 - Improved the safety of plugin symbols: AI Studio now shows the symbol of a plugin in isolation, so nothing inside a symbol can reach the rest of the app.
 - Improved how much memory AI Studio needs. Working with large documents used to grow the app to several gigabytes, and on macOS that memory was never handed back. AI Studio now stays at a fraction of that and returns memory to your system. This matters most on devices with little memory, such as a Raspberry Pi.
 - Improved the preview for large documents. It now shows you the beginning of your document instead of loading all of it, so the dialog opens right away. Your complete document still goes to the AI.
+- Improved how AI Studio deals with rare internal hiccups. When the app window reloads, or when it briefly loses the connection to its own user interface, work which was still running in the background is now ended properly instead of leaving errors behind.
 - Fixed AI Studio reading a document to the end even after you closed its preview. Closing the dialog now stops that work immediately.
 - Fixed AI Studio holding on to finished chats, presentation images, and plugin data. It releases them now, so memory no longer grows the longer you keep the app running.
 - Fixed assistants handing an outdated result to the chat. When you sent several results without opening the chat in between, you now receive the one you sent last.
