Claude Code v1.0.68

Based on my analysis of the diff file for version 1.0.68, here is the detailed changelog:

# Claude Code v1.0.68 Changelog

A powerful new --teleport feature allows you to resume Claude Code sessions from other machines or continue someone else's shared session.

Usage:

# Resume by session ID
claude --teleport abc123def456

# Resume from a URL
claude --teleport https://claude.ai/chat/abc123def456

Features:

• Automatically fetches conversation history from remote sessions
• Switches to the appropriate git branch if needed
• Offers to stash uncommitted changes before switching branches
• Supports custom headers via TELEPORT_HEADERS environment variable
• Validates authentication status before proceeding

Environment Variables:

• TELEPORT_RESUME_URL: Override the default URL for session resumption
• TELEPORT_HEADERS: Pass custom headers as JSON (e.g., export TELEPORT_HEADERS='{"Authorization": "Bearer token"}')

Configure how Claude Code communicates with you by selecting from different output modes.

Features:

• Support for custom output modes stored in .claude/output-modes/ directories
• Both user-level and project-level output mode configurations
• Interactive selection UI with up to 10 visible options (increased from 3)
• Dynamic loading with "Loading output modes..." indicator
• Each mode includes a description to help you choose

New global control over Claude Code's hook system for better troubleshooting and control.

New Capability:

• Disable all hooks globally without deleting your configuration
• Clear UI indicator when hooks are disabled showing:

• The expanded shell command whitelist improves productivity for common system tasks while maintaining security
