Key Points

  • v0.20.6 adds a documentation guide for integrating the Hermes agent, making setup steps more accessible for developers.
  • The app UI now re-validates selected image attachments whenever the chosen model changes, reducing mismatches between attachments and model expectations.
  • Model parsers were updated to fix missing parallel tool call indices, improving reliability when handling concurrent tool invocations.
  • The Gemma4 model renderer was updated to align with a new Jinja template, and parsing strictness around whitespace before bare keys was relaxed to prevent avoidable failures.
