A list of stability improvements and bug fixes below, each with open source reference, is available:

  • CQL: Scylla now correctly rejects CQL insert/update statements with NULLs in key columns. #7852
  • CQL: paxos_grace_seconds table option: prevent applying a negative value #7906
  • CQL: Secondary Index-based queries yield less data than they should if base queries are short-reads #9198
  • Install: scylla_setup failed to setup with error /etc/bashrc: line 99: TMOUT: readonly variable #8049
  • Install: GCP: scylla_io_setup generates invalid io_properties.yaml on n2-highmem-48 instance with 24 SSDs #9429
  • Install: scylla_io_setup on GKE: fails with workload identity enabled, since 4.3.x #9471
    Init: scylla can’t start when running in ARM based ami image #9493
  • Install:  scylla_raid_setup: failed due to the “mdmonitor.service: Failed with result 'protocol'” on CentOS8  #9540
  • Performance: stalls in repair caused by unnecessary copy #8902
  • Performance (ARM): computing probabilistic read repair decisions when probability is 0 inefficient for ARM #9107
  • Docker: stopwaitsecs missing from scylla-server supervisord config #9485
  • Admin REST API: /storage_service/repair_status invalid status code when repair id not found #9576.
  • UX: Uninformative error messages when client connects with wrong TLS version #8827,
  • TLS handshake retry should on repeated failure retain original exception. Seastar #911
  • Stability: The multi-shard combining reader is responsible for merging data from multiple cores when a range scan runs. A bug that is triggered by very small token ranges (e.g. 1 token) causes shards that have no data to contribute to be queried, increasing read amplification. #8161
  • Stability: Set gossiper scheduling class explicitly #7154
  • Stability: SSTable kl writer creates the index incorrectly, causing reads to miss range tombstones #9690
  • UX: workload prioritization: Reduce the logging sensitivity
  • Stability: Reshape stop API not working for TWCS tables #8755
  • Stability: transport: Fix abort on certain configurations of native_transport_port(_ssl) #7866 #7783
  • Stability: Failed fromJson() should result in FunctionFailure error, not an internal error #7911
  • Stability: segfault due to corrupt _last_status_change map in cql_transport::cql_server::event_notifier::on_down during shutdown #8143
  • Stability: possible Fix use-after-free in gossip real_mark_alive and mark_dead #8859
  • Stability: a bug in CDC log forced a non optimized execution path (but did not hurt correctness) #9103
  • Scylla Manager uses this API. The issue is mitigated for earlier versions of Scylla with Manager 2.5.4
  • Stability: Bloom filter memory consumption can be increased with segregation on memtable flush #9581
  • Stability: background reads out-living the parent reader can access freed range and slice #9719
