About Signal Desktop
Signal Desktop's beta returns to fix-only notes a week after its unread-filter release.
Signal Desktop ships a beta roughly weekly, and most builds since September have carried only generic fix notes. v8.32.0-beta.1 was the exception, extending the unread filter into folders and search and making uploads sturdier on poor connections; v8.33.0-beta.1 goes back to boilerplate. The previous visible gain was lighter CPU use in video calls on October 1.
