 - Added a way to copy an entire chat, either with the button in the chat toolbar or next to the chat in the chat list. The copy opens right away so you can continue in it, while the original conversation stays exactly as it was. Many thanks to Peer Hogeterp (`peerschuett`) and Jens Erler (`j-erler`) for this feature.
 - Added a way to roll a chat back to an earlier AI response. The response you pick stays, and every message after it is removed permanently, together with the attachments of those messages.
 - Added a way to save a single code block of an answer. When an answer holds a web page, a LaTeX document, or a Markdown text, the export menu now offers that block as a file of its own.

           <li>Fixed instructions slipping past the protection against prompt injection when invisible characters were hidden inside their words. Removing those characters used to put such an instruction back together unnoticed.</li>

           <li>Upgraded the Visual Briefing assistant (in preview) from the prototype to the beta state. The assistant is now completely implemented and is undergoing a deeper testing phase in preparation for release. To try it, open the app settings, allow preview features down to beta, and then enable the Visual Briefing assistant there.</li>
