v2.1.83

What's changed

• Fixed session crashes in Desktop/SDK when Read returned files containing U+2028/U+2029 characters
• Fixed terminal title being cleared on exit even when CLAUDE_CODE_DISABLE_TERMINAL_TITLE was set

v2.1.71

What's changed

• Added /loop command to run a prompt or slash command on a recurring interval (e.g. /loop 5m check the deploy)

• Fixed Chrome extension auto-detection getting permanently stuck on "not installed" after running on a machine without local Chrome
• Fixed /plugin marketplace update failing with merge conflicts when the marketplace is pinned to a branch/tag ref

• Fixed --print hanging forever when team agents are configured — the exit loop no longer waits on long-lived in_process_teammate tasks
• Fixed "❯ Tool loaded." appearing in the REPL after every ToolSearch call
• Fixed prompting for cd <cwd> && git ... on Windows when the model uses a mingw-style path
• 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

v2.1.70

What's changed

• 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 prompt-cache bust when an MCP server with instructions connects after the first turn
• Fixed Enter inserting a newline instead of submitting when typing over a slow SSH connection
• Fixed clipboard corrupting non-ASCII text (CJK, emoji) on Windows/WSL by using PowerShell Set-Clipboard

• 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 permissions.defaultMode settings values other than acceptEdits or plan being applied in Claude Code Remote environments — they are now ignored
• Fixed skill listing being re-injected on every --resume (~600 tokens saved per resume)
• Fixed teleport marker not rendering in VS Code teleported sessions
• Improved error message when microphone captures silence to distinguish from "no speech detected"
• Improved compaction to preserve images in the summarizer request, allowing prompt cache reuse for faster and cheaper compaction
• Improved /rename to work while Claude is processing, instead of being silently queued
• Reduced prompt input re-renders during turns by ~74%
• Reduced startup memory by ~426KB for users without custom CA certificates
• 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.
• [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

v2.1.69

What's changed

• 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

• 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 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 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 /"
• 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 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)

• [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)

v2.1.68

What's changed

• 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

v2.1.66

v2.1.63

• 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

v2.1.62

What's changed

v2.1.61

What's changed

• Fixed concurrent writes corrupting config file on Windows

v2.1.59

• 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

What's changed

• Expand Remote Control to more users

v2.1.56

What's changed

• VS Code: Fixed another cause of "command 'claude-vscode.editor.openLast' not found" crashes

v2.1.55

What's changed

• Fixed BashTool failing on Windows with EINVAL error

v2.1.53

What's changed

• 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.
• Fixed a security issue where HTTP hooks could interpolate arbitrary environment variables from header values. Env var interpolation now requires an explicit allowedEnvVars list in the hook configuration.
• 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
• HTTP hooks are now routed through the sandbox network proxy when sandboxing is enabled, enforcing the domain allowlist. HTTP hooks are not supported for SessionStart/Setup events.
• 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.

v2.1.50

What's changed

• 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

• 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

• 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

v2.1.49

What's changed

• Fixed Ctrl+C and ESC being silently ignored when background agents are running and the main thread is idle. Pressing twice within 3 seconds now kills all background agents.
• Fixed prompt suggestion cache regression that reduced cache hit rates.
• Fixed plugin enable and plugin disable to auto-detect the correct scope when --scope is not specified, instead of always defaulting to user scope
• Simple mode (CLAUDE_CODE_SIMPLE) now includes the file edit tool in addition to the Bash tool, allowing direct file editing in simple mode.
• Permission suggestions are now populated when safety checks trigger an ask response, enabling SDK consumers to display permission options
• 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.
• Fixed verbose mode not updating thinking block display when toggled via /config — memo comparators now correctly detect verbose changes
• Fixed unbounded WASM memory growth during long sessions by periodically resetting the tree-sitter parser
• Fixed potential rendering issues caused by stale yoga layout references
• Improved performance in non-interactive mode (-p) by skipping unnecessary API calls during startup
• Improved performance by caching authentication failures for HTTP and SSE MCP servers, avoiding repeated connection attempts to servers requiring auth
• Fixed unbounded memory growth during long-running sessions caused by Yoga WASM linear memory never shrinking
• SDK model info now includes supportsEffort, supportedEffortLevels, and supportsAdaptiveThinking fields so consumers can discover model capabilities.
• Added ConfigChange hook event that fires when configuration files change during a session, enabling enterprise security auditing and optional blocking of settings changes.
• 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

