-### Update accident
-Update coincided with persistent state serialization event which lead to block production speed deterioration (issue substantially mitigated in update itself). This phenomena was aggravated by the fact that after update some validators lost ability to participate in block creation. The former was caused by threshold based hardcoded protocol version bump, where threshold was set in such manner (based on block height with value higher than 9m), that it eluded detection in private net tests. The update was temporarily paused and resumed after persistent state serialization ended and issues with block creation were resolved.
