 # v26.6.3, build 243 (2026-06-xx xx:xx UTC)
 - Improved assistants so running tasks can continue when you leave the assistant and return later.
+- Improved the activity indicators for running chats and assistants so they use a consistent blue highlight.
 - Improved the chat experience by automatically focusing the message composer again when it becomes available. Thanks, Dominic Neuburg (`donework`), for the contribution.
