Automated update of claude-code from 2.1.49 to 2.1.89.

Changelog

2.1.89

• 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
• Added CLAUDE_CODE_NO_FLICKER=1 environment variable to opt into flicker-free alt-screen rendering with virtualized scrollback
• Added PermissionDenied hook that fires after auto mode classifier denials — return {retry: true} to tell the model it can retry
• Added named subagents to @ mention typeahead suggestions
• 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
• Auto mode: denied commands now show a notification and appear in /permissions → Recent tab where you can retry with r
• Fixed Edit(//path/**) and Read(//path/**) allow rules to check the resolved symlink target, not just the requested path
• 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"
• Fixed Edit/Write tools doubling CRLF on Windows and stripping Markdown hard line breaks (two trailing spaces)
• Fixed StructuredOutput schema cache bug causing ~50% failure rate when using multiple schemas
• Fixed memory leak where large JSON inputs were retained as LRU cache keys in long-running sessions
• Fixed a crash when removing a message from very large session files (over 50MB)
• Fixed LSP server zombie state after crash — server now restarts on next request instead of failing until session restart
• Fixed prompt history entries containing CJK or emoji being silently dropped when they fall on a 4KB boundary in ~/.claude/history.jsonl
• Fixed /stats undercounting tokens by excluding subagent usage, and losing historical data beyond 30 days when the stats cache format changes
• Fixed -p --resume hangs when the deferred tool input exceeds 64KB or no deferred marker exists, and -p --continue not resuming deferred tools
• Fixed claude-cli:// deep links not opening on macOS
• Fixed MCP tool errors truncating to only the first content block when the server returns multi-element error content
• Fixed skill reminders and other system context being dropped when sending messages with images via the SDK
• Fixed PreToolUse/PostToolUse hooks to receive file_path as an absolute path for Write/Edit/Read tools, matching the documented behavior
• 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
• Fixed prompt cache misses in long sessions caused by tool schema bytes changing mid-session
• Fixed nested CLAUDE.md files being re-injected dozens of times in long sessions that read many files
• Fixed --resume crash when transcript contains a tool result from an older CLI version or interrupted write
• Fixed misleading "Rate limit reached" message when the API returned an entitlement error — now shows the actual error with actionable hints
• Fixed hooks if condition filtering not matching compound commands (ls && git push) or commands with env-var prefixes (FOO=bar git push)
• Fixed collapsed search/read group badges duplicating in terminal scrollback during heavy parallel tool use
• Fixed notification invalidates not clearing the currently-displayed notification immediately
• Fixed prompt briefly disappearing after submit when background messages arrived during processing

• Fixed a potential out-of-memory crash when the Edit tool was used on very large files (>1 GiB)
• Improved collapsed tool summary to show "Listed N directories" for ls/tree/du instead of "Read N files"
• Improved Bash tool to warn when a formatter/linter command modifies files you have previously read, preventing stale-edit errors
• Improved @-mention typeahead to rank source files above MCP resources with similar names
• Improved PowerShell tool prompt with version-appropriate syntax guidance (5.1 vs 7+)
• Changed Edit to work on files viewed via Bash with sed -n or cat, without requiring a separate Read call first
• Changed hook output over 50K characters to be saved to disk with a file path + preview instead of being injected directly into context
• Changed cleanupPeriodDays: 0 in settings.json to be rejected with a validation error — it previously silently disabled transcript persistence
• Changed thinking summaries to no longer be generated by default in interactive sessions — set showThinkingSummaries: true in settings.json to restore
• Documented TaskCreated hook event and its blocking behavior
• Preserved task notifications when backgrounding a running command with Ctrl+B

• Improved /plugin uninstall to disable project-scoped plugins in .claude/settings.local.json instead of modifying .claude/settings.json, so changes don't affect teammates
• Improved plugin-provided MCP server deduplication — servers that duplicate a manually-configured server (same command/URL) are now skipped, preventing duplicate connections and tool sets. Suppressions are shown in the /plugin menu.
• Updated /debug to toggle debug logging on mid-session, since debug logs are no longer written by default
• Removed startup notification noise for unauthenticated org-registered claude.ai connectors

