2.1.133

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

• Fixed Read/Write/Edit being denied on mapped network drives passed via --add-dir / SDK additionalDirectories
• Fixed Remote Control stop/interrupt from claude.ai not fully canceling the CLI session the same way local Esc does, causing queued messages to never advance after interrupting a stuck tool or prompt
• Fixed /effort in one session unexpectedly changing the effort level of other concurrent sessions, and a related issue where an IDE effort change could be silently dropped
• Fixed subagents not discovering project, user, or plugin skills via the Skill tool

2.1.132

• Added CLAUDE_CODE_SESSION_ID environment variable to the Bash tool subprocess environment, matching the session_id passed to hooks
• Added CLAUDE_CODE_DISABLE_ALTERNATE_SCREEN=1 env var to opt out of the fullscreen alternate-screen renderer and keep the conversation in the terminal's native scrollback
• Added a "Pasting…" footer hint while a Ctrl+V image paste is being read from the clipboard
• Fixed external SIGINT (e.g. IDE stop button, kill -INT) not running graceful shutdown — terminal modes are now restored and the --resume hint is printed instead of an abrupt exit
• Fixed an uncaught exception when the terminal is closed or SSH disconnects mid-session under the native build
• Fixed --resume failing with no low surrogate in string when a tool error truncation split an emoji; pre-corrupted sessions are sanitized on load

• Fixed mouse wheel scrolling being too fast in Cursor and VS Code 1.92–1.104 due to an upstream xterm.js bug
• Fixed scroll-wheel handling in JetBrains IDE 2025.2 terminals (spurious arrow keys, wrong-direction events, runaway acceleration)
• Fixed /usage Ctrl+S hanging when copying the stats screenshot to the clipboard on Linux/X11

2.1.129

• Added --plugin-url <url> flag to fetch a plugin .zip archive from a URL for the current session
• Added CLAUDE_CODE_FORCE_SYNC_OUTPUT=1 env var to force-enable synchronized output on terminals that auto-detection misses (e.g. Emacs eat)
• Added CLAUDE_CODE_PACKAGE_MANAGER_AUTO_UPDATE: when set on Homebrew or WinGet installations, Claude Code runs the upgrade command in the background and prompts to restart
• Plugin manifests: themes and monitors should now be declared under "experimental": { ... }. Top-level declarations still work but claude plugin validate will warn
• Gateway /v1/models discovery for the /model picker is now opt-in via CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY=1 (was automatic in 2.1.126–2.1.128)
• Ctrl+R history picker now defaults to searching all prompts across all projects, matching pre-2.1.124 behavior. Press Ctrl+S to narrow to the current project or session
• Third-party deployments (Bedrock, Vertex, Foundry, or ANTHROPIC_BASE_URL gateway) no longer see spinner tips pointing at first-party Anthropic surfaces
• skillOverrides setting now works: off hides from model and /, user-invocable-only hides from model only, name-only collapses description
• The claude_code.pull_request.count OTel metric now counts PRs/MRs created via MCP tools, not just shell commands

• Fixed /branch success message not including the new branch's session id for /resume
• Fixed bold headers with keycap/ZWJ/skin-tone emoji losing trailing characters in fullscreen mode

• Fixed 1-hour prompt cache TTL being silently downgraded to 5 minutes
• Fixed cache-miss warning appearing spuriously after /clear or compaction when changing /effort or /model

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

• Fixed MCP tool results dropping images when the server returns both structured content and content blocks
• Fixed fenced code blocks inside list items carrying leading whitespace into the clipboard on copy-paste

• Fixed sessions on 1M-context models with a smaller autocompact window being falsely blocked with "Prompt is too long" before reaching the actual API limit
• Fixed parallel shell tool calls: a failing read-only command (grep, git diff, ls) no longer cancels sibling calls
• Fixed banner showing "with X effort" on models that don't support effort
• Fixed /fast on 3P providers fuzzy-matching to an unrelated skill instead of showing "not available"
• Fixed Bedrock default model resolving to global.* instead of the region-appropriate prefix
• Fixed vim mode: Space in NORMAL mode now moves the cursor right, matching standard vi/vim behavior
• Fixed terminal progress indicator (OSC 9;4) flickering off between tool calls — stays visible across the full turn
• Fixed /rename without args failing on resumed sessions whose last entry is a compact boundary
• Fixed stale "remote-control is active" status lines from prior sessions appearing after --resume/--continue
• Fixed stale installed_plugins.json entries pointing at deleted cache directories polluting PATH
• Fixed MCP stdio servers receiving corrupted arguments when CLAUDE_CODE_SHELL_PREFIX is set and an argument contains spaces or shell metacharacters
• Fixed sub-agent progress summaries missing the prompt cache (~3× cache_creation reduction)
• Fixed /plugin update never detecting new versions of npm-sourced plugins
• Fixed sub-agent summaries firing repeatedly while a sub-agent's transcript is static, capping worst-case token cost on idle sub-agents
• Headless --output-format stream-json: init.plugin_errors now includes --plugin-dir load failures in addition to dependency demotions

