 - Improved the app icon. The previous one was generated by an image model; the new one was created based on it and keeps the familiar green landscape with the chat bubble. Because it is now a vector drawing, it stays sharp everywhere it appears: in your taskbar or dock, in the window list, and on the start screen while AI Studio is loading.
 - Improved how AI Studio works out what a model can do. Every model family now stands on its own, together with the page it was read from, and our build refuses rules which contradict each other or name no source. That way, mistakes are caught before they ever reach you.
 - 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.
+- Improved organization-wide provider management: IT departments can now separately prevent users from adding chat, transcription, or embedding providers. The existing master setting still overrides all three provider-specific settings.
 - 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 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.
