- Updated libtgvoip to 2.4.4
- Fixed forwarding messages to secret chats
- Fixed poll does not update if changed by server immediately after sending
- [Probably] Fixed crash on pre-Oreo devices when using custom file for notification sound
- [Probably] Fixed missing badge counter near app icon
- Replaced some critical warning messages with asserts (crashes) for beta version. By crashing the app & sending feedback you help resolving the issue faster.
- Internal changes related to notifications when app is closed
- Switching language will work in this version, but will still produce an error. Sharing as XML and some other features for translators may not work properly, until this error will disappear.