2.1.126

• The /model picker now lists models from your gateway's /v1/models endpoint when ANTHROPIC_BASE_URL points at an Anthropic-compatible gateway
• - Added claude project purge [path] to delete all Claude Code state for a project (transcripts, tasks, file history, config entry) — supports --dry-run, -y/--yes, -i/--interactive, and --all
• --dangerously-skip-permissions now bypasses prompts for writes to .claude/, .git/, .vscode/, shell config files, and other previously-protected paths (catastrophic removal commands still prompt as a safety net)
• claude auth login now accepts the OAuth code pasted into the terminal when the browser callback can't reach localhost (WSL2, SSH, containers)
• claude_code.skill_activated OpenTelemetry event now fires for user-typed slash commands and carries a new invocation_trigger attribute ("user-slash", "claude-proactive", or "nested-skill")
• Auto mode: the spinner now turns red when a permission check stalls, instead of looking like the tool is running
• Host-managed deployments (CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST) no longer auto-disable analytics on Bedrock/Vertex/Foundry

• Security: Fixed allowManagedDomainsOnly / allowManagedReadPathsOnly being ignored when a higher-priority managed-settings source lacked a sandbox block
• Fixed pasting an image larger than 2000px breaking the session — images are now downscaled on paste, and oversized images in history are automatically removed and the request retried
• Fixed showing the login screen for "OAuth not allowed for organization" errors — now shows guidance to contact your admin
• Fixed OAuth login failing with timeout on slow or proxied connections, in IPv6-only devcontainers, and when the browser callback can't reach localhost
• Fixed a rare race where a concurrent credential write could clear a valid OAuth refresh token
• Fixed API retry countdown sticking at "0s" instead of counting down between attempts

• Fixed claude.ai MCP connectors being suppressed by manual servers stuck in needs-auth state
• Fixed Japanese/Korean/Chinese text rendering as garbled characters on Windows in no-flicker mode

• Pasting a PR URL into the /resume search box now finds the session that created that PR (GitHub, GitHub Enterprise, GitLab, and Bitbucket)
• /mcp now shows claude.ai connectors hidden by a manually-added server with the same URL, with a hint to remove the duplicate
• Clarified the /mcp message shown when an MCP server is still unauthorized after the browser sign-in flow

• Fixed feedback survey appearing too frequently in long sessions
• Fixed --effort CLI flag being reset by unrelated settings writes on startup
• Fixed backgrounded Ctrl+B queries losing their transcript or corrupting the new conversation after /clear

2.1.71

• Added /loop command to run a prompt or slash command on a recurring interval (e.g. /loop 5m check the deploy)
• Added cron scheduling tools for recurring prompts within a session
• Added voice:pushToTalk keybinding to make the voice activation key rebindable in keybindings.json (default: space) — modifier+letter combos like meta+k have zero typing interference
• Added fmt, comm, cmp, numfmt, expr, test, printf, getconf, seq, tsort, and pr to the bash auto-approval allowlist
• Fixed stdin freeze in long-running sessions where keystrokes stop being processed but the process stays alive

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

2.1.70

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

• Fixed /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
• Fixed a performance regression in the AskUserQuestion preview dialog that re-ran markdown rendering on every keystroke in the notes input
• Fixed feature flags read during early startup never refreshing their disk cache, causing stale values to persist across sessions

• 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 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

• 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)

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

• 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

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

• 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.

• 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.

• Improved startup performance by caching MCP auth failures to avoid redundant connection attempts
• Improved startup performance by reducing HTTP calls for analytics token counting
• Improved startup performance by batching MCP tool token counting into a single API call
• Fixed disableAllHooks setting to respect managed settings hierarchy — non-managed settings can no longer disable managed hooks set by policy (#26637)
• 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.
• 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

2.1.47

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