Bigger features:
- Chat (including paginated scrolling, mentions auto-completion and other nice tricks)
- Client certificate based authentication (super super awesome feature)
- Voice-only calls
- Significantly improved calls UI (e.g. avatars when remote video is disabled)
- Endless loading for contacts & Remote search
Please note that chat requires Talk 3.2 on the server side, at least. And the UI doesn’t expose voice-only calls unless you have 3.2 either.
Smaller features:
- Too many to count, but they include lots and lots of bug fixes and overall UI/UX improvements.
