 # v26.11.1, build 260 (2026-11-xx xx:xx UTC)
 - Added a setting for the size of the interface, which you find in the app settings. You can choose a size for each of your screens, and AI Studio switches to it when you move its window to another screen. Thanks, Paul Koudelka (`PaulKoudelka`), for this contribution.
+- 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.
 - 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.
