Hi, Can you please provide dome JIRAs for superior fixes and performance improvements which are present in 3.11.1 but are missing in 3.0.15.
In addition,could you also provide the probable implications of the open memory leak issue in Cassandra 3.11. CASSANDRA-13929: BTree$Builder / io.netty.util.Recycler$Stack leaking memory <https://issues.apache.org/jira/browse/CASSANDRA-13929> Is it still recommended to go for 3.11.
