 # v26.1.2, build 232 (2026-01-xx xx:xx UTC)
 - Added the option to hide specific assistants by configuration plugins. This is useful for enterprise environments in organizations.
+- Improved error handling for model loading in provider dialogs (LLMs, embeddings, transcriptions).
 - Fixed a logging bug that prevented log events from being recorded in some cases.
 - Fixed a bug that allowed adding a provider without selecting a model.
 - Fixed a bug with local transcription providers by handling errors correctly when the local provider is unavailable.
