3## 2.1.94
4
5- Added support for Amazon Bedrock powered by Mantle, set `CLAUDE_CODE_USE_MANTLE=1`
6- Changed default effort level from medium to high for API-key, Bedrock/Vertex/Foundry, Team, and Enterprise users (control this with `/effort`)
7- Added compact `Slacked #channel` header with a clickable channel link for Slack MCP send-message tool calls
8- Added `keep-coding-instructions` frontmatter field support for plugin output styles
9- Added `hookSpecificOutput.sessionTitle` to `UserPromptSubmit` hooks for setting the session title
10- Plugin skills declared via `"skills": ["./"]` now use the skill's frontmatter `name` for the invocation name instead of the directory basename, giving a stable name across install methods
11- Fixed agents appearing stuck after a 429 rate-limit response with a long Retry-After header — the error now surfaces immediately instead of silently waiting
12- Fixed Console login on macOS silently failing with "Not logged in" when the login keychain is locked or its password is out of sync — the error is now surfaced and `claude doctor` diagnoses the fix
13- Fixed plugin skill hooks defined in YAML frontmatter being silently ignored
14- Fixed plugin hooks failing with "No such file or directory" when `CLAUDE_PLUGIN_ROOT` was not set
15- Fixed `${CLAUDE_PLUGIN_ROOT}` resolving to the marketplace source directory instead of the installed cache for local-marketplace plugins on startup
16- Fixed scrollback showing the same diff repeated and blank pages in long-running sessions
17- Fixed multiline user prompts in the transcript indenting wrapped lines under the `❯` caret instead of under the text
18- Fixed Shift+Space inserting the literal word "space" instead of a space character in search inputs
19- Fixed hyperlinks opening two browser tabs when clicked inside tmux running in an xterm.js-based terminal (VS Code, Hyper, Tabby)
20- Fixed an alt-screen rendering bug where content height changes mid-scroll could leave compounding ghost lines
21- Fixed `FORCE_HYPERLINK` environment variable being ignored when set via `settings.json` `env`
22- Fixed native terminal cursor not tracking the selected tab in dialogs, so screen readers and magnifiers can follow tab navigation
23- Fixed Bedrock invocation of Sonnet 3.5 v2 by using the `us.` inference profile ID
24- Fixed SDK/print mode not preserving the partial assistant response in conversation history when interrupted mid-stream
25- Improved `--resume` to resume sessions from other worktrees of the same repo directly instead of printing a `cd` command
26- Fixed CJK and other multibyte text being corrupted with U+FFFD in stream-json input/output when chunk boundaries split a UTF-8 sequence
27- [VSCode] Reduced cold-open subprocess work on starting a session
28- [VSCode] Fixed dropdown menus selecting the wrong item when the mouse was over the list while typing or using arrow keys
29- [VSCode] Added a warning banner when `settings.json` files fail to parse, so users know their permission rules are not being applied
30
31## 2.1.92
32
33- Added `forceRemoteSettingsRefresh` policy setting: when set, the CLI blocks startup until remote managed settings are freshly fetched, and exits if the fetch fails (fail-closed)
34- Added interactive Bedrock setup wizard accessible from the login screen when selecting "3rd-party platform" — guides you through AWS authentication, region configuration, credential verification, and model pinning
35- Added per-model and cache-hit breakdown to `/cost` for subscription users
36- `/release-notes` is now an interactive version picker
37- Remote Control session names now use your hostname as the default prefix (e.g. `myhost-graceful-unicorn`), overridable with `--remote-control-session-name-prefix`
38- Pro users now see a footer hint when returning to a session after the prompt cache has expired, showing roughly how many tokens the next turn will send uncached
39- Fixed subagent spawning permanently failing with "Could not determine pane count" after tmux windows are killed or renumbered during a long-running session
40- Fixed prompt-type Stop hooks incorrectly failing when the small fast model returns `ok:false`, and restored `preventContinuation:true` semantics for non-Stop prompt-type hooks
41- Fixed tool input validation failures when streaming emits array/object fields as JSON-encoded strings
42- Fixed an API 400 error that could occur when extended thinking produced a whitespace-only text block alongside real content
43- Fixed accidental feedback survey submissions from auto-pilot keypresses and consecutive-prompt digit collisions
44- Fixed misleading "esc to interrupt" hint appearing alongside "esc to clear" when a text selection exists in fullscreen mode during processing
45- Fixed Homebrew install update prompts to use the cask's release channel (`claude-code` → stable, `claude-code@latest` → latest)
46- Fixed `ctrl+e` jumping to the end of the next line when already at end of line in multiline prompts
47- Fixed an issue where the same message could appear at two positions when scrolling up in fullscreen mode (iTerm2, Ghostty, and other terminals with DEC 2026 support)
48- Fixed idle-return "/clear to save X tokens" hint showing cumulative session tokens instead of current context size
49- Fixed plugin MCP servers stuck "connecting" on session start when they duplicate a claude.ai connector that is unauthenticated
50- Improved Write tool diff computation speed for large files (60% faster on files with tabs/`&`/`$`)
51- Removed `/tag` command
52- Removed `/vim` command (toggle vim mode via `/config` → Editor mode)
53- Linux sandbox now ships the `apply-seccomp` helper in both npm and native builds, restoring unix-socket blocking for sandboxed commands
54
55## 2.1.91
56
57- Added MCP tool result persistence override via `_meta["anthropic/maxResultSizeChars"]` annotation (up to 500K), allowing larger results like DB schemas to pass through without truncation
58- Added `disableSkillShellExecution` setting to disable inline shell execution in skills, custom slash commands, and plugin commands
59- Added support for multi-line prompts in `claude-cli://open?q=` deep links (encoded newlines `%0A` no longer rejected)
60- Plugins can now ship executables under `bin/` and invoke them as bare commands from the Bash tool
61- Fixed transcript chain breaks on `--resume` that could lose conversation history when async transcript writes fail silently
62- Fixed `cmd+delete` not deleting to start of line on iTerm2, kitty, WezTerm, Ghostty, and Windows Terminal
63- Fixed plan mode in remote sessions losing track of the plan file after a container restart, which caused permission prompts on plan edits and an empty plan-approval modal
64- Fixed JSON schema validation for `permissions.defaultMode: "auto"` in settings.json
65- Fixed Windows version cleanup not protecting the active version's rollback copy
66- `/feedback` now explains why it's unavailable instead of disappearing from the slash menu
67- Improved `/claude-api` skill guidance for agent design patterns including tool surface decisions, context management, and caching strategy
68- Improved performance: faster `stripAnsi` on Bun by routing through `Bun.stripANSI`
69- Edit tool now uses shorter `old_string` anchors, reducing output tokens
70
71## 2.1.90
72
73- Added `/powerup` — interactive lessons teaching Claude Code features with animated demos
74- Added `CLAUDE_CODE_PLUGIN_KEEP_MARKETPLACE_ON_FAILURE` env var to keep the existing marketplace cache when `git pull` fails, useful in offline environments
75- Added `.husky` to protected directories (acceptEdits mode)
76- Fixed an infinite loop where the rate-limit options dialog would repeatedly auto-open after hitting your usage limit, eventually crashing the session
77- Fixed `--resume` causing a full prompt-cache miss on the first request for users with deferred tools, MCP servers, or custom agents (regression since v2.1.69)
78- Fixed `Edit`/`Write` failing with "File content has changed" when a PostToolUse format-on-save hook rewrites the file between consecutive edits
79- Fixed `PreToolUse` hooks that emit JSON to stdout and exit with code 2 not correctly blocking the tool call
80- Fixed collapsed search/read summary badge appearing multiple times in fullscreen scrollback when a CLAUDE.md file auto-loads during a tool call
81- Fixed auto mode not respecting explicit user boundaries ("don't push", "wait for X before Y") even when the action would otherwise be allowed
82- Fixed click-to-expand hover text being nearly invisible on light terminal themes
83- Fixed UI crash when malformed tool input reached the permission dialog
84- Fixed headers disappearing when scrolling `/model`, `/config`, and other selection screens
85- Hardened PowerShell tool permission checks: fixed trailing `&` background job bypass, `-ErrorAction Break` debugger hang, archive-extraction TOCTOU, and parse-fail fallback deny-rule degradation
86- Improved performance: eliminated per-turn JSON.stringify of MCP tool schemas on cache-key lookup
87- Improved performance: SSE transport now handles large streamed frames in linear time (was quadratic)
88- Improved performance: SDK sessions with long conversations no longer slow down quadratically on transcript writes
89- Improved `/resume` all-projects view to load project sessions in parallel, improving load times for users with many projects
90- Changed `--resume` picker to no longer show sessions created by `claude -p` or SDK invocations
91- Removed `Get-DnsClientCache` and `ipconfig /displaydns` from auto-allow (DNS cache privacy)
92
93## 2.1.89
94
95- Added `"defer"` permission decision to `PreToolUse` hooks — headless sessions can pause at a tool call and resume with `-p --resume` to have the hook re-evaluate
96- Added `CLAUDE_CODE_NO_FLICKER=1` environment variable to opt into flicker-free alt-screen rendering with virtualized scrollback
97- Added `PermissionDenied` hook that fires after auto mode classifier denials — return `{retry: true}` to tell the model it can retry
98- Added named subagents to `@` mention typeahead suggestions
99- Added `MCP_CONNECTION_NONBLOCKING=true` for `-p` mode to skip the MCP connection wait entirely, and bounded `--mcp-config` server connections at 5s instead of blocking on the slowest server
100- Auto mode: denied commands now show a notification and appear in `/permissions` → Recent tab where you can retry with `r`
101- Fixed `Edit(//path/**)` and `Read(//path/**)` allow rules to check the resolved symlink target, not just the requested path
102- Fixed voice push-to-talk not activating for some modifier-combo bindings, and voice mode on Windows failing with "WebSocket upgrade rejected with HTTP 101"
103- Fixed Edit/Write tools doubling CRLF on Windows and stripping Markdown hard line breaks (two trailing spaces)
104- Fixed `StructuredOutput` schema cache bug causing ~50% failure rate when using multiple schemas
105- Fixed memory leak where large JSON inputs were retained as LRU cache keys in long-running sessions
106- Fixed a crash when removing a message from very large session files (over 50MB)
107- Fixed LSP server zombie state after crash — server now restarts on next request instead of failing until session restart
108- Fixed prompt history entries containing CJK or emoji being silently dropped when they fall on a 4KB boundary in `~/.claude/history.jsonl`
109- Fixed `/stats` undercounting tokens by excluding subagent usage, and losing historical data beyond 30 days when the stats cache format changes
110- Fixed `-p --resume` hangs when the deferred tool input exceeds 64KB or no deferred marker exists, and `-p --continue` not resuming deferred tools
111- Fixed `claude-cli://` deep links not opening on macOS
112- Fixed MCP tool errors truncating to only the first content block when the server returns multi-element error content
113- Fixed skill reminders and other system context being dropped when sending messages with images via the SDK
114- Fixed PreToolUse/PostToolUse hooks to receive `file_path` as an absolute path for Write/Edit/Read tools, matching the documented behavior
115- Fixed autocompact thrash loop — now detects when context refills to the limit immediately after compacting three times in a row and stops with an actionable error instead of burning API calls
116- Fixed prompt cache misses in long sessions caused by tool schema bytes changing mid-session
117- Fixed nested CLAUDE.md files being re-injected dozens of times in long sessions that read many files
118- Fixed `--resume` crash when transcript contains a tool result from an older CLI version or interrupted write
119- Fixed misleading "Rate limit reached" message when the API returned an entitlement error — now shows the actual error with actionable hints
120- Fixed hooks `if` condition filtering not matching compound commands (`ls && git push`) or commands with env-var prefixes (`FOO=bar git push`)
121- Fixed collapsed search/read group badges duplicating in terminal scrollback during heavy parallel tool use
122- Fixed notification `invalidates` not clearing the currently-displayed notification immediately
123- Fixed prompt briefly disappearing after submit when background messages arrived during processing
124- Fixed Devanagari and other combining-mark text being truncated in assistant output
125- Fixed rendering artifacts on main-screen terminals after layout shifts
126- Fixed voice mode failing to request microphone permission on macOS Apple Silicon

