v2.1.105
Claude CodeSummary
This release introduces significant enhancements to tool capabilities, including adding a `path` parameter to `EnterWorktree` and enabling background monitor support for plugins. Numerous fixes address issues related to UI rendering, queued message handling, and network error reporting, alongside several quality-of-life improvements for configuration and debugging.
New Features
- Added the `path` parameter to the `EnterWorktree` tool, allowing users to switch into an existing worktree of the current repository.
- Added background monitor support for plugins via a top-level `monitors` manifest key that automatically arms at session start or on skill invoke.
- Added PreCompact hook support, enabling hooks to block compaction by exiting with code 2 or returning `{"decision":"block"}`.
- /proactive is now an alias for /loop.
Bug Fixes
- Fixed images attached to queued messages (sent while Claude is working) being dropped.
- Fixed the screen going blank when the prompt input wraps to a second line in long conversations.
- Fixed leading whitespace being copied when selecting multi-line assistant responses in fullscreen mode.
- Fixed leading whitespace being trimmed from assistant messages, which broke ASCII art and indented diagrams.
- Fixed garbled bash output when commands print clickable file links (e.g. Python `rich`/`loguru` logging).
- Fixed alt+enter not inserting a newline in terminals using ESC-prefix alt encoding, and Ctrl+J not inserting a newline (regression in 2.1.100).
- Fixed duplicate "Creating worktree" text in EnterWorktree/ExitWorktree tool display.
- Fixed queued user prompts disappearing from focus mode.
- Fixed one-shot scheduled tasks re-firing repeatedly when the file watcher missed the post-fire cleanup.
- Fixed inbound channel notifications being silently dropped after the first message for Team/Enterprise users.
- Fixed marketplace plugins with `package.json` and lockfile not having dependencies installed automatically after install/update.
- Fixed marketplace auto-update leaving the official marketplace in a broken state when a plugin process holds files open during the update.
- Fixed "Resume this session with..." hint not printing on exit after `/resume`, `--worktree`, or `/branch`.
- Fixed feedback survey shortcut keys firing when typed at the end of a longer prompt.
- Fixed stdio MCP server emitting malformed (non-JSON) output hanging the session instead of failing fast with "Connection closed".
- Fixed MCP tools missing on the first turn of headless/remote-trigger sessions when MCP servers connect asynchronously.
- Fixed `/model` picker on AWS Bedrock in non-US regions persisting invalid `us.*` model IDs to `settings.json` when inference profile discovery is still in-flight.
- Fixed 429 rate-limit errors showing a raw JSON dump instead of a clean message for API-key, Bedrock, and Vertex users.
- Fixed crash on resume when session contains malformed text blocks.
- Fixed `/help` dropping the tab bar, Shortcuts heading, and footer at short terminal heights.
- Fixed malformed keybinding entry values in `keybindings.json` being silently loaded instead of rejected with a clear error.
- Fixed `CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC` in one project's settings permanently disabling usage metrics for all projects on the machine.
- Fixed washed-out 16-color palette when using Ghostty, Kitty, Alacritty, WezTerm, foot, rio, or Contour over SSH/mosh.
- Fixed Bash tool suggesting `acceptEdits` permission mode when exiting plan mode would downgrade from a higher permission level.
Improvements
- Improved handling of stalled API streams: streams now abort after 5 minutes of no data and retry non-streaming instead of hanging indefinitely.
- Improved network error messages: connection errors now show a retry message immediately instead of a silent spinner.
- Improved file write display: long single-line writes (e.g. minified JSON) are now truncated in the UI instead of paginating across many screens.
- Improved `/doctor` layout with status icons; users can now press `f` to have Claude fix reported issues.
- Improved `/config` labels and descriptions for clarity.
- Improved skill description handling: raised the listing cap from 250 to 1,536 characters and added a startup warning when descriptions are truncated.
- Improved `WebFetch` to strip `<style>` and `<script>` contents from fetched pages so CSS-heavy pages no longer exhaust the content budget before reaching actual text.
- Improved stale agent worktree cleanup to remove worktrees whose PR was squash-merged instead of keeping them indefinitely.
- Improved MCP large-output truncation prompt to give format-specific recipes (e.g. `jq` for JSON, computed Read chunk sizes for text).
