Version 15.7.0 introduces user feedback annotations, session tagging improvements, and updates the UI toast behavior. This release also removes the deprecated v1 agent /chat route.

✨ New Features

  • Prevented format-string injection vulnerability in the f-string template formatter.
  • Ensured playground validation errors are surfaced correctly.
