[Release] anthropics/claude-code v2.1.70: v2.1.70

Claude Code v2.1.70 release fixes multiple critical issues including API 400 errors with third-party gateways, model response problems after ToolSearch, clipboard corruption on Windows, and voice mode failures. The update also improves performance with 74% fewer prompt re-renders, adds VS Code session management in the activity bar, and introduces native MCP server management through the `/mcp` command.

Key Points

• •Fixed API compatibility issues with third-party gateways and custom model identifiers by disabling unsupported tool_reference blocks and effort parameters

• •Improved voice mode stability on Windows native binary and fixed push-to-talk activation on session start
• •Enhanced MCP server management with native dialog interface accessible via /mcp command for enabling/disabling servers and OAuth authentication
• •Optimized performance by reducing prompt input re-renders by ~74% and cutting Remote Control polling server load by ~300×
• •Added VS Code activity bar integration showing all Claude Code sessions as full editors with spark icon
• •Implemented full markdown document view for plans with comment feedback capability in VS Code
• •Fixed plugin marketplace synchronization and legacy model notification issues
