 - Added a start-page setting, so AI Studio can now open directly on your preferred page when the app starts. Configuration plugins can also provide and optionally lock this default for organizations.
 - Added math rendering in chats for LaTeX display formulas, including block formats such as `$$ ... $$` and `\[ ... \]`.
 - Added the latest OpenAI models.
+- Added minimum provider confidence settings for tools, so sensitive tools such as web search can be limited to trusted providers. Configuration plugins can also manage these defaults for organizations.
 - Released the document analysis assistant after an intense testing phase.
 - Improved enterprise deployment for organizations: administrators can now provide up to 10 centrally managed enterprise configuration slots, use policy files on Linux and macOS, and continue using older configuration formats as a fallback during migration.
 - Improved the profile selection for assistants and the chat. You can now explicitly choose between the app default profile, no profile, or a specific profile.

 - Fixed an issue where the app could turn white or appear invisible in certain chats after HTML-like content was shown. Thanks, Inga, for reporting this issue and providing some context on how to reproduce it.
 - Fixed security issues in the native app runtime by strengthening how AI Studio creates and protects the secret values used for its internal secure connection.
 - Updated several security-sensitive Rust dependencies in the native runtime to address known vulnerabilities.
