Version 2.1.3 was released today. Change log:

• Removed v.2.1.1 debug logging that caused a crash on start-up on fresh installations (when no blocks had been downloaded yet).
• Fixed: Occasionally a staking node with a sometimes unstable or slow network used to get stuck on its own chain for up to 2 hours.
• Less kernel debug logging unless asked for.

Updating to this version is recommended but optional.
