Issue fixed in this release:

  • Stability: a lot of lsa-timing log messages during node replace cause c-s stuck and aborted. The fix update the reactor shares for default IO class from 1 to 200 #13753

  • Stability: ALTER KEYSPACE can break tables with UDT columns #14139

  • Stability: All rpc::client objects have to be stopped before they are destroyed. Currently this is done in messaging_service::shutdown(). The cql_test_env does not call shutdown() currently. This can lead to use-after-free, leading to sigsegv #12244

  • Stability: Level compaction is not working in cleanup #14035 (introduced in 5.1)

  • Stability: Range-scans have a protection against using the wrong service-level to continue a suspended range-scan. This protection had a mistake, resulting in the node crashing when the protection mechanism was triggered. multishard_mutation_query: reader_context::lookup_readers() is not exception safe w.r.t. closing readers #13784

  • Stability: Shutting down auth service may hang #13545