v2.1.47

What's changed

• Fixed FileWriteTool line counting to preserve intentional trailing blank lines instead of stripping them with trimEnd().
• 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.
• 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.
• 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)
• Improved memory usage in long-running sessions by releasing API stream buffers, agent context, and skill state after use
• Improved startup performance by deferring SessionStart hook execution, reducing time-to-interactive by ~500ms.
• Fixed an issue where bash tool output was silently discarded on Windows when using MSYS2 or Cygwin shells.
• 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.
• Improved memory usage by trimming agent task message history after tasks complete
• Improved memory usage during long agent sessions by eliminating O(n²) message accumulation in progress updates
• Fixed the bash permission classifier to validate that returned match descriptions correspond to actual input rules, preventing hallucinated descriptions from incorrectly granting permissions

• Windows: Fixed CWD tracking temp files never being cleaned up, causing them to accumulate indefinitely (anthropics/claude-code#17600)
• 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.
• 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.
• Simplified teammate navigation to use only Shift+Down (with wrapping) instead of both Shift+Up and Shift+Down.
• 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.
• 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.
• Fixed custom session titles set via /rename being lost after resuming a conversation (anthropics/claude-code#23610)
• Fixed collapsed read/search hint text overflowing on narrow terminals by truncating from the start.
• 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.
• Fixed built-in slash commands (/help, /model, /compact, etc.) being hidden from the autocomplete dropdown when many user skills are installed (anthropics/claude-code#22020)
• Fixed MCP servers not appearing in the MCP Management Dialog after deferred loading
• Fixed session name persisting in status bar after /clear command (anthropics/claude-code#26082)
• 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)
• Fixed /resume silently dropping sessions when the first message exceeds 16KB or uses array-format content (anthropics/claude-code#25721)
• Added chat:newline keybinding action for configurable multi-line input (anthropics/claude-code#26075)
• Added added_dirs to the statusline JSON workspace section, exposing directories added via /add-dir to external scripts (anthropics/claude-code#26096)
• Fixed claude doctor misclassifying mise and asdf-managed installations as native installs (anthropics/claude-code#26033)
• Fixed zsh heredoc failing with "read-only file system" error in sandboxed commands (anthropics/claude-code#25990)

• Fixed CJK wide characters causing misaligned timestamps and layout elements in the TUI (anthropics/claude-code#26084)
• Fixed custom agent model field in .claude/agents/*.md being ignored when spawning team teammates (anthropics/claude-code#26064)
• Fixed plan mode being lost after context compaction, causing the model to switch from planning to implementation mode (anthropics/claude-code#26061)
• Fixed alwaysThinkingEnabled: true in settings.json not enabling thinking mode on Bedrock and Vertex providers (anthropics/claude-code#26074)
• Fixed tool_decision OTel telemetry event not being emitted in headless/SDK mode (anthropics/claude-code#26059)
• Fixed session name being lost after context compaction — renamed sessions now preserve their custom title through compaction (anthropics/claude-code#26121)
• Increased initial session count in resume picker from 10 to 50 for faster session discovery (anthropics/claude-code#26123)
• Windows: fixed worktree session matching when drive letter casing differs (anthropics/claude-code#26123)
• Fixed /resume <session-id> failing to find sessions whose first message exceeds 16KB (anthropics/claude-code#25920)
• Fixed "Always allow" on multiline bash commands creating invalid permission patterns that corrupt settings (anthropics/claude-code#25909)
• 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)