130- Fixed a potential out-of-memory crash when the Edit tool was used on very large files (>1 GiB)
131- Improved collapsed tool summary to show "Listed N directories" for `ls`/`tree`/`du` instead of "Read N files"
132- Improved Bash tool to warn when a formatter/linter command modifies files you have previously read, preventing stale-edit errors
133- Improved `@`-mention typeahead to rank source files above MCP resources with similar names
134- Improved PowerShell tool prompt with version-appropriate syntax guidance (5.1 vs 7+)
135- Changed `Edit` to work on files viewed via `Bash` with `sed -n` or `cat`, without requiring a separate `Read` call first
136- Changed hook output over 50K characters to be saved to disk with a file path + preview instead of being injected directly into context
137- Changed `cleanupPeriodDays: 0` in settings.json to be rejected with a validation error — it previously silently disabled transcript persistence
138- Changed thinking summaries to no longer be generated by default in interactive sessions — set `showThinkingSummaries: true` in settings.json to restore
139- Documented `TaskCreated` hook event and its blocking behavior
140- Preserved task notifications when backgrounding a running command with Ctrl+B
141- PowerShell tool on Windows: external-command arguments containing both a double-quote and whitespace now prompt instead of auto-allowing (PS 5.1 argument-splitting hardening)
142- `/env` now applies to PowerShell tool commands (previously only affected Bash)
143- `/usage` now hides redundant "Current week (Sonnet only)" bar for Pro and Enterprise plans
144- Image paste no longer inserts a trailing space
145- Pasting `!command` into an empty prompt now enters bash mode, matching typed `!` behavior
146- `/buddy` is here for April 1st — hatch a small creature that watches you code

150- Fixed messages in Cowork Dispatch not getting delivered
151
152## 2.1.86
153
154- Added `X-Claude-Code-Session-Id` header to API requests so proxies can aggregate requests by session without parsing the body
155- Added `.jj` and `.sl` to VCS directory exclusion lists so Grep and file autocomplete don't descend into Jujutsu or Sapling metadata
156- Fixed `--resume` failing with "tool_use ids were found without tool_result blocks" on sessions created before v2.1.85
157- Fixed Write/Edit/Read failing on files outside the project root (e.g., `~/.claude/CLAUDE.md`) when conditional skills or rules are configured

