 # v0.9.7, build 182 (2024-09-09 xx:xx UTC)
 - Added the possibility to define multiple profiles in the settings. Use profiles to share some information about you with the AI.
+- Added profiles to the chat interface. You can now select a profile for each chat or even change the profile during a chat.
+- Added profiles to some assistants. It makes no sense to have profiles for, e.g., translation, etc.
 - Added an introductory description to the provider settings.
 - Added an indicator for the current and maximal length of the provider instance name.
 - Fixed the bug that the model name for Fireworks was not loaded when editing the provider settings.
