 - 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.
+- Fixed AI Studio asking you to install Pandoc when you load a file as the input of an assistant, although PDF, Word, Markdown, and most other files need no Pandoc.
+- Fixed dropping a file onto your custom prompt guide in the Prompt Optimizer. Once you switch on "Use custom prompt guide", a marked area appears where you can drop your guide or select it with a button.
 - Upgraded several libraries to improve security.
 - Upgraded Tauri to v2.12.5.
 - Upgraded MudBlazor to v9.12.0.