167- Fixed a regression where pressing Enter after clicking could leave the transcript blank until the response arrived
168- Fixed `ultrathink` hint lingering after deleting the keyword
169- Fixed memory growth in long sessions from markdown/highlight render caches retaining full content strings
170- Reduced startup event-loop stalls when many claude.ai MCP connectors are configured (macOS keychain cache extended from 5s to 30s)
171- Reduced token overhead when mentioning files with `@` — raw string content no longer JSON-escaped
172- Improved prompt cache hit rate for Bedrock, Vertex, and Foundry users by removing dynamic content from tool descriptions
173- Memory filenames in the "Saved N memories" notice now highlight on hover and open on click
174- Skill descriptions in the `/skills` listing are now capped at 250 characters to reduce context usage
175- Changed `/skills` menu to sort alphabetically for easier scanning
176- Auto mode now shows "unavailable for your plan" when disabled by plan restrictions (was "temporarily unavailable")
177- [VSCode] Fixed extension incorrectly showing "Not responding" during long-running operations
178- [VSCode] Fixed extension defaulting Max plan users to Sonnet after the OAuth token refreshes (8 hours after login)

180
181## 2.1.85
182
183- Added `CLAUDE_CODE_MCP_SERVER_NAME` and `CLAUDE_CODE_MCP_SERVER_URL` environment variables to MCP `headersHelper` scripts, allowing one helper to serve multiple servers
184- Added conditional `if` field for hooks using permission rule syntax (e.g., `Bash(git *)`) to filter when they run, reducing process spawning overhead
185- Added timestamp markers in transcripts when scheduled tasks (`/loop`, `CronCreate`) fire
186- Added trailing space after `[Image #N]` placeholder when pasting images
187- Deep link queries (`claude-cli://open?q=…`) now support up to 5,000 characters, with a "scroll to review" warning for long pre-filled prompts
188- MCP OAuth now follows RFC 9728 Protected Resource Metadata discovery to find the authorization server
189- Plugins blocked by organization policy (`managed-settings.json`) can no longer be installed or enabled, and are hidden from marketplace views
190- PreToolUse hooks can now satisfy `AskUserQuestion` by returning `updatedInput` alongside `permissionDecision: "allow"`, enabling headless integrations that collect answers via their own UI
191- `tool_parameters` in OpenTelemetry tool_result events are now gated behind `OTEL_LOG_TOOL_DETAILS=1`
192- Fixed `/compact` failing with "context exceeded" when the conversation has grown too large for the compact request itself to fit

200- Fixed memory leak in remote sessions when a streaming response is interrupted
201- Fixed persistent ECONNRESET errors during edge connection churn by using a fresh TCP connection on retry
202- Fixed prompts getting stuck in the queue after running certain slash commands, with up-arrow unable to retrieve them

217- Added `ANTHROPIC_DEFAULT_{OPUS,SONNET,HAIKU}_MODEL_SUPPORTS` env vars to override effort/thinking capability detection for pinned default models for 3p (Bedrock, Vertex, Foundry), and `_MODEL_NAME`/`_DESCRIPTION` to customize the `/model` picker label
218- Added `CLAUDE_STREAM_IDLE_TIMEOUT_MS` env var to configure the streaming idle watchdog threshold (default 90s)
219- Added `TaskCreated` hook that fires when a task is created via `TaskCreate`

225- Rules and skills `paths:` frontmatter now accepts a YAML list of globs
226- MCP tool descriptions and server instructions are now capped at 2KB to prevent OpenAPI-generated servers from bloating context
227- MCP servers configured both locally and via claude.ai connectors are now deduplicated — the local config wins
228- Background bash tasks that appear stuck on an interactive prompt now surface a notification after ~45 seconds
229- Token counts ≥1M now display as "1.5m" instead of "1512.6k"
230- Global system-prompt caching now works when `ToolSearch` is enabled, including for users with MCP tools configured
231- Fixed voice push-to-talk: holding the voice key no longer leaks characters into the text input, and transcripts now insert at the correct position
232- Fixed up/down arrow keys being unresponsive when a footer item is focused
233- Fixed `Ctrl+U` (kill-to-line-start) being a no-op at line boundaries in multiline input, so repeated `Ctrl+U` now clears across lines

240- Fixed MCP tool/resource cache leak on server reconnect
241- Fixed a startup performance issue where partial clone repositories (Scalar/GVFS) triggered mass blob downloads

243- Fixed spurious "Not logged in" errors on macOS caused by transient keychain read failures
244- Fixed cold-start race where core tools could be deferred without their bypass active, causing Edit/Write to fail with InputValidationError on typed parameters
245- Improved detection for dangerous removals of Windows drive roots (`C:\`, `C:\Windows`, etc.)
246- Improved interactive startup by ~30ms by running `setup()` in parallel with slash command and agent loading
247- Improved startup for `claude "prompt"` with MCP servers — the REPL now renders immediately instead of blocking until all servers connect
248- Improved Remote Control to show a specific reason when blocked instead of a generic "not yet enabled" message
249- Improved p90 prompt cache rate
250- Reduced scroll-to-top resets in long sessions by making the message window immune to compaction and grouping changes
251- Reduced terminal flickering when animated tool progress scrolls above the viewport
252- Changed issue/PR references to only become clickable links when written as `owner/repo#123` — bare `#123` is no longer auto-linked
253- Slash commands unavailable for the current auth setup (`/voice`, `/mobile`, `/chrome`, `/upgrade`, etc.) are now hidden instead of shown
254- [VSCode] Added rate limit warning banner with usage percentage and reset time
255- Stats screenshot (Ctrl+S in /stats) now works in all builds and is 16× faster
256
257## 2.1.83
258
259- Added `managed-settings.d/` drop-in directory alongside `managed-settings.json`, letting separate teams deploy independent policy fragments that merge alphabetically
260- Added `CwdChanged` and `FileChanged` hook events for reactive environment management (e.g., direnv)
261- Added `sandbox.failIfUnavailable` setting to exit with an error when sandbox is enabled but cannot start, instead of running unsandboxed
262- Added `disableDeepLinkRegistration` setting to prevent `claude-cli://` protocol handler registration
263- Added `CLAUDE_CODE_SUBPROCESS_ENV_SCRUB=1` to strip Anthropic and cloud provider credentials from subprocess environments (Bash tool, hooks, MCP stdio servers)
264- Added transcript search — press `/` in transcript mode (`Ctrl+O`) to search, `n`/`N` to step through matches
265- Added `Ctrl+X Ctrl+E` as an alias for opening the external editor (readline-native binding; `Ctrl+G` still works)
266- Pasted images now insert an `[Image #N]` chip at the cursor so you can reference them positionally in your prompt
267- Agents can now declare `initialPrompt` in frontmatter to auto-submit a first turn
268- `chat:killAgents` and `chat:fastMode` are now rebindable via `~/.claude/keybindings.json`

270- Fixed Claude Code hanging on exit on macOS
271- Fixed screen flashing blank after being idle for a few seconds
272- Fixed a hang when diffing very large files with few common lines — diffs now time out after 5 seconds and fall back gracefully

274- Fixed a startup regression where Claude Code would wait ~3s for claude.ai MCP config fetch before proceeding
275- Fixed `--mcp-config` CLI flag bypassing `allowedMcpServers`/`deniedMcpServers` managed policy enforcement
276- Fixed claude.ai MCP connectors (Slack, Gmail, etc.) not being available in single-turn `--print` mode
277- Fixed `caffeinate` process not properly terminating when Claude Code exits, preventing Mac from sleeping
278- Fixed bash mode not activating when tab-accepting `!`-prefixed command suggestions
279- Fixed stale slash command selection showing wrong highlighted command after navigating suggestions
280- Fixed `/config` menu showing both the search cursor and list selection at the same time

