Executive Summary

• Code Review is now a managed service (research preview for Teams/Enterprise) that automatically reviews PRs using a fleet of specialized agents, posting inline comments with severity levels
• CLAUDE.local.md removed: The local project-specific CLAUDE.md file format is no longer supported; use home-directory imports instead for personal preferences
• Claude Code 2.1.72: Major release with ExitWorktree tool, effort level simplification (low/medium/high), restored model parameter on the Agent tool, and a fix that reduces prompt cache costs up to 12x in SDK query() calls
• /review command deprecated: The built-in /review slash command is deprecated; users should install the code-review plugin from the marketplace instead
• Settings doc updated with many new tools now available to Claude: Cron tools for scheduled tasks, Worktree entry/exit tools, TodoWrite, ToolSearch, and more

New Claude Code versions

2.1.72

New features

• Added w key in /copy to write the focused selection directly to a file, bypassing the clipboard (useful over SSH)
• Added optional description argument to /plan (e.g., /plan fix the auth bug) that enters plan mode and immediately starts
• Added ExitWorktree tool to leave an EnterWorktree session
• Added CLAUDE_CODE_DISABLE_CRON environment variable to immediately stop scheduled cron jobs mid-session
• Added lsof, pgrep, tput, ss, fd, and fdfind to the bash auto-approval allowlist, reducing permission prompts for common read-only operations
• Restored the model parameter on the Agent tool for per-invocation model overrides
• Added support for marketplace git URLs without .git suffix (Azure DevOps, AWS CodeCommit)
• VSCode: Added effort level indicator on the input border
• VSCode: Added vscode://anthropic.claude-code/open URI handler to open a new Claude Code tab programmatically, with optional prompt and session query parameters

Existing feature improvements

• Simplified effort levels to low/medium/high (removed max) with new symbols (○ ◐ ●) and a brief notification instead of a persistent icon; use /effort auto to reset to default
• Improved /config — Escape now cancels changes, Enter saves and closes, Space toggles settings
• Improved up-arrow history to show current session's messages first when running multiple concurrent sessions
• Improved voice input transcription accuracy for repo names and common dev terms (regex, OAuth, JSON)
• Improved bash command parsing by switching to a native module — faster initialization and no memory leak
• Reduced bundle size by ~510 KB
• Changed CLAUDE.md HTML comments (<!-- ... -->) to be hidden from Claude when auto-injected (comments remain visible when read with the Read tool)
• Fixed tool search to activate even with ANTHROPIC_BASE_URL as long as ENABLE_TOOL_SEARCH is set

Major bug fixes

• Fixed prompt cache invalidation in SDK query() calls, reducing input token costs up to 12x
• Fixed slow exits when background tasks or hooks were slow to respond
• Fixed --continue not resuming from the most recent point after --compact
• Fixed skill hooks firing twice per event when a hooks-enabled skill is invoked by the model
• Fixed several voice mode issues: occasional input lag, false "No speech detected" errors, and stale transcripts re-filling the prompt after submission
• Fixed /clear killing background agent/bash tasks — only foreground tasks are now cleared
• Fixed worktree isolation issues: Task tool resume not restoring cwd, and background task notifications missing worktreePath and worktreeBranch
• Fixed parallel tool calls where a failed Read/WebFetch/Glob would cancel its siblings — only Bash errors now cascade
• Fixed double Ctrl+C not exiting when background agents or tasks are running
• Fixed several hooks issues including transcript_path pointing to the wrong directory and async hooks not receiving stdin
• Fixed several permission rule matching issues including wildcard rules not matching commands with heredocs and deny rules not applying to all command forms
• Fixed several plugin issues including installation failing on Windows and marketplace blocking user-scope installs

Claude Code changes

New Documents

Code Review [Source]

New document covering the Code Review managed service (research preview for Teams and Enterprise). A fleet of specialized agents automatically reviews GitHub pull requests, posting inline comments with severity levels (Normal/Nit/Pre-existing). Setup is done once by an admin and runs automatically on PR open/update. Reviews can be customized via CLAUDE.md and a new REVIEW.md file. Reviews average $15–25 and activity can be monitored via the analytics dashboard.