2.1.70

• Fixed API 400 errors when using ANTHROPIC_BASE_URL with a third-party gateway — tool search now correctly detects proxy endpoints and disables tool_reference blocks
• Fixed API Error: 400 This model does not support the effort parameter when using custom Bedrock inference profiles or other model identifiers not matching standard Claude naming patterns

• Fixed worktree file copy on Windows
• Fixed global .claude folder detection on Windows
• Fixed symlink bypass where writing new files through a symlinked parent directory could escape the working directory in acceptEdits mode
• 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

• Fixed slow startup when many skills/plugins are installed
• Fixed cd <outside-dir> && <cmd> permission prompt to surface the chained command instead of only showing "Yes, allow reading from /"

• Improved UI rendering performance in native binaries with React Compiler
• Improved --worktree startup by eliminating a git subprocess on the startup path
• Improved macOS startup by eliminating redundant settings-file reloads when managed settings resolve
• Improved macOS startup for Claude.ai enterprise/team users by skipping an unnecessary keychain lookup
• Improved MCP -p startup by pipelining claude.ai config fetch with local connections and using a concurrency pool instead of sequential batching
• Improved voice startup by removing imperceptible warmup pulse animations that were causing re-render stutter
• 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.
• Improved memory usage in long sessions by stabilizing onSubmit across message updates
• Improved LSP tool rendering and memory context building to no longer read entire files
• Improved session upload and memory sync to avoid reading large files into memory before size/binary checks

• [VSCode] Added compaction display as a collapsible "Compacted chat" card with the summary inside
• [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
• [VSCode] Fixed RTL text (Arabic, Hebrew, Persian) rendering reversed in the chat panel (regression in v2.1.63)

• Re-introduced the "ultrathink" keyword to enable high effort for the next turn
• 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

2.1.63

• Added /simplify and /batch bundled slash commands
• Fixed local slash command output like /cost appearing as user-sent messages instead of system messages in the UI

• Fixed memory leak in JSON parsing cache that grew unbounded over long sessions
• VSCode: Fixed remote sessions not appearing in conversation history
• 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.
• Fixed memory leak where long-running teammates retained all messages in AppState even after conversation compaction
• Fixed a memory leak where MCP server fetch caches were not cleared on disconnect, causing growing memory usage with servers that reconnect frequently
• Improved memory usage in long sessions with subagents by stripping heavy progress message payloads during context compaction
• 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.
• VSCode: Added session rename and remove actions to the sessions list
• Fixed /clear not resetting cached skills, which could cause stale skill content to persist in the new conversation

2.1.62

• Fixed prompt suggestion cache regression that reduced cache hit rates

2.1.61

• Fixed concurrent writes corrupting config file on Windows

2.1.59

• Fixed BashTool failing on Windows with EINVAL error

2.1.53

• Fixed a UI flicker where user input would briefly disappear after submission before the message rendered

• 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.
• Fixed a security issue where statusLine and fileSuggestion hook commands could execute without workspace trust acceptance in interactive mode.
• Tool results larger than 50K characters are now persisted to disk (previously 100K). This reduces context window usage and improves conversation longevity.

• 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.
• Fixed slash command autocomplete crashing when a plugin's SKILL.md description is a YAML array or other non-string type
• 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.
• Managed settings can now be set via macOS plist or Windows Registry. Learn more at https://code.claude.com/docs/en/settings#settings-files

2.1.50

• Added support for startupTimeout configuration for LSP servers
• Added WorktreeCreate and WorktreeRemove hook events, enabling custom VCS setup and teardown when agent worktree isolation creates or removes worktrees.

