Claude Code v1.0.22

# Claude Code v1.0.22 Changelog

Two new commands have been added for working with MCP (Model Context Protocol) resources:

• listMcpResources - Lists all available resources from configured MCP servers

  # List all resources from all MCP servers
  claude listMcpResources
  
  # List resources from a specific server
  claude listMcpResources --server myserver

• readMcpResource - Reads a specific resource from an MCP server

  # Read a resource by server name and URI
  claude readMcpResource --server myserver --uri my-resource-uri

• Added new permission mode: plan - Allows planning mode for complex operations
• Added defaultMode configuration option in permissions settings
• Added disableBypassPermissionsMode option to prevent bypassing permissions entirely
• Permission modes now available: acceptEdits, bypassPermissions, default, plan

Claude Code now follows the XDG Base Directory specification for better organization of files:

• State files: $XDG_STATE_HOME/claude/ (defaults to ~/.local/state/claude/)
• Cache files: $XDG_CACHE_HOME/claude/ (defaults to ~/.cache/claude/)
• Data files: $XDG_DATA_HOME/claude/ (defaults to ~/.local/share/claude/)
• Executables: ~/.local/bin/claude

The application will automatically migrate existing files from the old location (~/.claude/) to the new XDG-compliant locations on first run.

• Cell ID Support: Notebooks now support reading individual cells by their ID

  # Read a specific cell from a notebook
  claude notebook-read notebook.ipynb --cell-id cell-123

• Large cell outputs are now truncated with a helpful message indicating how to read the full output
• Improved cell metadata handling with proper cell IDs

• Enhanced history navigation with better state management
• History now properly tracks command length for improved user experience
• More robust handling of empty commands and history state

• Session message retrieval is now asynchronous for better performance
• Improved session file handling with async operations
• Better error handling for session loading and storage

• Fixed duplicate imports and removed unused stream imports
• Removed redundant Unicode sanitization variable declarations
• Cleaned up unused launcher script variables
• Fixed permission mode resolution to respect configuration settings

• Updated version to 1.0.22
• Improved code organization with better module separation
• Enhanced error messages for MCP operations
• Better type safety in permission mode handling
• Streamlined directory structure initialization

When upgrading to v1.0.22, Claude Code will automatically:

1. Check for existing files in ~/.claude/
2. Create new XDG-compliant directory structure
3. Migrate your existing data to the new locations
4. Create a migration marker to prevent repeated migrations

Your existing configurations, sessions, and data will be preserved during the migration.
