2.3.0

For this release, we now upgrade the RocksDB to 7.9.2 which will significantly improve the compaction performance. Another to be noticed, Kvrocks cluster mode will persist the cluster nodes' topology in the local file by default, you can disable it in flight by config set persist-cluster-nodes-enable no.
