 # v26.3.1, build 235 (2026-03-xx xx:xx UTC)
-- Added support for the new Qwen 3.5 model family.
+- Added support for latest AI models, e.g., Qwen 3.5 & 3.6 Plus, Mistral Large 3 & Small 4, OpenAI GPT 5.4, etc.
 - Added a slide planner assistant, which helps you turn longer texts or documents into clear, structured presentation slides. Many thanks to Sabrina `Sabrina-devops` for her wonderful work on this assistant.
 - Added a reminder in chats and assistants that LLMs can make mistakes, helping you double-check important information more easily.
 - Added the ability to format your user prompt in the chat using icons instead of typing Markdown directly.
 - 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.