283- Fixed `--channels` showing "Channels are not currently available" on first launch after upgrade
284- Fixed uninstalled plugin hooks continuing to fire until the next session
285- Fixed queued commands flickering during streaming responses
286- Fixed slash commands being sent to the model as text when submitted while a message is processing
287- Fixed scrollback jumping when collapsed read/search groups finish after scrolling offscreen
288- Fixed scrollback jumping to top when the model starts or stops thinking

291- Fixed ghost characters appearing in height-constrained lists when items overflow
292- Fixed `Ctrl+B` interfering with readline backward-char at an idle prompt — it now only fires when a foreground task can be backgrounded

307- Faster `claude -p` startup with unauthenticated HTTP/SSE MCP servers (~600ms saved)
308- Bash ghost-text suggestions now include just-submitted commands immediately
309- Increased non-streaming fallback token cap (21k → 64k) and timeout (120s → 300s local) so fallback requests are less likely to be truncated

601- Simplified effort levels to low/medium/high (removed max) with new symbols (○ ◐ ●) and a brief notification instead of a persistent icon. Use `/effort auto` to reset to default
602- Improved `/config` — Escape now cancels changes, Enter saves and closes, Space toggles settings
603- Improved up-arrow history to show current session's messages first when running multiple concurrent sessions
604- Improved voice input transcription accuracy for repo names and common dev terms (regex, OAuth, JSON)
605- Improved bash command parsing by switching to a native module — faster initialization and no memory leak
606- Reduced bundle size by ~510 KB
607- Changed CLAUDE.md HTML comments (`<!-- ... -->`) to be hidden from Claude when auto-injected. Comments remain visible when read with the Read tool
608- Fixed slow exits when background tasks or hooks were slow to respond
609- Fixed agent task progress stuck on "Initializing…"
610- Fixed skill hooks firing twice per event when a hooks-enabled skill is invoked by the model
611- Fixed several voice mode issues: occasional input lag, false "No speech detected" errors after releasing push-to-talk, and stale transcripts re-filling the prompt after submission
612- Fixed `--continue` not resuming from the most recent point after `--compact`
613- Fixed bash security parsing edge cases
614- Added support for marketplace git URLs without `.git` suffix (Azure DevOps, AWS CodeCommit)
615- Improved marketplace clone failure messages to show diagnostic info even when git produces no stderr
616- Fixed several plugin issues: installation failing on Windows with `EEXIST` error in OneDrive folders, marketplace blocking user-scope installs when a project-scope install exists, `CLAUDE_CODE_PLUGIN_CACHE_DIR` creating literal `~` directories, and `plugin.json` with marketplace-only fields failing to load
617- Fixed feedback survey appearing too frequently in long sessions
618- Fixed `--effort` CLI flag being reset by unrelated settings writes on startup
619- Fixed backgrounded Ctrl+B queries losing their transcript or corrupting the new conversation after `/clear`
620- Fixed `/clear` killing background agent/bash tasks — only foreground tasks are now cleared
621- Fixed worktree isolation issues: Task tool resume not restoring cwd, and background task notifications missing `worktreePath` and `worktreeBranch`
622- Fixed `/model` not displaying results when run while Claude is working
623- Fixed digit keys selecting menu options instead of typing in plan mode permission prompt's text input
624- Fixed sandbox permission issues: certain file write operations incorrectly allowed without prompting, and output redirections to allowlisted directories (like `/tmp/claude/`) prompting unnecessarily
625- Improved CPU utilization in long sessions
626- Fixed prompt cache invalidation in SDK `query()` calls, reducing input token costs up to 12x
627- Fixed Escape key becoming unresponsive after cancelling a query
628- Fixed double Ctrl+C not exiting when background agents or tasks are running
629- Fixed team agents to inherit the leader's model
630- Fixed "Always Allow" saving permission rules that never match again
631- Fixed several hooks issues: `transcript_path` pointing to the wrong directory for resumed/forked sessions, agent `prompt` being silently deleted from settings.json on every settings write, PostToolUse block reason displaying twice, async hooks not receiving stdin with bash `read -r`, and validation error message showing an example that fails validation
632- Fixed session crashes in Desktop/SDK when Read returned files containing U+2028/U+2029 characters
633- Fixed terminal title being cleared on exit even when `CLAUDE_CODE_DISABLE_TERMINAL_TITLE` was set
634- Fixed several permission rule matching issues: wildcard rules not matching commands with heredocs, embedded newlines, or no arguments; `sandbox.excludedCommands` failing with env var prefixes; "always allow" suggesting overly broad prefixes for nested CLI tools; and deny rules not applying to all command forms
635- Fixed oversized and truncated images from Bash data-URL output
636- Fixed a crash when resuming sessions that contained Bedrock API errors
637- Fixed intermittent "expected boolean, received string" validation errors on Edit, Bash, and Grep tool inputs
638- Fixed multi-line session titles when forking from a conversation whose first message contained newlines
639- Fixed queued messages not showing attached images, and images being lost when pressing ↑ to edit a queued message
640- Fixed parallel tool calls where a failed Read/WebFetch/Glob would cancel its siblings — only Bash errors now cascade
641- VSCode: Fixed scroll speed in integrated terminals not matching native terminals
642- VSCode: Fixed Shift+Enter submitting input instead of inserting a newline for users with older keybindings
643- VSCode: Added effort level indicator on the input border
644- VSCode: Added `vscode://anthropic.claude-code/open` URI handler to open a new Claude Code tab programmatically, with optional `prompt` and `session` query parameters
645
646## 2.1.71
647
648- Added `/loop` command to run a prompt or slash command on a recurring interval (e.g. `/loop 5m check the deploy`)
649- Added cron scheduling tools for recurring prompts within a session
650- 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
651- Added `fmt`, `comm`, `cmp`, `numfmt`, `expr`, `test`, `printf`, `getconf`, `seq`, `tsort`, and `pr` to the bash auto-approval allowlist
652- Fixed stdin freeze in long-running sessions where keystrokes stop being processed but the process stays alive
653- Fixed a 5–8 second startup freeze for users with voice mode enabled, caused by CoreAudio initialization blocking the main thread after system wake
654- Fixed startup UI freeze when many claude.ai proxy connectors refresh an expired OAuth token simultaneously
655- Fixed forked conversations (`/fork`) sharing the same plan file, which caused plan edits in one fork to overwrite the other
656- Fixed the Read tool putting oversized images into context when image processing failed, breaking subsequent turns in long image-heavy sessions
657- Fixed false-positive permission prompts for compound bash commands containing heredoc commit messages
658- Fixed plugin installations being lost when running multiple Claude Code instances
659- Fixed claude.ai connectors failing to reconnect after OAuth token refresh
660- Fixed claude.ai MCP connector startup notifications appearing for every org-configured connector instead of only previously connected ones
661- Fixed background agent completion notifications missing the output file path, which made it difficult for parent agents to recover agent results after context compaction
662- Fixed duplicate output in Bash tool error messages when commands exit with non-zero status
663- Fixed Chrome extension auto-detection getting permanently stuck on "not installed" after running on a machine without local Chrome
664- Fixed `/plugin marketplace update` failing with merge conflicts when the marketplace is pinned to a branch/tag ref
665- Fixed `/plugin marketplace add owner/repo@ref` incorrectly parsing `@` — previously only `#` worked as a ref separator, causing undiagnosable errors with `strictKnownMarketplaces`
666- Fixed duplicate entries in `/permissions` Workspace tab when the same directory is added with and without a trailing slash
667- Fixed `--print` hanging forever when team agents are configured — the exit loop no longer waits on long-lived `in_process_teammate` tasks
668- Fixed "❯ Tool loaded." appearing in the REPL after every `ToolSearch` call
669- Fixed prompting for `cd <cwd> && git ...` on Windows when the model uses a mingw-style path
670- Improved startup time by deferring native image processor loading to first use
671- Improved bridge session reconnection to complete within seconds after laptop wake from sleep, instead of waiting up to 10 minutes
672- 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
673- 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.
674- Updated `/debug` to toggle debug logging on mid-session, since debug logs are no longer written by default
675- Removed startup notification noise for unauthenticated org-registered claude.ai connectors
676
677## 2.1.70
678
679- 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
680- 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
681- 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
682- Fixed prompt-cache bust when an MCP server with `instructions` connects after the first turn
683- Fixed Enter inserting a newline instead of submitting when typing over a slow SSH connection
684- Fixed clipboard corrupting non-ASCII text (CJK, emoji) on Windows/WSL by using PowerShell `Set-Clipboard`
685- Fixed extra VS Code windows opening at startup on Windows when running from the VS Code integrated terminal
686- Fixed voice mode failing on Windows native binary with "native audio module could not be loaded"
687- Fixed push-to-talk not activating on session start when `voiceEnabled: true` was set in settings
688- Fixed markdown links containing `#NNN` references incorrectly pointing to the current repository instead of the linked URL
689- Fixed repeated "Model updated to Opus 4.6" notification when a project's `.claude/settings.json` has a legacy Opus model string pinned
690- Fixed plugins showing as inaccurately installed in `/plugin`
691- Fixed plugins showing "not found in marketplace" errors on fresh startup by auto-refreshing after marketplace installation
