Claude Code v0.2.37

/release-notes Command

A new slash command that displays release notes for all versions of Claude Code.

Usage:

/release-notes

This command shows the complete release history with version numbers and their corresponding changes. The release notes are now always available and enabled by default (isEnabled: !0), replacing the previous version-specific implementation.

Enhanced config add/remove Commands

The claude config add and claude config remove commands now support adding or removing multiple values at once.

New capabilities:

• Add multiple values to array-based configuration options in a single command
• Values can be separated by commas or spaces
• The command now tracks the count of items being added/removed
• Items are automatically deduplicated using Set operations
• Lists are sorted alphabetically after modifications

Examples:

# Add multiple tools to allowed tools
claude config add allowedTools Read,Write,Edit

# Remove multiple patterns from ignore patterns  
claude config remove ignorePatterns "*.log" "*.tmp" "build/"

# Works with both global and project configs
claude config add --global mcpServers server1,server2,server3

Kitty Terminal Notification Support

Added native notification support for Kitty terminal emulator using the OSC 99 protocol.

How it works:

• When using Kitty terminal, Claude Code can now send desktop notifications
• Notifications include both title and body text
• Automatically detected when preferredNotifChannel is set to "auto"
• Can be explicitly enabled with claude config set preferredNotifChannel kitty
