v1.3

Chat Compaction & WebUI Extension Points

March 27, 2026

v1.3 improves long-conversation handling and plugin extensibility. It introduces a dedicated chat compaction plugin and adds a native page-head extension point so plugins can load scripts and styles without brittle DOM workarounds.

✨ New Features

  • Added built-in Chat Compaction plugin to compress long chat histories and reduce context pressure.
  • Added page-head WebUI extension point so plugins can inject script and stylesheet tags in a clean way.
  • Included plugin thumbnail support for newly introduced built-in plugins.

⚡ Improvements

  • Simplified plugin index fetch internals by removing the server-side force parameter.
  • Updated the a0-development skill.
  • Improved release workflow fallback behavior and OpenRouter environment variable handling.