Reconnection is unaffected — transport loss immediately wakes fast polling. - [VSCode] Added spark icon in VS Code activity bar that lists all Claude Code sessions, with sessions opening as full editors - [VSCode] Added full markdown document view for plans in VS Code, with support for adding comments to provide feedback - [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 ## 2.1.69 - Added the `/claude-api` skill for building applications with the Claude API and Anthropic SDK - Added Ctrl+U on an empty bash prompt (`!`) to exit bash mode, matching `escape` and `backspace` - Added numeric keypad support for selecting options in Claude's interview questions (previously only the number row above QWERTY worked) - 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 - Added Voice STT support for 10 new languages (20 total) — Russian, Polish, Turkish, Dutch, Ukrainian, Greek, Czech, Danish, Swedish, Norwegian - Added effort level display (e.g., "with low effort") to the logo and spinner, making it easier to see which effort setting is active - Added agent name display in terminal title when using `claude --agent` - 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` - 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 - Added `/reload-plugins` command to activate pending plugin changes without restarting - Added a one-time startup prompt suggesting Claude Code Desktop on macOS and Windows (max 3 showings, dismissible) - Added `${CLAUDE_SKILL_DIR}` variable for skills to reference their own directory in SKILL.md content - Added `InstructionsLoaded` hook event that fires when CLAUDE.md or `.claude/rules/*.md` files are loaded into context - Added `agent_id` (for subagents) and `agent_type` (for subagents and `--agent`) to hook events - Added `worktree` field to status line hook commands with name, path, branch, and original repo directory when running in a `--worktree` session - Added `pluginTrustMessage` in managed settings to append organization-specific context to the plugin trust warning shown before installation - Added policy limit fetching (e.g., remote control restrictions) for Team plan OAuth users, not just Enterprise - Added `pathPattern` to `strictKnownMarketplaces` for regex-matching file/directory marketplace sources alongside `hostPattern` restrictions - Added plugin source type `git-subdir` to point to a subdirectory within a git repo - Added `oauth.authServerMetadataUrl` config option for MCP servers to specify a custom OAuth metadata discovery URL when standard discovery fails - Fixed a security issue where nested skill discovery could load skills from gitignored directories like `node_modules` - Fixed trust dialog silently enabling all `.mcp.json` servers on first run. You'll now see the per-server approval dialog as expected - Fixed `claude remote-control` crashing immediately on npm installs with "bad option: --sdk-url" (anthropics/claude-code#28334) - Fixed `--model claude-opus-4-0` and `--model claude-opus-4-1` resolving to deprecated Opus versions instead of current - Fixed macOS keychain corruption when using multiple OAuth MCP servers. Large OAuth metadata blobs could overflow the `security -i` stdin buffer, silently leaving stale credentials behind and causing repeated `/login` prompts. - Fixed `.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) - Fixed ghost dotfiles (`.bashrc`, `HEAD`, etc.) appearing as untracked files in the working directory after sandboxed Bash commands on Linux - Fixed Shift+Enter printing `[27;2;13~` instead of inserting a newline in Ghostty over SSH - Fixed stash (Ctrl+S) being cleared when submitting a message while Claude is working - Fixed ctrl+o (transcript toggle) freezing for many seconds in long sessions with lots of file edits - Fixed plan mode feedback input not supporting multi-line text entry (backslash+Enter and Shift+Enter now insert newlines) - Fixed cursor not moving down into blank lines at the top of the input box - Fixed `/stats` crash when transcript files contain entries with missing or malformed timestamps - 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) - Fixed `--setting-sources user` not blocking dynamically discovered project skills - Fixed duplicate CLAUDE.md, slash commands, agents, and rules when running from a worktree nested inside its main repo (e.g. `claude -w`) - Fixed plugin Stop/SessionEnd/etc hooks not firing after any `/plugin` operation - Fixed plugin hooks being silently dropped when two plugins use the same `${CLAUDE_PLUGIN_ROOT}/...