692- Fixed `/security-review` command failing with `unknown option merge-base` on older git versions
693- Fixed `/color` command having no way to reset back to the default color — `/color default`, `/color gray`, `/color reset`, and `/color none` now restore the default
694- Fixed a performance regression in the `AskUserQuestion` preview dialog that re-ran markdown rendering on every keystroke in the notes input
695- Fixed feature flags read during early startup never refreshing their disk cache, causing stale values to persist across sessions
696- Fixed `permissions.defaultMode` settings values other than `acceptEdits` or `plan` being applied in Claude Code Remote environments — they are now ignored
697- Fixed skill listing being re-injected on every `--resume` (~600 tokens saved per resume)
698- Fixed teleport marker not rendering in VS Code teleported sessions
699- Improved error message when microphone captures silence to distinguish from "no speech detected"
700- Improved compaction to preserve images in the summarizer request, allowing prompt cache reuse for faster and cheaper compaction
701- Improved `/rename` to work while Claude is processing, instead of being silently queued
702- Reduced prompt input re-renders during turns by ~74%
703- Reduced startup memory by ~426KB for users without custom CA certificates
704- 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.
705- [VSCode] Added spark icon in VS Code activity bar that lists all Claude Code sessions, with sessions opening as full editors
706- [VSCode] Added full markdown document view for plans in VS Code, with support for adding comments to provide feedback
707- [VSCode] Added native MCP server management dialog — use `/mcp` in the chat panel to enable/disable servers, reconnect, and manage OAuth authentication without switching to the terminal
708
709## 2.1.69
710
711- Added the `/claude-api` skill for building applications with the Claude API and Anthropic SDK
712- Added Ctrl+U on an empty bash prompt (`!`) to exit bash mode, matching `escape` and `backspace`
713- Added numeric keypad support for selecting options in Claude's interview questions (previously only the number row above QWERTY worked)
714- Added optional name argument to `/remote-control` and `claude remote-control` (`/remote-control My Project` or `--name "My Project"`) to set a custom session title visible in claude.ai/code
715- Added Voice STT support for 10 new languages (20 total) — Russian, Polish, Turkish, Dutch, Ukrainian, Greek, Czech, Danish, Swedish, Norwegian
716- Added effort level display (e.g., "with low effort") to the logo and spinner, making it easier to see which effort setting is active
717- Added agent name display in terminal title when using `claude --agent`
718- Added `sandbox.enableWeakerNetworkIsolation` setting (macOS only) to allow Go programs like `gh`, `gcloud`, and `terraform` to verify TLS certificates when using a custom MITM proxy with `httpProxyPort`
719- Added `includeGitInstructions` setting (and `CLAUDE_CODE_DISABLE_GIT_INSTRUCTIONS` env var) to remove built-in commit and PR workflow instructions from Claude's system prompt
720- Added `/reload-plugins` command to activate pending plugin changes without restarting
721- Added a one-time startup prompt suggesting Claude Code Desktop on macOS and Windows (max 3 showings, dismissible)
722- Added `${CLAUDE_SKILL_DIR}` variable for skills to reference their own directory in SKILL.md content
723- Added `InstructionsLoaded` hook event that fires when CLAUDE.md or `.claude/rules/*.md` files are loaded into context
724- Added `agent_id` (for subagents) and `agent_type` (for subagents and `--agent`) to hook events
725- Added `worktree` field to status line hook commands with name, path, branch, and original repo directory when running in a `--worktree` session
726- Added `pluginTrustMessage` in managed settings to append organization-specific context to the plugin trust warning shown before installation
727- Added policy limit fetching (e.g., remote control restrictions) for Team plan OAuth users, not just Enterprise
728- Added `pathPattern` to `strictKnownMarketplaces` for regex-matching file/directory marketplace sources alongside `hostPattern` restrictions
729- Added plugin source type `git-subdir` to point to a subdirectory within a git repo
730- Added `oauth.authServerMetadataUrl` config option for MCP servers to specify a custom OAuth metadata discovery URL when standard discovery fails
731- Fixed a security issue where nested skill discovery could load skills from gitignored directories like `node_modules`
732- Fixed trust dialog silently enabling all `.mcp.json` servers on first run. You'll now see the per-server approval dialog as expected
733- Fixed `claude remote-control` crashing immediately on npm installs with "bad option: --sdk-url" (anthropics/claude-code#28334)
734- Fixed `--model claude-opus-4-0` and `--model claude-opus-4-1` resolving to deprecated Opus versions instead of current
735- 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.
736- Fixed `.credentials.json` losing `subscriptionType` (showing "Claude API" instead of "Claude Pro"/"Claude Max") when the profile endpoint transiently fails during token refresh (anthropics/claude-code#30185)
737- Fixed ghost dotfiles (`.bashrc`, `HEAD`, etc.) appearing as untracked files in the working directory after sandboxed Bash commands on Linux
738- Fixed Shift+Enter printing `[27;2;13~` instead of inserting a newline in Ghostty over SSH
739- Fixed stash (Ctrl+S) being cleared when submitting a message while Claude is working
740- Fixed ctrl+o (transcript toggle) freezing for many seconds in long sessions with lots of file edits
741- Fixed plan mode feedback input not supporting multi-line text entry (backslash+Enter and Shift+Enter now insert newlines)
742- Fixed cursor not moving down into blank lines at the top of the input box
743- Fixed `/stats` crash when transcript files contain entries with missing or malformed timestamps
744- Fixed a brief hang after a streaming error on long sessions (the transcript was being fully rewritten to drop one line; it is now truncated in place)
745- Fixed `--setting-sources user` not blocking dynamically discovered project skills
746- Fixed duplicate CLAUDE.md, slash commands, agents, and rules when running from a worktree nested inside its main repo (e.g. `claude -w`)
747- Fixed plugin Stop/SessionEnd/etc hooks not firing after any `/plugin` operation
748- Fixed plugin hooks being silently dropped when two plugins use the same `${CLAUDE_PLUGIN_ROOT}/...` command template
749- Fixed memory leak in long-running SDK/CCR sessions where conversation messages were retained unnecessarily
750- Fixed API 400 errors in forked agents (autocompact, summarization) when resuming sessions that were interrupted mid-tool-batch
751- Fixed "unexpected tool_use_id found in tool_result blocks" error when resuming conversations that start with an orphaned tool result
752- Fixed teammates accidentally spawning nested teammates via the Agent tool's `name` parameter
753- Fixed `CLAUDE_CODE_MAX_OUTPUT_TOKENS` being ignored during conversation compaction
754- Fixed `/compact` summary rendering as a user bubble in SDK consumers (Claude Code Remote web UI, VSCode extension)
755- Fixed voice space bar getting stuck after a failed voice activation (module loading race, cold GrowthBook)
756- Fixed worktree file copy on Windows
757- Fixed global `.claude` folder detection on Windows
758- Fixed symlink bypass where writing new files through a symlinked parent directory could escape the working directory in `acceptEdits` mode
759- Fixed sandbox prompting users to approve non-allowed domains when `allowManagedDomainsOnly` is enabled in managed settings — non-allowed domains are now blocked automatically with no bypass
760- Fixed interactive tools (e.g., `AskUserQuestion`) being silently auto-allowed when listed in a skill's allowed-tools, bypassing the permission prompt and running with empty answers
761- Fixed multi-GB memory spike when committing with large untracked binary files in the working tree
762- Fixed Escape not interrupting a running turn when the input box has draft text. Use Up arrow to pull queued messages back for editing, or Ctrl+U to clear the input line.
763- Fixed Android app crash when running local slash commands (`/voice`, `/cost`) in Remote Control sessions
764- Fixed a memory leak where old message array versions accumulated in React Compiler `memoCache` over long sessions
765- Fixed a memory leak where REPL render scopes accumulated over long sessions (~35MB over 1000 turns)
766- Fixed memory retention in in-process teammates where the parent's full conversation history was pinned for the teammate's lifetime, preventing GC after `/clear` or auto-compact
767- Fixed a memory leak in interactive mode where hook events could accumulate unboundedly during long sessions
768- Fixed hang when `--mcp-config` points to a corrupted file
769- Fixed slow startup when many skills/plugins are installed
770- Fixed `cd <outside-dir> && <cmd>` permission prompt to surface the chained command instead of only showing "Yes, allow reading from <dir>/"
771- Fixed conditional `.claude/rules/*.md` files (with `paths:` frontmatter) and nested CLAUDE.md files not loading in print mode (`claude -p`)
772- Fixed `/clear` not fully clearing all session caches, reducing memory retention in long sessions
773- Fixed terminal flicker caused by animated elements at the scrollback boundary
774- Fixed UI frame drops on macOS when using MCP servers with OAuth (regression from 2.1.x)
775- Fixed occasional frame stalls during typing caused by synchronous debug log flushes
776- Fixed `TeammateIdle` and `TaskCompleted` hooks to support `{"continue": false, "stopReason": "..."}` to stop the teammate, matching `Stop` hook behavior
777- Fixed `WorktreeCreate` and `WorktreeRemove` plugin hooks being silently ignored
778- Fixed skill descriptions with colons (e.g., "Triggers include: X, Y, Z") failing to load from SKILL.md frontmatter
779- Fixed project skills without a `description:` frontmatter field not appearing in Claude's available skills list
780- Fixed `/context` showing identical token counts for all MCP tools from a server
781- Fixed literal `nul` file creation on Windows when the model uses CMD-style `2>nul` redirection in Git Bash
782- Fixed extra blank lines appearing below each tool call in the expanded subagent transcript view (Ctrl+O)
783- Fixed Tab/arrow keys not cycling Settings tabs when `/config` search box is focused but empty
