anthropics/claude-code v2.1.83

on GitHub

What's changed

• Added managed-settings.d/ drop-in directory alongside managed-settings.json, letting separate teams deploy independent policy fragments that merge alphabetically
• Added CwdChanged and FileChanged hook events for reactive environment management (e.g., direnv)
• Added sandbox.failIfUnavailable setting to exit with an error when sandbox is enabled but cannot start, instead of running unsandboxed
• Added disableDeepLinkRegistration setting to prevent claude-cli:// protocol handler registration
• Added CLAUDE_CODE_SUBPROCESS_ENV_SCRUB=1 to strip Anthropic and cloud provider credentials from subprocess environments (Bash tool, hooks, MCP stdio servers)
• Added transcript search — press / in transcript mode (Ctrl+O) to search, n/N to step through matches
• Added Ctrl+X Ctrl+E as an alias for opening the external editor (readline-native binding; Ctrl+G still works)
• Pasted images now insert an [Image #N] chip at the cursor so you can reference them positionally in your prompt
• Agents can now declare initialPrompt in frontmatter to auto-submit a first turn
• chat:killAgents and chat:fastMode are now rebindable via ~/.claude/keybindings.json
• Fixed mouse tracking escape sequences leaking to shell prompt after exit
• Fixed Claude Code hanging on exit on macOS
• Fixed screen flashing blank after being idle for a few seconds
• Fixed a hang when diffing very large files with few common lines — diffs now time out after 5 seconds and fall back gracefully
• Fixed a 1–8 second UI freeze on startup when voice input was enabled, caused by eagerly loading the native audio module
• Fixed a startup regression where Claude Code would wait ~3s for claude.ai MCP config fetch before proceeding
• Fixed --mcp-config CLI flag bypassing allowedMcpServers/deniedMcpServers managed policy enforcement
• Fixed claude.ai MCP connectors (Slack, Gmail, etc.) not being available in single-turn --print mode
• Fixed caffeinate process not properly terminating when Claude Code exits, preventing Mac from sleeping
• Fixed bash mode not activating when tab-accepting !-prefixed command suggestions
• Fixed stale slash command selection showing wrong highlighted command after navigating suggestions
• Fixed /config menu showing both the search cursor and list selection at the same time
• Fixed background subagents becoming invisible after context compaction, which could cause duplicate agents to be spawned
• Fixed background agent tasks staying stuck in "running" state when git or API calls hang during cleanup
• Fixed --channels showing "Channels are not currently available" on first launch after upgrade
• Fixed uninstalled plugin hooks continuing to fire until the next session
• Fixed queued commands flickering during streaming responses
• Fixed slash commands being sent to the model as text when submitted while a message is processing
• Fixed scrollback jumping when collapsed read/search groups finish after scrolling offscreen
• Fixed scrollback jumping to top when the model starts or stops thinking
• Fixed SDK session history loss on resume caused by hook progress/attachment messages forking the parentUuid chain
• Fixed copy-on-select not firing when you release the mouse outside the terminal window
• Fixed ghost characters appearing in height-constrained lists when items overflow
• Fixed Ctrl+B interfering with readline backward-char at an idle prompt — it now only fires when a foreground task can be backgrounded
• Fixed tool result files never being cleaned up, ignoring the cleanupPeriodDays setting
• Fixed space key being swallowed for up to 3 seconds after releasing voice hold-to-talk
• Fixed ALSA library errors corrupting the terminal UI when using voice mode on Linux without audio hardware (Docker, headless, WSL1)
• Fixed voice mode SoX detection on Termux/Android where spawning which is kernel-restricted
• Fixed Remote Control sessions showing as Idle in the web session list while actively running
• Fixed footer navigation selecting an invisible Remote Control pill in config-driven mode
• Fixed memory leak in remote sessions where tool use IDs accumulate indefinitely
• Improved Bedrock SDK cold-start latency by overlapping profile fetch with other boot work
• Improved --resume memory usage and startup latency on large sessions
• Improved plugin startup — commands, skills, and agents now load from disk cache without re-fetching
• Improved Remote Control session titles: AI-generated titles now appear within seconds of the first message
• Improved WebFetch to identify as Claude-User so site operators can recognize and allowlist Claude Code traffic via robots.txt
• Reduced WebFetch peak memory usage for large pages
• Reduced scrollback resets in long sessions from once per turn to once per ~50 messages
• Faster claude -p startup with unauthenticated HTTP/SSE MCP servers (~600ms saved)
• Bash ghost-text suggestions now include just-submitted commands immediately
• Increased non-streaming fallback token cap (21k → 64k) and timeout (120s → 300s local) so fallback requests are less likely to be truncated
• Interrupting a prompt before any response now automatically restores your input so you can edit and resubmit
• /status now works while Claude is responding, instead of being queued until the turn finishes
• Plugin MCP servers that duplicate an org-managed connector are now suppressed instead of running a second connection
• Linux: respect XDG_DATA_HOME when registering the claude-cli:// protocol handler
• Changed "stop all background agents" keybinding from Ctrl+F to Ctrl+X Ctrl+K to stop shadowing readline forward-char
• Deprecated TaskOutput tool in favor of using Read on the background task's output file path
• [VSCode] Spinner now turns red with "Not responding" when the backend hasn't responded for 60 seconds
• [VSCode] Fixed session history not loading correctly when reopening a session via URL or after restart
