## Changes

### New Features

️ 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`

### Improvements

Performance Enhancements

### Technical Improvements

️ Code Architecture
