Claude Code v2.1.72 Brings Major Efficiency and Usability Improvements

Claude Code v2.1.72 has been released. This update includes numerous improvements and bug fixes aimed at enhancing developer productivity.

Key New Features and Improvements

Simplified Effort Levels

Effort levels have been simplified to three tiers: low, medium, and high. The “max” option has been removed. New symbols (○ ◐ ●) are used for display, with brief notifications instead of persistent icons. Use /effort auto to reset to default.

Enhanced /copy Command

The /copy command now supports the w key, which writes the selected content directly to a file, bypassing the clipboard. Particularly useful over SSH connections.

Improved /plan Command

The /plan command now accepts an optional description argument. For example: /plan fix the auth bug will enter plan mode and immediately start planning.

New ExitWorktree Tool

The ExitWorktree tool has been added, allowing users to cleanly exit an EnterWorktree session.

Expanded Bash Auto-Approval List

The following commands have been added to the bash auto-approval list, reducing permission prompts for common read-only operations:

• lsof
• pgrep
• tput
• ss
• fd
• fdfind

Improved /config Command

The /config command has been enhanced with new keyboard shortcuts:

• Escape: Cancel changes
• Enter: Save and close
• Space: Toggle settings

Performance Improvements

• Bash parser switched to native module: faster initialization and no memory leak
• Bundle size reduced by approximately 510KB
• Improved CPU utilization in long sessions
• Better responsiveness when exiting

Voice Input Improvements

Voice input transcription accuracy has been improved for repository names and common dev terms (regex, OAuth, JSON).

Bug Fixes

• Tool search now activates even with ANTHROPIC_BASE_URL set, as long as ENABLE_TOOL_SEARCH is set
• Up-arrow history now shows current session messages first when running multiple concurrent sessions
• —continue now resumes from the most recent point after —compact
• /clear no longer kills background tasks
• Fixed sandbox permission issues
• Fixed skill hooks firing twice per event
• Fixed worktree isolation issues
• Fixed feedback survey appearing too frequently in long sessions

Environment Variables

• CLAUDE_CODE_DISABLE_CRON: Immediately stop scheduled cron jobs mid-session
