This release contains a bug fix for UTXO set calculation during a reorg. It is therefore highly recommended to upgrade to this release to remove any chance of falling out of consensus with the rest of the network in the event of a reorg.
Following changes are also in this release:
Add new checkpoint at the hardfork block. This includes updating the UTXO set checkpoint which will take about six months off the --fastsync bootstrap time.
Expose --dbcachesize and --dbflushinterval config options. Increasing these numbers should increase the speed of IBD. Especially when running an indexed node.
Accept schnorr transactions into the mempool.
