 # Changelog
 
+## 2.1.83
+
+- 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
+
+## 2.1.81
+
+- Added `--bare` flag for scripted `-p` calls — skips hooks, LSP, plugin sync, and skill directory walks; requires `ANTHROPIC_API_KEY` or an `apiKeyHelper` via `--settings` (OAuth and keychain auth disabled); auto-memory fully disabled
+- Added `--channels` permission relay — channel servers that declare the permission capability can forward tool approval prompts to your phone
+- Fixed multiple concurrent Claude Code sessions requiring repeated re-authentication when one session refreshes its OAuth token
+- Fixed voice mode silently swallowing retry failures and showing a misleading "check your network" message instead of the actual error
+- Fixed voice mode audio not recovering when the server silently drops the WebSocket connection
+- Fixed `CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS` not suppressing the structured-outputs beta header, causing 400 errors on proxy gateways forwarding to Vertex/Bedrock
+- Fixed `--channels` bypass for Team/Enterprise orgs with no other managed settings configured
+- Fixed a crash on Node.js 18
+- Fixed unnecessary permission prompts for Bash commands containing dashes in strings
+- Fixed plugin hooks blocking prompt submission when the plugin directory is deleted mid-session
+- Fixed a race condition where background agent task output could hang indefinitely when the task completed between polling intervals
+- Resuming a session that was in a worktree now switches back to that worktree
+- Fixed `/btw` not including pasted text when used during an active response
+- Fixed a race where fast Cmd+Tab followed by paste could beat the clipboard copy under tmux
+- Fixed terminal tab title not updating with an auto-generated session description
+- Fixed invisible hook attachments inflating the message count in transcript mode
+- Fixed Remote Control sessions showing a generic title instead of deriving from the first prompt
+- Fixed `/rename` not syncing the title for Remote Control sessions
+- Fixed Remote Control `/exit` not reliably archiving the session
+- Improved MCP read/search tool calls to collapse into a single "Queried {server}" line (expand with Ctrl+O)
+- Improved `!` bash mode discoverability — Claude now suggests it when you need to run an interactive command
+- Improved plugin freshness — ref-tracked plugins now re-clone on every load to pick up upstream changes
+- Improved Remote Control session titles to refresh after your third message
+- Updated MCP OAuth to support Client ID Metadata Document (CIMD / SEP-991) for servers without Dynamic Client Registration
+- Changed plan mode to hide the "clear context" option by default (restore with `"showClearContextOnPlanAccept": true`)
+- Disabled line-by-line response streaming on Windows (including WSL in Windows Terminal) due to rendering issues
+- [VSCode] Fixed Windows PATH inheritance for Bash tool when using Git Bash (regression in v2.1.78)
+
+## 2.1.80
+
+- Added `rate_limits` field to statusline scripts for displaying Claude.ai rate limit usage (5-hour and 7-day windows with `used_percentage` and `resets_at`)

+- Added CLI tool usage detection to plugin tips, in addition to file pattern matching
+- Added `effort` frontmatter support for skills and slash commands to override the model effort level when invoked
+- Added `--channels` (research preview) — allow MCP servers to push messages into your session

+- Fixed voice mode WebSocket failures caused by Cloudflare bot detection on non-browser TLS fingerprints
+- Fixed 400 errors when using fine-grained tool streaming through API proxies, Bedrock, or Vertex

+- Fixed `/sandbox` tab switching not responding to Tab or arrow keys
+- Improved responsiveness of `@` file autocomplete in large git repositories
+- Improved `/effort` to show what auto currently resolves to, matching the status bar indicator
+- Improved `/permissions` — Tab and arrow keys now switch tabs from within a list
+- Improved background tasks panel — left arrow now closes from the list view
+- Simplified plugin install tips to use a single `/plugin install` command instead of a two-step flow
+- Reduced memory usage on startup in large repositories (~80 MB saved on 250k-file repos)
+- Fixed managed settings (`enabledPlugins`, `permissions.defaultMode`, policy-set env vars) not being applied at startup when `remote-settings.json` was cached from a prior session
+
+## 2.1.79
+
+- Added `--console` flag to `claude auth login` for Anthropic Console (API billing) authentication

+- [VSCode] Session tabs now get AI-generated titles based on your first message
+- [VSCode] Fixed the thinking pill showing "Thinking" instead of "Thought for Ns" after a response completes
+- [VSCode] Fixed missing session diff button when opening sessions from the left sidebar
+
 ## 2.1.78
 
 - Added `StopFailure` hook event that fires when the turn ends due to an API error (rate limit, auth failure, etc.)
