  • Objective-aware frontiers in GEPA for quality, privacy, or cost metrics

Improvements

  • Substantially strengthened sandbox isolation and integrity checks
  • Interpreter stability and optimization
  • MCP SDK v2 compatibility
  • Adapter correctness improvements

Bug Fixes

  • Multiple interpreter execution integrity fixes
  • Sandbox startup configuration overrides removed
