Version 0.2.65

️ Sandbox Mode for Bash Commands

• New sandbox parameter for the Bash tool that enables sandboxed command execution
• Commands run in sandbox mode are executed with restricted permissions - they can read files but cannot write to the filesystem or access the network
• Key benefit: Commands run with sandbox=true execute immediately without requiring user permission, providing a smoother user experience
• Usage example: claude --sandbox ls -la (read-only operations run immediately)

Enhanced Paste Detection

• Added support for bracketed paste mode in the terminal
• When pasting multi-line content, Claude Code now properly detects and handles pasted input
• Prevents accidental command execution when pasting code blocks

Improved Permission Rules System

• Enhanced permission management UI with better organization
• New "Add permission rule" dialog for creating custom tool permissions
• Permission rules now support more granular control with specifiers (e.g., Bash(ls:*))
• Permission rules can be saved to local project settings or shared project settings

Release Notes Integration

• New release-notes command to view changelog directly in the CLI
• Automatically fetches and displays recent version changes
• Falls back to offline changelog if network is unavailable
• Usage: claude release-notes

Performance Enhancements

• Better handling of Unicode text in wrapped terminal output
• Improved text wrapping algorithm that correctly handles normalized Unicode characters
• More efficient handling of large output with JSON formatting support

API Retry Logic

• Enhanced retry mechanism with optional error display control
• New showErrors parameter in retry configuration
• Better handling of API rate limits and context overflow errors

User Experience

• Added desktop notifications for idle sessions (triggers after 30 seconds of inactivity)
• New tipsHistory setting to track displayed tips
• Improved handling of API errors with clearer messaging

️ Code Architecture

• Introduced tree-kill library for better process management
• New eG0 class for managing macOS sandbox profiles
• Enhanced signal handling with proper cleanup on process termination
• Improved abort controller management for better command cancellation

Tool Updates

• Bash tool description now dynamically includes sandbox mode instructions
• Better documentation of which commands require write access vs read-only
• Comprehensive lists of commands that should use sandbox mode

• Fixed Unicode normalization issues in text wrapping
• Improved handling of incomplete escape sequences in terminal input
• Better cleanup of temporary sandbox profiles
• Fixed race conditions in process termination

• Added sandbox parameter to Bash tool schema
• New hy() function to check sandbox availability
• Jr() function to wrap commands with sandbox execution
• Enhanced process spawning with detached: true option for better process group management
