 - Added the ability to load a system prompt from a file when creating or editing chat templates.
 - 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.
 - 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.