784- Fixed service key OAuth sessions (CCR containers) spamming `[ERROR]` logs with 403s from profile-scoped endpoints
785- Fixed inconsistent color for "Remote Control active" status indicator
786- Fixed Voice waveform cursor covering the first suffix letter when dictating mid-input
787- Fixed Voice input showing all 5 spaces during warmup instead of capping at ~2 (aligning with the "keep holding…" hint)
788- Improved spinner performance by isolating the 50ms animation loop from the surrounding shell, reducing render and CPU overhead during turns
789- Improved UI rendering performance in native binaries with React Compiler
790- Improved `--worktree` startup by eliminating a git subprocess on the startup path
791- Improved macOS startup by eliminating redundant settings-file reloads when managed settings resolve
792- Improved macOS startup for Claude.ai enterprise/team users by skipping an unnecessary keychain lookup
793- Improved MCP `-p` startup by pipelining claude.ai config fetch with local connections and using a concurrency pool instead of sequential batching
794- Improved voice startup by removing imperceptible warmup pulse animations that were causing re-render stutter
795- Improved MCP binary content handling: tools returning PDFs, Office documents, or audio now save decoded bytes to disk with the correct file extension instead of dumping raw base64 into the conversation context. WebFetch also saves binary responses alongside its summary.
796- Improved memory usage in long sessions by stabilizing `onSubmit` across message updates
797- Improved LSP tool rendering and memory context building to no longer read entire files
798- Improved session upload and memory sync to avoid reading large files into memory before size/binary checks
799- Improved file operation performance by avoiding reading file contents for existence checks (6 sites)
800- Improved documentation to clarify that `--append-system-prompt-file` and `--system-prompt-file` work in interactive mode (the docs previously said print mode only)
801- Reduced baseline memory by ~16MB by deferring Yoga WASM preloading
802- Reduced memory footprint for SDK and CCR sessions using stream-json output
803- Reduced memory usage when resuming large sessions (including compacted history)
804- Reduced token usage on multi-agent tasks with more concise subagent final reports
805- Changed Sonnet 4.5 users on Pro/Max/Team Premium to be automatically migrated to Sonnet 4.6
806- Changed the `/resume` picker to show your most recent prompt instead of the first one. This also resolves some titles appearing as `(session)`.
807- Changed claude.ai MCP connector failures to show a notification instead of silently disappearing from the tool list
808- Changed example command suggestions to be generated deterministically instead of calling Haiku
809- Changed resuming after compaction to no longer produce a preamble recap before continuing
810- [SDK] Changed task creation to no longer require the `activeForm` field — the spinner falls back to the task subject
811- [VSCode] Added compaction display as a collapsible "Compacted chat" card with the summary inside
812- [VSCode] The permission mode picker now respects `permissions.disableBypassPermissionsMode` from your effective Claude Code settings (including managed/policy settings) — when set to `disable`, bypass permissions mode is hidden from the picker
813- [VSCode] Fixed RTL text (Arabic, Hebrew, Persian) rendering reversed in the chat panel (regression in v2.1.63)
814
815## 2.1.68
816
817- Opus 4.6 now defaults to medium effort for Max and Team subscribers. Medium effort works well for most tasks — it's the sweet spot between speed and thoroughness. You can change this anytime with `/model`
818- Re-introduced the "ultrathink" keyword to enable high effort for the next turn
819- Removed Opus 4 and 4.1 from Claude Code on the first-party API — users with these models pinned are automatically moved to Opus 4.6
820
821## 2.1.66
822
823- Reduced spurious error logging
824
825## 2.1.63
826
827- Added `/simplify` and `/batch` bundled slash commands
828- Fixed local slash command output like /cost appearing as user-sent messages instead of system messages in the UI
829- Project configs & auto memory now shared across git worktrees of the same repository
830- Added `ENABLE_CLAUDEAI_MCP_SERVERS=false` env var to opt out from making claude.ai MCP servers available
831- Improved `/model` command to show the currently active model in the slash command menu
832- Added HTTP hooks, which can POST JSON to a URL and receive JSON instead of running a shell command
833- Fixed listener leak in bridge polling loop
834- Fixed listener leak in MCP OAuth flow cleanup
835- Added manual URL paste fallback during MCP OAuth authentication. If the automatic localhost redirect doesn't work, you can paste the callback URL to complete authentication.
836- Fixed memory leak when navigating hooks configuration menu
837- Fixed listener leak in interactive permission handler during auto-approvals
838- Fixed file count cache ignoring glob ignore patterns
839- Fixed memory leak in bash command prefix cache
840- Fixed MCP tool/resource cache leak on server reconnect
841- Fixed IDE host IP detection cache incorrectly sharing results across ports
842- Fixed WebSocket listener leak on transport reconnect
843- Fixed memory leak in git root detection cache that could cause unbounded growth in long-running sessions
844- Fixed memory leak in JSON parsing cache that grew unbounded over long sessions
845- VSCode: Fixed remote sessions not appearing in conversation history
846- Fixed a race condition in the REPL bridge where new messages could arrive at the server interleaved with historical messages during the initial connection flush, causing message ordering issues.
847- Fixed memory leak where long-running teammates retained all messages in AppState even after conversation compaction
848- Fixed a memory leak where MCP server fetch caches were not cleared on disconnect, causing growing memory usage with servers that reconnect frequently
849- Improved memory usage in long sessions with subagents by stripping heavy progress message payloads during context compaction
850- Added "Always copy full response" option to the `/copy` picker. When selected, future `/copy` commands will skip the code block picker and copy the full response directly.
851- VSCode: Added session rename and remove actions to the sessions list
852- Fixed `/clear` not resetting cached skills, which could cause stale skill content to persist in the new conversation
853
854## 2.1.62
855
856- Fixed prompt suggestion cache regression that reduced cache hit rates
857
858## 2.1.61
859
860- Fixed concurrent writes corrupting config file on Windows
861
862## 2.1.59
863
864- Claude automatically saves useful context to auto-memory. Manage with /memory
865- Added `/copy` command to show an interactive picker when code blocks are present, allowing selection of individual code blocks or the full response.
866- Improved "always allow" prefix suggestions for compound bash commands (e.g. `cd /tmp && git fetch && git push`) to compute smarter per-subcommand prefixes instead of treating the whole command as one
867- Improved ordering of short task lists
868- Improved memory usage in multi-agent sessions by releasing completed subagent task state
869- Fixed MCP OAuth token refresh race condition when running multiple Claude Code instances simultaneously
870- Fixed shell commands not showing a clear error message when the working directory has been deleted
871- Fixed config file corruption that could wipe authentication when multiple Claude Code instances ran simultaneously
872
873## 2.1.58
874
875- Expand Remote Control to more users
876
877## 2.1.56
878
879- VS Code: Fixed another cause of "command 'claude-vscode.editor.openLast' not found" crashes
880
881## 2.1.55
882
883- Fixed BashTool failing on Windows with EINVAL error
884
885## 2.1.53
886
887- Fixed a UI flicker where user input would briefly disappear after submission before the message rendered
888- Fixed bulk agent kill (ctrl+f) to send a single aggregate notification instead of one per agent, and to properly clear the command queue
889- Fixed graceful shutdown sometimes leaving stale sessions when using Remote Control by parallelizing teardown network calls
890- Fixed `--worktree` sometimes being ignored on first launch
891- Fixed a panic ("switch on corrupted value") on Windows
892- Fixed a crash that could occur when spawning many processes on Windows
893- Fixed a crash in the WebAssembly interpreter on Linux x64 & Windows x64
894- Fixed a crash that sometimes occurred after 2 minutes on Windows ARM64
895
896## 2.1.52
897
898- VS Code: Fixed extension crash on Windows ("command 'claude-vscode.editor.openLast' not found")
899
900## 2.1.51
901
902- Added `claude remote-control` subcommand for external builds, enabling local environment serving for all users.
903- Updated plugin marketplace default git timeout from 30s to 120s and added `CLAUDE_CODE_PLUGIN_GIT_TIMEOUT_MS` to configure.
904- Added support for custom npm registries and specific version pinning when installing plugins from npm sources
905- BashTool now skips login shell (`-l` flag) by default when a shell snapshot is available, improving command execution performance. Previously this required setting `CLAUDE_BASH_NO_LOGIN=true`.
906- Fixed a security issue where `statusLine` and `fileSuggestion` hook commands could execute without workspace trust acceptance in interactive mode.
907- Tool results larger than 50K characters are now persisted to disk (previously 100K). This reduces context window usage and improves conversation longevity.
908- Fixed a bug where duplicate `control_response` messages (e.g. from WebSocket reconnects) could cause API 400 errors by pushing duplicate assistant messages into the conversation.
909- Added `CLAUDE_CODE_ACCOUNT_UUID`, `CLAUDE_CODE_USER_EMAIL`, and `CLAUDE_CODE_ORGANIZATION_UUID` environment variables for SDK callers to provide account info synchronously, eliminating a race condition where early telemetry events lacked account metadata.
910- Fixed slash command autocomplete crashing when a plugin's SKILL.md description is a YAML array or other non-string type
911- The `/model` picker now shows human-readable labels (e.g., "Sonnet 4.5") instead of raw model IDs for pinned model versions, with an upgrade hint when a newer version is available.
912- Managed settings can now be set via macOS plist or Windows Registry. Learn more at https://code.claude.com/docs/en/settings#settings-files

