New: disappearing messages. Set a per-conversation timer, from 1 hour to 4 weeks or off, and new messages delete themselves when it elapses. The setting syncs across your own devices.
This release also brings the Android client to parity with the latest iOS build: remembered remote invites that finish after you close the invite screen, a Report action on the conversation list, clearer errors when a message cannot be opened, and no relay traffic while the app is locked.
First public source release, under Apache-2.0.
