This version is mainly a bugfix release. It also adds a few smaller improvements and features:
- Set an individual ringtone for each contact
- Set password for key revocation directly from within the app. If your ID gets lost or stolen simply revoke it on https://myid.threema.ch/revoke
- Widget to display unread messages on desktop or lock screen
- Bug fixes and improvements
The voice message plugin was also updated to 1.1. It now allows you to preview recorded voice messages before sending them.