917- Added `WorktreeCreate` and `WorktreeRemove` hook events, enabling custom VCS setup and teardown when agent worktree isolation creates or removes worktrees.
918- Fixed a bug where resumed sessions could be invisible when the working directory involved symlinks, because the session storage path was resolved at different times during startup. Also fixed session data loss on SSH disconnect by flushing session data before hooks and analytics in the graceful shutdown sequence.
919- Linux: Fixed native modules not loading on systems with glibc older than 2.30 (e.g., RHEL 8)
920- Fixed memory leak in agent teams where completed teammate tasks were never garbage collected from session state

952- Fixed prompt suggestion cache regression that reduced cache hit rates.
953- Fixed `plugin enable` and `plugin disable` to auto-detect the correct scope when `--scope` is not specified, instead of always defaulting to user scope
954- Simple mode (`CLAUDE_CODE_SIMPLE`) now includes the file edit tool in addition to the Bash tool, allowing direct file editing in simple mode.
955- Permission suggestions are now populated when safety checks trigger an ask response, enabling SDK consumers to display permission options
956- Sonnet 4.5 with 1M context is being removed from the Max plan in favor of our frontier Sonnet 4.6 model, which now has 1M context. Please switch in /model.
957- Fixed verbose mode not updating thinking block display when toggled via `/config` — memo comparators now correctly detect verbose changes

