This page details all confirmed bug fixes released in FastGPT 4.12.2, targeting stability, UI rendering, and functional integrity across core platform workflows and user-facing features. All fixes address gaps reported in prior 4.12.x platform releases.

Standalone Chat Page Improvements

The standalone chat interface received three targeted fixes:

  1. Resolved all reported UI rendering inconsistencies on the standalone chat page
  2. Fixed a bug where plugin interactions failed to render correctly on the standalone chat view
  3. Corrected the default URL configuration for deployments using sub-routes, eliminating broken navigation paths for standalone chat instances.
