0.21.6.1069 beta

- If you experience issues with some settings being lost (e.g. adding proxy – restarting app – added proxy is missing), please do Settings – Hold app version – Logs – Testing Utilities – Test database, then follow instructions. You can test database even if you don't have issues with it, it would be useful too.
- Added more asserts (crashes). This is needed in order to improve quality and kill certain bugs in future builds. Kindly be ready to encounter them. If crashes in beta are unacceptable for you, kindly do not update just yet or switch to production version.
- Fixed crashes
- Internal core changes related to database
- Improved crash reporting (internally) for certain kinds of issues in order to resolve them faster.
- Changing language now works properly in all versions. This does not require updating to 0.21.6.1069 and affects previous versions as well.

Updated TDLib:

- Fixed crashes
- Fixed updating poll when voting
- Improved group & channel members counters (both total & online)
