 - Improved the list of your attached files: every file now appears under the folder it came from, and each folder is named only once, no matter in which order you attached your files.
 - Changed how provider trust and provider confidence work together. Marking a provider as trustworthy in a configuration no longer also satisfies a required confidence level: one says who runs the provider, the other how confidential it is. Organizations raise a provider's level in their own confidence scheme instead. This applies beyond local data sources, for example, when a model reads a page from your intranet.
 - Fixed the abilities AI Studio assumed for many models. We checked the families against their documentation: some models gained image input, reasoning, or tool calling, others lost an ability they never had.
+- Fixed the Document Analysis assistant becoming unresponsive when choosing an LLM provider.
 - Fixed model names that a provider writes in its own way not being recognized at all, such as the colon Ollama puts before the variant. Those models were treated as plain text models and lost every other ability.
 - Fixed a model resold under a plain name not getting the abilities it really has.
 - Fixed image and video generation models showing up among the chat models.
