Claude Code v2.1.212

What's changed

• /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
• Added claude auto-mode reset to restore the default auto-mode configuration, with a confirmation prompt (pass --yes to skip)
• 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
• 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
• 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
• 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
• Fixed plan mode auto-running file-modifying Bash commands (e.g. touch, rm) without a permission prompt or SDK canUseTool callback
• Fixed worktree creation following a repository-committed symlink at .claude/worktrees, which could create files outside the repository
• 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
• 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
• 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
• Fixed shell mode (!) not executing commands containing file paths while the path autocomplete popup was open
• Fixed auto-mode denial notifications rendering broken characters when a long denial reason was truncated mid-emoji
• 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
• Fixed /ultrareview rejecting PR references like #123, PR 123, and pasted PR URLs; error hints now name the command you actually typed
• Fixed /ultrareview <branch> not fetching the branch from origin when it exists remotely; it now suggests the closest branch name on typos
• Fixed /ultrareview skipping the billing confirmation in a new conversation after /clear
• Fixed /ultrareview's "not a git repository" error on Claude Desktop now suggesting the project's repository folder instead of terminal commands
• 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
• 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
• Fixed ExitWorktree failing with "no active EnterWorktree session" after resuming a session with --continue/--resume in print/SDK mode
• Fixed the workflow agent grid staying empty for Remote Control clients that join a session mid-run
• Fixed streaming-mode control requests being marked complete before their handler finished, which could lose the request on session restart
• Fixed background sessions created with /fork losing their live-parent protection after a state write failure
• 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
• Fixed agent teams: a stopping teammate could send the leader duplicate idle notifications when team initialization re-ran within a session
• Fixed the plan-approval dialog footer splitting "ctrl+g to edit in <editor>" apart when the file path is long
• Fixed the welcome bann