` command template - Fixed memory leak in long-running SDK/CCR sessions where conversation messages were retained unnecessarily - Fixed API 400 errors in forked agents (autocompact, summarization) when resuming sessions that were interrupted mid-tool-batch - Fixed "unexpected tool_use_id found in tool_result blocks" error when resuming conversations that start with an orphaned tool result - Fixed teammates accidentally spawning nested teammates via the Agent tool's `name` parameter - Fixed `CLAUDE_CODE_MAX_OUTPUT_TOKENS` being ignored during conversation compaction - Fixed `/compact` summary rendering as a user bubble in SDK consumers (Claude Code Remote web UI, VSCode extension) - Fixed voice space bar getting stuck after a failed voice activation (module loading race, cold GrowthBook) - Fixed worktree file copy on Windows - Fixed global `.claude` folder detection on Windows - Fixed symlink bypass where writing new files through a symlinked parent directory could escape the working directory in `acceptEdits` mode - 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 - 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 - Fixed multi-GB memory spike when committing with large untracked binary files in the working tree - 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. - Fixed Android app crash when running local slash commands (`/voice`, `/cost`) in Remote Control sessions - Fixed a memory leak where old message array versions accumulated in React Compiler `memoCache` over long sessions - Fixed a memory leak where REPL render scopes accumulated over long sessions (~35MB over 1000 turns) - 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 - Fixed a memory leak in interactive mode where hook events could accumulate unboundedly during long sessions - Fixed hang when `--mcp-config` points to a corrupted file - Fixed slow startup when many skills/plugins are installed - Fixed `cd <outside-dir> && <cmd>` permission prompt to surface the chained command instead of only showing "Yes, allow reading from <dir>/" - Fixed conditional `.claude/rules/*.md` files (with `paths:` frontmatter) and nested CLAUDE.md files not loading in print mode (`claude -p`) - Fixed `/clear` not fully clearing all session caches, reducing memory retention in long sessions - Fixed terminal flicker caused by animated elements at the scrollback boundary - Fixed UI frame drops on macOS when using MCP servers with OAuth (regression from 2.1.x) - Fixed occasional frame stalls during typing caused by synchronous debug log flushes - Fixed `TeammateIdle` and `TaskCompleted` hooks to support `{"continue": false, "stopReason": "..."}` to stop the teammate, matching `Stop` hook behavior - Fixed `WorktreeCreate` and `WorktreeRemove` plugin hooks being silently ignored - Fixed skill descriptions with colons (e.g., "Triggers include: X, Y, Z") failing to load from SKILL.md frontmatter - Fixed project skills without a `description:` frontmatter field not appearing in Claude's available skills list - Fixed `/context` showing identical token counts for all MCP tools from a server - Fixed literal `nul` file creation on Windows when the model uses CMD-style `2>nul` redirection in Git Bash - Fixed extra blank lines appearing below each tool call in the expanded subagent transcript view (Ctrl+O) - Fixed Tab/arrow keys not cycling Settings tabs when `/config` search box is focused but empty - Fixed service key OAuth sessions (CCR containers) spamming `[ERROR]` logs with 403s from profile-scoped endpoints - Fixed inconsistent color for "Remote Control active" status indicator - Fixed Voice waveform cursor covering the first suffix letter when dictating mid-input - Fixed Voice input showing all 5 spaces during warmup instead of capping at ~2 (aligning with the "keep holding…" hint) - Improved spinner performance by isolating the 50ms animation loop from the surrounding shell, reducing render and CPU overhead during turns - Improved UI rendering performance in native binaries with React Compiler - Improved `--worktree` startup by eliminating a git subprocess on the startup path - Improved macOS startup by eliminating redundant settings-file reloads when managed settings resolve - Improved macOS startup for Claude.ai enterprise/team users by skipping an unnecessary keychain lookup - Improved MCP `-p` startup by pipelining claude.ai config fetch with local connections and using a concurrency pool instead of sequential batching - Improved voice startup by removing imperceptible warmup pulse animations that were causing re-render stutter - 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. - Improved memory usage in long sessions by stabilizing `onSubmit` across message updates - Improved LSP tool rendering and memory context building to no longer read entire files - Improved session upload and memory sync to avoid reading large files into memory before size/binary checks - Improved