 - Added formulas in code blocks to the chat: when an AI model puts a single formula into a code block marked as LaTeX, the chat now shows the formula instead of its code. A code block with a LaTeX document or with text in it stays code.
 - Added buttons to copy and save the formulas in the chat. When you point at a formula, you can copy its LaTeX code or save it as a LaTeX file, and the export menu of an answer offers its formulas as well.
 - Added support for OneNote sections (`.one`): you can attach them to chats and assistants and use them in your local data sources. AI Studio reads every page, including the text OneNote recognized in pictures and handwriting.
+- Added the Mathematics tools as a prototype: the AI can now calculate exactly and work with formulas, right on your computer. It keeps fractions exact, gives results with up to 100 digits, solves equations, differentiates and integrates, and can check whether an integral really has the value someone claims. AI Studio checks the results numerically wherever possible, and the AI tells you when a result is only approximate. To try it, open the app settings, allow preview features down to prototype, enable Mathematics, and then choose Mathematics among the tools of a chat.
 - Improved the documentation for IT departments, which now lives in our [wiki](https://github.com/MindWorkAI/AI-Studio/wiki/Enterprise-IT). It is sorted by task, explains the setup on Windows, Linux, and macOS, and offers complete configurations for typical needs, such as using only local models. The link in the app settings leads there, and the wiki also holds the installation guide in English and German.
 - Improved the German translation throughout: we proofread all texts and corrected wrong labels as well as spelling and grammar mistakes. The texts now always address you formally and use the same terms everywhere.
 - Improved the security of the connection between the app window and AI Studio.

 - Fixed the result of a tool in the chat showing umlauts, quotation marks, and other special characters as codes instead of the characters themselves.
 - Fixed the Assistant Builder telling you in English why it could not use the answer of the AI model, even when you chose another language for AI Studio.
 - Fixed requests to a provider failing when a configuration plugin gave it additional API parameters that contain the same parameter twice. AI Studio now sends the request without these parameters and names the repeated parameter in its log, as it does for other invalid parameters.
+- Fixed the information page leaving out three libraries that AI Studio uses: MailKit and MimeKit, which read your mailboxes, and the Open XML SDK, with which the Slide Assistant reads and writes PowerPoint files.
 - Upgraded several libraries to improve security.
 - Upgraded Tauri to v2.12.5.
 - Upgraded MudBlazor to v9.12.0.
