Version 2.1.6

Claude Code now automatically injects authentication tokens when cloning HTTPS repositories, supporting GitHub, GitLab, and Bitbucket.

Usage: Set the appropriate environment variable and clone private repositories seamlessly:

export GITHUB_TOKEN=your_token
# Or: GH_TOKEN, GITLAB_TOKEN, GL_TOKEN, BITBUCKET_TOKEN

• Automatically detects authentication failures and retries with token injection
• Supports GITHUB_TOKEN/GH_TOKEN for github.com
• Supports GITLAB_TOKEN/GL_TOKEN for gitlab.com and GitLab self-hosted instances
• Supports BITBUCKET_TOKEN for bitbucket.org
• Tokens in error messages are automatically redacted for security
• Preserves SSH_AUTH_SOCK for SSH key agent forwarding

New /keybindings command to open or create a keybindings configuration file for customizing keyboard shortcuts.

/keybindings

• Opens or creates ~/.config/claude-code/keybindings.json
• Template includes syntax documentation for modifiers (ctrl, alt, shift, meta)
• Supports chord shortcuts like "ctrl+k ctrl+s"
• File is automatically reloaded when saved
• Documents reserved keys (ctrl+c, ctrl+d) and terminal conflicts (ctrl+b, ctrl+a, ctrl+z)
• Feature is currently in preview and may need to be enabled

The /stats command now supports filtering by date range with a keyboard shortcut to cycle through options.

Usage: Press r while viewing stats to cycle through:

• All time (default)
• Last 7 days
• Last 30 days

• Displays loading indicator when fetching filtered stats
• Shows "r to cycle dates" in the help text
• Caches fetched date ranges for faster switching

• Supports numpad Enter key

The "add directory to workspace" dialog now includes path autocomplete functionality with tab completion.

• Press Tab to autocomplete the current directory suggestion
• Shows directory suggestions as you type
• Navigate suggestions with up/down arrows or ctrl+p/ctrl+n

The /version command now shows both stable and latest versions from npm dist-tags and GCS.

• Fetches version info from npm with --prefer-online flag
• Falls back to GCS storage for version information
• Displays "Stable version" and "Latest version" separately

zD7() at line 495798 (version display, contains "Stable version", "Latest version")

Added structured logging for MCP (Model Context Protocol) server errors and debug messages.

• New logMCPError() and logMCPDebug() functions for server-specific logging
• MCP logs stored separately per server in mcp-logs-{serverName} directories
• Error log sink initialization with buffering for early errors before sink is ready

Lq9() at line 536969 (error log sink initialization, contains logMCPError, logMCPDebug)

The shell command explanation system has been refactored from structured outputs to a tool-based approach.

• Now uses explain_command tool with explicit JSON schema
• Cleaner separation between explanation, reasoning, and risk assessment
• Simplified system prompt: "Analyze shell commands and explain what they do, why you're running them, and potential risks."

zE5 at line 2256 (tool definition, contains "explain_command")

When exiting plan mode, Claude can now request prompt-based bash permissions that will be pre-approved for the session.

• New allowedPrompts parameter accepts semantic descriptions of actions
• Example: {"tool": "Bash", "prompt": "run tests"} matches npm test, pytest, etc.
• Permissions are session-scoped and cleared when the session ends
• Guidelines encourage narrow, security-conscious permission scoping

The /stats comparison feature now includes more books for token usage comparison.

Details: Added 10 new books including "The Little Prince", "A Christmas Carol", "Fahrenheit 451", "Slaughterhouse-Five", "The Catcher in the Rye", "Dune", "Moby-Dick", "Crime and Punishment", "A Game of Thrones", "The Count of Monte Cristo", and "Les Misérables".

Added more time-based comparisons for session duration statistics.

Details: Added comparisons including "listening to Abbey Road", "a yoga class", "a World Cup soccer match", "watching Titanic", and "a full night of sleep".

• Fixed path truncation for long file paths in autocomplete suggestions with smart ellipsis placement (ItQ() at line 139331, preserves filename visibility)

The cache warming feature has been completely removed.

• Removed Dr5() cache warming configuration function
• Removed In2() cache warming hook
• Removed tengu_cache_warming_request telemetry
• Removed agent warmup functionality (iU9, yS0 functions)

A quick side question feature allowing users to ask tangential questions without interrupting the main conversation flow.

Stubbed - command infrastructure exists but isEnabled returns false.

• Registered as /btw command
• Description: "Ask a quick side question without interrupting the main conversation"
• Side question infrastructure (API calls, response handling) already exists from previous versions
• Parser function returns { isBtw: !1 } (always false)
