 - Added the ability to use file attachments in chat. This is the initial implementation of this feature. We will continue to develop this feature and refine it further based on user feedback. Many thanks to Sabrina `Sabrina-devops` for this wonderful contribution.
 - Improved the document analysis assistant (in preview) by adding descriptions to the different sections.
 - Improved the document preview dialog for the document analysis assistant (in preview), providing Markdown and plain text views for attached files.
+- Improved the Pandoc handling for the document analysis assistant (in preview) and file attachments in chat. When Pandoc is not installed and users attempt to attach files, users are now prompted to install Pandoc first.
 - Improved the ID handling for configuration plugins.
 - Improved error handling, logging, and code quality.
 - Improved error handling for Microsoft Word export.