file operation performance by avoiding reading file contents for existence checks (6 sites) - Improved documentation to clarify that `--append-system-prompt-file` and `--system-prompt-file` work in interactive mode (the docs previously said print mode only) - Reduced baseline memory by ~16MB by deferring Yoga WASM preloading - Reduced memory footprint for SDK and CCR sessions using stream-json output - Reduced memory usage when resuming large sessions (including compacted history) - Reduced token usage on multi-agent tasks with more concise subagent final reports - Changed Sonnet 4.5 users on Pro/Max/Team Premium to be automatically migrated to Sonnet 4.6 - Changed the `/resume` picker to show your most recent prompt instead of the first one. This also resolves some titles appearing as `(session)`. - Changed claude.ai MCP connector failures to show a notification instead of silently disappearing from the tool list - Changed example command suggestions to be generated deterministically instead of calling Haiku - Changed resuming after compaction to no longer produce a preamble recap before continuing - [SDK] Changed task creation to no longer require the `activeForm` field — the spinner falls back to the task subject - [VSCode] Added compaction display as a collapsible "Compacted chat" card with the summary inside - [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 - [VSCode] Fixed RTL text (Arabic, Hebrew, Persian) rendering reversed in the chat panel (regression in v2.1.63) ## 2.1.68 - 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` - Re-introduced the "ultrathink" keyword to enable high effort for the next turn - 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 ## 2.1.66 - Reduced spurious error logging ## 2.1.63 - Added `/simplify` and `/batch` bundled slash commands - Fixed local slash command output like /cost appearing as user-sent messages instead of system messages in the UI - Project configs & auto memory now shared across git worktrees of the same repository - Added `ENABLE_CLAUDEAI_MCP_SERVERS=false` env var to opt out from making claude.ai MCP servers available - Improved `/model` command to show the currently active model in the slash command menu - Added HTTP hooks, which can POST JSON to a URL and receive JSON instead of running a shell command - Fixed listener leak in bridge polling loop - Fixed listener leak in MCP OAuth flow cleanup - 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. - Fixed memory leak when navigating hooks configuration menu - Fixed listener leak in interactive permission handler during auto-approvals - Fixed file count cache ignoring glob ignore patterns - Fixed memory leak in bash command prefix cache - Fixed MCP tool/resource cache leak on server reconnect - Fixed IDE host IP detection cache incorrectly sharing results across ports - Fixed WebSocket listener leak on transport reconnect - Fixed memory leak in git root detection cache that could cause unbounded growth in long-running sessions - Fixed memory leak in JSON parsing cache that grew unbounded over long sessions - VSCode: Fixed remote sessions not appearing in conversation history - 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. - Fixed memory leak where long-running teammates retained all messages in AppState even after conversation compaction - Fixed a memory leak where MCP server fetch caches were not cleared on disconnect, causing growing memory usage with servers that reconnect frequently - Improved memory usage in long sessions with subagents by stripping heavy progress message payloads during context compaction - 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. - VSCode: Added session rename and remove actions to the sessions list - Fixed `/clear` not resetting cached skills, which could cause stale skill content to persist in the new conversation ## 2.1.62 - Fixed prompt suggestion cache regression that reduced cache hit rates ## 2.1.61 - Fixed concurrent writes corrupting config file on Windows ## 2.1.59 - Claude automatically saves useful context to auto-memory. Manage with /memory - Added `/copy` command to show an interactive picker when code blocks are present, allowing selection of individual code blocks or the full response. - 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 - Improved ordering of short task lists - Improved memory usage in multi-agent sessions by releasing completed subagent task state - Fixed MCP OAuth token refresh race condition when running multiple Claude Code instances simultaneously - Fixed shell commands not showing a clear error message when the working directory has been deleted - Fixed config file corruption that could wipe authentication when multiple Claude