962- Fixed unbounded memory growth during long-running sessions caused by Yoga WASM linear memory never shrinking
963- SDK model info now includes `supportsEffort`, `supportedEffortLevels`, and `supportsAdaptiveThinking` fields so consumers can discover model capabilities.
964- Added `ConfigChange` hook event that fires when configuration files change during a session, enabling enterprise security auditing and optional blocking of settings changes.
965- Improved startup performance by caching MCP auth failures to avoid redundant connection attempts
966- Improved startup performance by reducing HTTP calls for analytics token counting
967- Improved startup performance by batching MCP tool token counting into a single API call
968- Fixed `disableAllHooks` setting to respect managed settings hierarchy — non-managed settings can no longer disable managed hooks set by policy (#26637)
969- Fixed `--resume` session picker showing raw XML tags for sessions that start with commands like `/clear`. Now correctly falls through to the session ID fallback.
970- Improved permission prompts for path safety and working directory blocks to show the reason for the restriction instead of a bare prompt with no context
971
972## 2.1.47
973
974- Fixed FileWriteTool line counting to preserve intentional trailing blank lines instead of stripping them with `trimEnd()`.
975- Fixed Windows terminal rendering bugs caused by `os.EOL` (`\r\n`) in display code — line counts now show correct values instead of always showing 1 on Windows.
976- Improved VS Code plan preview: auto-updates as Claude iterates, enables commenting only when the plan is ready for review, and keeps the preview open when rejecting so Claude can revise.
977- 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.
978- 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)
979- Improved memory usage in long-running sessions by releasing API stream buffers, agent context, and skill state after use
980- Improved startup performance by deferring SessionStart hook execution, reducing time-to-interactive by ~500ms.
981- Fixed an issue where bash tool output was silently discarded on Windows when using MSYS2 or Cygwin shells.
982- Improved performance of `@` file mentions - file suggestions now appear faster by pre-warming the index on startup and using session-based caching with background refresh.
983- Improved memory usage by trimming agent task message history after tasks complete
984- Improved memory usage during long agent sessions by eliminating O(n²) message accumulation in progress updates
985- Fixed the bash permission classifier to validate that returned match descriptions correspond to actual input rules, preventing hallucinated descriptions from incorrectly granting permissions
986- Fixed user-defined agents only loading one file on NFS/FUSE filesystems that report zero inodes (anthropics/claude-code#26044)
987- Fixed plugin agent skills silently failing to load when referenced by bare name instead of fully-qualified plugin name (anthropics/claude-code#25834)

989- Windows: Fixed CWD tracking temp files never being cleaned up, causing them to accumulate indefinitely (anthropics/claude-code#17600)
990- Use `ctrl+f` to kill all background agents instead of double-pressing ESC. Background agents now continue running when you press ESC to cancel the main thread, giving you more control over agent lifecycle.
991- Fixed API 400 errors ("thinking blocks cannot be modified") that occurred in sessions with concurrent agents, caused by interleaved streaming content blocks preventing proper message merging.
992- Simplified teammate navigation to use only Shift+Down (with wrapping) instead of both Shift+Up and Shift+Down.
993- Fixed an issue where a single file write/edit error would abort all other parallel file write/edit operations. Independent file mutations now complete even when a sibling fails.
994- Added `last_assistant_message` field to Stop and SubagentStop hook inputs, providing the final assistant response text so hooks can access it without parsing transcript files.
995- Fixed custom session titles set via `/rename` being lost after resuming a conversation (anthropics/claude-code#23610)
996- Fixed collapsed read/search hint text overflowing on narrow terminals by truncating from the start.
997- Fixed an issue where bash commands with backslash-newline continuation lines (e.g., long commands split across multiple lines with `\`) would produce spurious empty arguments, potentially breaking command execution.

999- Fixed MCP servers not appearing in the MCP Management Dialog after deferred loading
1000- Fixed session name persisting in status bar after `/clear` command (anthropics/claude-code#26082)
1001- Fixed crash when a skill's `name` or `description` in SKILL.md frontmatter is a bare number (e.g., `name: 3000`) — the value is now properly coerced to a string (anthropics/claude-code#25837)
1002- Fixed /resume silently dropping sessions when the first message exceeds 16KB or uses array-format content (anthropics/claude-code#25721)
1003- Added `chat:newline` keybinding action for configurable multi-line input (anthropics/claude-code#26075)

1011- Fixed CJK wide characters causing misaligned timestamps and layout elements in the TUI (anthropics/claude-code#26084)
1012- Fixed custom agent `model` field in `.claude/agents/*.md` being ignored when spawning team teammates (anthropics/claude-code#26064)
1013- Fixed plan mode being lost after context compaction, causing the model to switch from planning to implementation mode (anthropics/claude-code#26061)
1014- Fixed `alwaysThinkingEnabled: true` in settings.json not enabling thinking mode on Bedrock and Vertex providers (anthropics/claude-code#26074)
1015- Fixed `tool_decision` OTel telemetry event not being emitted in headless/SDK mode (anthropics/claude-code#26059)
1016- Fixed session name being lost after context compaction — renamed sessions now preserve their custom title through compaction (anthropics/claude-code#26121)
1017- Increased initial session count in resume picker from 10 to 50 for faster session discovery (anthropics/claude-code#26123)

1021- Fixed React crash (error #31) when a skill's `argument-hint` in SKILL.md frontmatter uses YAML sequence syntax (e.g., `[topic: foo | bar]`) — the value is now properly coerced to a string (anthropics/claude-code#25826)
1022- Fixed crash when using `/fork` on sessions that used web search — null entries in search results from transcript deserialization are now handled gracefully (anthropics/claude-code#25811)
1023- Fixed read-only git commands triggering FSEvents file watcher loops on macOS by adding --no-optional-locks flag (anthropics/claude-code#25750)

1035- Fixed spinner showing "0 tokens" counter before any tokens have been received (anthropics/claude-code#26105)
1036- VSCode: Fixed conversation messages appearing dimmed while the AskUserQuestion dialog is open (anthropics/claude-code#26078)
1037- Fixed background tasks failing in git worktrees due to remote URL resolution reading from worktree-specific gitdir instead of the main repository config (anthropics/claude-code#26065)

1149- Fixed an issue where submitting a new message while the model was in extended thinking would interrupt the thinking phase
1150- Fixed an API error that could occur when aborting mid-stream, where whitespace text combined with a thinking block would bypass normalization and produce an invalid request
1151- Fixed API proxy compatibility issue where 404 errors on streaming endpoints no longer triggered non-streaming fallback
1152- Fixed an issue where proxy settings configured via `settings.json` environment variables were not applied to WebFetch and other HTTP requests on the Node.js build

1189## 2.1.30
1190
1191- Added `pages` parameter to the Read tool for PDFs, allowing specific page ranges to be read (e.g., `pages: "1-5"`). Large PDFs (>10 pages) now return a lightweight reference when `@` mentioned instead of being inlined into context.
1192- Added pre-configured OAuth client credentials for MCP servers that don't support Dynamic Client Registration (e.g., Slack). Use `--client-id` and `--client-secret` with `claude mcp add`.
