Claude Code v2.1.116: 67% Faster Resume on Large Sessions, MCP Startup Optimization, Sandbox Security Hardening
Releasebot·high signal
Released April 21, v2.1.116 delivers a 67% improvement in /resume speed for sessions over 40MB — a meaningful quality-of-life gain for long-running agent sessions. MCP startup is now faster when multiple stdio servers are configured, and inline thinking progress indicators replace separate hint rows. Security-wise, sandbox auto-allow now properly enforces dangerous-path checks for critical directories, closing a permission bypass.
