[Release] anthropics/claude-code v2.1.116: v2.1.116

Claude Code v2.1.116 delivers significant performance improvements, enhanced user experience features, and critical bug fixes. Key updates include 67% faster session resumption for large files, improved MCP startup performance, smoother terminal scrolling, and a more informative thinking spinner. The release also strengthens security measures, fixes terminal rendering issues across multiple platforms, and resolves API stability problems.

Key Points

• •Session resume performance improved up to 67% for 40MB+ sessions with better handling of dead-fork entries
• •MCP startup accelerated by deferring `resources/templates/list` to first @-mention when multiple stdio servers configured
• •Terminal scrolling smoothness enhanced across VS Code, Cursor, and Windsurf with configurable scroll sensitivity via `/terminal-setup`
• •Thinking spinner now displays inline progress indicators ('still thinking', 'thinking more', 'almost done thinking') instead of separate hint row
• •Config search expanded to match option values, enabling searches like 'vim' to find Editor mode settings
• •Doctor command now accessible during Claude responses without waiting for turn completion
• •Plugin dependency auto-installation from previously added marketplaces for `/reload-plugins` and background updates
• •Bash tool provides GitHub API rate limit hints to enable agent backoff strategies instead of retries
• •Security hardened: sandbox auto-allow no longer bypasses dangerous-path checks for critical system directories (/, $HOME)
• •Fixed critical terminal issues: Indic script rendering, keyboard protocol compatibility (Kitty, iTerm2, Ghostty), and scrollback duplication
