In this release
Dedicated discarded transaction queue
When the node appends a new key block which references one of older microblocks (not the most recent one), it will now store transactions from discarded microblock(s) in a dedicated queue. If it is this node's turn to mine the new block, the miner will first attempt to pack transactions from this queue into the new microblock. This change will improve the reliability of the network, because transaction ordering will be preserved across microforks, which implies that "dependent" transactions will less likely be discarded.
This change also affects the way miner mines key blocks. If NG is activated, the miner will never attempt to include any transactions in the key block. Actually, this was the default behavior since the beginning of NG, but in this release we have removed max-transactions-in-key-block setting.
REST API Improvements
- Swagger UI version has been updated. Besides new looks, this update brings a fixes XSS vulnerability (see #2693). We have also updated API schema with proper request and response model definitions.
- Fixed an issue which resulted in an "Error is unknown" response when broadcasting transactions
This is a maintenance release, however we encourage all miners to update due to improvements in the way dependent transactions are handled. There's no need to rebuild state when upgrading from 1.1.x.