Code instances ran simultaneously ## 2.1.58 - Expand Remote Control to more users ## 2.1.56 - VS Code: Fixed another cause of "command 'claude-vscode.editor.openLast' not found" crashes ## 2.1.55 - Fixed BashTool failing on Windows with EINVAL error ## 2.1.53 - Fixed a UI flicker where user input would briefly disappear after submission before the message rendered - Fixed bulk agent kill (ctrl+f) to send a single aggregate notification instead of one per agent, and to properly clear the command queue - Fixed graceful shutdown sometimes leaving stale sessions when using Remote Control by parallelizing teardown network calls - Fixed `--worktree` sometimes being ignored on first launch - Fixed a panic ("switch on corrupted value") on Windows - Fixed a crash that could occur when spawning many processes on Windows - Fixed a crash in the WebAssembly interpreter on Linux x64 & Windows x64 - Fixed a crash that sometimes occurred after 2 minutes on Windows ARM64 ## 2.1.52 - VS Code: Fixed extension crash on Windows ("command 'claude-vscode.editor.openLast' not found") ## 2.1.51 - Added `claude remote-control` subcommand for external builds, enabling local environment serving for all users. - Updated plugin marketplace default git timeout from 30s to 120s and added `CLAUDE_CODE_PLUGIN_GIT_TIMEOUT_MS` to configure. - Added support for custom npm registries and specific version pinning when installing plugins from npm sources - 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`. - Fixed a security issue where `statusLine` and `fileSuggestion` hook commands could execute without workspace trust acceptance in interactive mode. - Tool results larger than 50K characters are now persisted to disk (previously 100K). This reduces context window usage and improves conversation longevity. - 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. - 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. - Fixed slash command autocomplete crashing when a plugin's SKILL.md description is a YAML array or other non-string type - 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. - Managed settings can now be set via macOS plist or Windows Registry. Learn more at https://code.claude.com/docs/en/settings#settings-files ## 2.1.50 - Added support for `startupTimeout` configuration for LSP servers - Added `WorktreeCreate` and `WorktreeRemove` hook events, enabling custom VCS setup and teardown when agent worktree isolation creates or removes worktrees. - 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. - Linux: Fixed native modules not loading on systems with glibc older than 2.30 (e.g., RHEL 8) - Fixed memory leak in agent teams where completed teammate tasks were never garbage collected from session state - Fixed `CLAUDE_CODE_SIMPLE` to fully strip down skills, session memory, custom agents, and CLAUDE.md token counting - Fixed `/mcp reconnect` freezing the CLI when given a server name that doesn't exist - Fixed memory leak where completed task state objects were never removed from AppState - Added support for `isolation: worktree` in agent definitions, allowing agents to declaratively run in isolated git worktrees. - `CLAUDE_CODE_SIMPLE` mode now also disables MCP tools, attachments, hooks, and CLAUDE.md file loading for a fully minimal experience. - Fixed bug where MCP tools were not discovered when tool search is enabled and a prompt is passed in as a launch argument - Improved memory usage during long sessions by clearing internal caches after compaction - Added `claude agents` CLI command to list all configured agents - Improved memory usage during long sessions by clearing large tool results after they have been processed - Fixed a memory leak where LSP diagnostic data was never cleaned up after delivery, causing unbounded memory growth in long sessions - Fixed a memory leak where completed task output was not freed from memory, reducing memory usage in long sessions with many tasks - Improved startup performance for headless mode (`-p` flag) by deferring Yoga WASM and UI component imports - Fixed prompt suggestion cache regression that reduced cache hit rates - Fixed unbounded memory growth in long sessions by capping file history snapshots - Added `CLAUDE_CODE_DISABLE_1M_CONTEXT` environment variable to disable 1M context window support - Opus 4.6 (fast mode) now includes the full 1M context window - VSCode: Added `/extra-usage` command support in VS Code sessions - Fixed memory leak where TaskOutput retained recent lines after cleanup - Fixed memory leak in CircularBuffer where cleared items were retained in the backing array - Fixed memory leak in shell command execution where ChildProcess and AbortController references were retained after cleanup
