

Jul 23, 20262.1.218Update soonOfficial source ↗

- 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

Claude Code 2.1.217

Jul 22, 20262.1.217Update soonOfficial source ↗

- 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

Claude Code 2.1.216

Jul 21, 20262.1.216Update soonOfficial source ↗

- 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

Claude Code 2.1.214

Jul 18, 20262.1.214Update soonOfficial source ↗

- 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"`

Claude Code 2.1.212

Jul 17, 20262.1.212RecommendedOfficial 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 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
