 - Added a slide assistant, which helps you turn longer texts or documents into clear, structured presentation slides. Many thanks to Sabrina `Sabrina-devops` for her wonderful work on this assistant.
 - Added a reminder in chats and assistants that LLMs can make mistakes, helping you double-check important information more easily.
 - Added the ability to format your user prompt in the chat using icons instead of typing Markdown directly.
+- Added the ability to load a system prompt from a file when creating or editing chat templates.
 - Improved the profile selection for assistants and the chat. You can now explicitly choose between the app default profile, no profile, or a specific profile.
 - Improved the performance by caching the OS language detection and requesting the user language only once per app start.
 - Improved the chat performance by reducing unnecessary UI updates, making chats smoother and more responsive, especially in longer conversations.
