In this release

This release contains an important fix and is highly recommended for all miners and those who broadcast transactions via their node's REST API. However, it does not contain any consensus changes, so it is not required to update your node. There's no need to rebuild state when upgrading from 1.x.

UTX Synchronization Fix

This release fixes an issue with unconfirmed transaction synchronizer, which sometimes caused the node not to include any transactions or include little amount of transactions in the blocks it forges. Most of the recent empty blocks on the blockchain were caused by this issue.

REST API Improvements

• the above issue also caused sporadic "Error is unknown" errors when broadcasting transactions via REST API. Since the root issue has been fixed, transaction broadcast reliability should improve
• Swagger documentation for /transactions/status method has been fixed, which makes it usable via the web interface.
