2 | 2 |
|
| 3 | +## 2.1.212 |
| 4 | + |
| 5 | +- `/fork` now copies your conversation into a new background session (its own row in `claude agents`) while you keep working; the in-session subagent it used to launch is now `/subtask` |
| 6 | +- Added `claude auto-mode reset` to restore the default auto-mode configuration, with a confirmation prompt (pass `--yes` to skip) |
| 7 | +- Added a session-wide limit on WebSearch tool calls (default 200, tunable via `CLAUDE_CODE_MAX_WEB_SEARCHES_PER_SESSION`) to stop runaway search loops |
| 8 | +- Added a per-session cap on subagent spawns (default 200, override with `CLAUDE_CODE_MAX_SUBAGENTS_PER_SESSION`) to stop runaway delegation loops; `/clear` resets the budget |
| 9 | +- MCP tool calls running longer than 2 minutes now move to the background automatically so the session stays usable; configure the threshold or disable with `CLAUDE_CODE_MCP_AUTO_BACKGROUND_MS` |
| 10 | +- Typing `/resume` in the agent view now opens a picker of past sessions — including sessions deleted from the list — and resumes your pick as a background session |
| 11 | +- Fixed plan mode auto-running file-modifying Bash commands (e.g. `touch`, `rm`) without a permission prompt or SDK `canUseTool` callback |
| 12 | +- Fixed worktree creation following a repository-committed symlink at `.claude/worktrees`, which could create files outside the repository |
| 13 | +- Fixed a `continue:false` hook's halt being dropped when the tool fails or completes mid-stream, and hook infrastructure errors being misreported as user rejections |
| 14 | +- Fixed SIGTERM during a running Bash tool orphaning the command's process tree in print/SDK mode; the CLI now aborts the turn, kills the tree, and exits 143 |
| 15 | +- Fixed `/background` and `claude --bg` failing with "EUNKNOWN: unknown error, uv_spawn" on Windows when Group Policy blocks PowerShell 5.1; the daemon now prefers PowerShell 7 |
| 16 | +- Fixed shell mode (`!`) not executing commands containing file paths while the path autocomplete popup was open |
| 17 | +- Fixed auto-mode denial notifications rendering broken characters when a long denial reason was truncated mid-emoji |
| 18 | +- Fixed Ctrl+J not inserting a newline in the agent view dispatch input on terminals with extended key reporting, and surfaced the newline shortcut in the `?` help overlay |
| 19 | +- Fixed `/ultrareview` rejecting PR references like `#123`, `PR 123`, and pasted PR URLs; error hints now name the command you actually typed |
| 20 | +- Fixed `/ultrareview <branch>` not fetching the branch from origin when it exists remotely; it now suggests the closest branch name on typos |
| 21 | +- Fixed `/ultrareview` skipping the billing confirmation in a new conversation after `/clear` |
| 22 | +- Fixed `/ultrareview`'s "not a git repository" error on Claude Desktop now suggesting the project's repository folder instead of terminal commands |
| 23 | +- Fixed hosted (host-managed) sessions failing at startup when repository settings configured mTLS certs, extra CA bundles, or OAuth scopes; these transport settings are now ignored with a warning |
| 24 | +- Fixed a spurious "File has not been read yet" error when editing a file that had been read with offset/limit before resuming a session |
| 25 | +- Fixed `ExitWorktree` failing with "no active EnterWorktree session" after resuming a session with `--continue`/`--resume` in print/SDK mode |
| 26 | +- Fixed the workflow agent grid staying empty for Remote Control clients that join a session mid-run |
| 27 | +- Fixed streaming-mode control requests being marked complete before their handler finished, which could lose the request on session restart |
| 28 | +- Fixed background sessions created with `/fork` losing their live-parent protection after a state write failure |
| 29 | +- Fixed reopening a stopped background session from the agent view failing silently — it now resumes the session, or shows why it can't and lets you force a restart |
| 30 | +- Fixed agent teams: a stopping teammate could send the leader duplicate idle notifications when team initialization re-ran within a session |
| 31 | +- Fixed the plan-approval dialog footer splitting "ctrl+g to edit in <editor>" apart when the file path is long |
| 32 | +- Fixed the welcome banner keeping its old panel widths after a combined width+height terminal resize in fullscreen mode |
| 33 | +- Fixed diff previews losing their line numbers and +/- markers in narrow layouts |
| 34 | +- Fixed @-mentions attaching nothing after a partial file read, plugin uninstall targeting the wrong marketplace, and false "Command timed out" on exit code 143 |
| 35 | +- Fixed OpenTelemetry HTTP exports being rejected with 411/400 by Azure Monitor and other endpoints that don't accept chunked transfer encoding |
| 36 | +- Fixed OTLP event log records missing `trace_id`/`span_id` when `TRACEPARENT` is set in SDK/headless mode |
| 37 | +- Fixed conversations with many images incorrectly failing with "Request too large" errors, and improved the error message to explain the actual cause |
| 38 | +- Fixed web search and web fetch returning "API Error" text as search results or page content when the API was overloaded |
| 39 | +- Improved web search and web fetch reliability by retrying 529 errors and rate-limited requests with bounded backoff |
| 40 | +- Improved prompt caching: the mid-conversation system block now works behind LLM gateways and custom base URLs (Bedrock, Vertex, 1P) |
| 41 | +- Improved background agent attach: cold-attaching now instantly shows the formatted transcript while the session boots, instead of a blank wait |
| 42 | +- Reduced token usage in inter-agent messaging: `SendMessage` bodies are no longer duplicated into replayed history and tool results |
| 43 | +- Changed `/fork` to name the copy after your prompt when the session has no title, so the row is recognizable in the agent view |
| 44 | +- Changed bare `/btw` to reopen the side-question panel on your most recent exchange so you can browse earlier answers |
| 45 | +- Changed the `←` footer hint to pulse `N done` for a moment when a background agent finishes while nothing needs your input |
| 46 | +- Deprecated the Task tool's `mode` parameter (now ignored); subagents inherit the parent session's permission mode by default |
| 47 | +- Changed Enterprise `forceLoginMethod` to be enforced for VS Code extension, SDK, `setup-token`, and `install-github-app` logins, not just the terminal |
| 48 | +- Changed session transcripts to record the reasoning effort level on each assistant message |
| 49 | +- Changed headless/SDK sessions to apply a `set_model` control request mid-turn; the next model round-trip uses the new model instead of waiting for the next turn |
| 50 | +- Changed agent view / `claude agents --json`: sessions waiting on a sandbox, MCP-input, or managed-settings prompt now show as "Needs input" instead of "Working" |
| 51 | +- Updated the auth status panel title from "Cloud authentication" to "Authentication" |
| 52 | +- Corrected an earlier release note (2.1.200): tmux through the 3.6 series lacks synchronized output; newer tmux with support is detected automatically |
| 53 | + |
3 | 54 | ## 2.1.211 |
4 | 55 |
|
5 | 56 | - Added `--forward-subagent-text` flag and `CLAUDE_CODE_FORWARD_SUBAGENT_TEXT` environment variable to include subagent text and thinking in stream-json output |
