Fixed issues in this release are listed below, with open source references, if present:
- Stability: in some rare cases, SSTable metadata in memory is not correctly evicted, causing memory bloat #4951
- CQL: a restricted column that is not in a select clause returns a wrong value #5708
- Stability: Node shutdown may exit when using encryption in transit #5759, seastar #727
- Performance: scylla doesn’t enforce the use of TSC clocksource #4474
- Stability: wrong hinted handoff logic for detecting a destination node in DN state #4461

- Install: scylla_setup does not present virtio-blk devices correctly on interactive RAID setup #4066
- Stability: malformed replication factor is not blocked in time, causing an error when running DESCRIBE SCHEMA later #3801
- Stability: In rare cases, and under heavy load, for example, during repair, ScyllaDB Enterprise might OOM and exit with an error such as “
compaction_manager - compaction failed: std::bad_alloc (std::bad_alloc)”. #3717 - Stability: possible abort when using reverse queries that read too much data #5804
- Stability: writes inserted into memtable may be interpreted using incorrect schema version on schema ALTER of a counter table #5095

- Stability: When speculative read is configured a write may fail even though enough replicas are alive #6123
- Performance: Allow tweaking of slow repairs due to redundant writes for tables with materialized views
- Stability, hinted_handoff: all nodes in the cluster become overloaded (CPU 100% loaded on all shards) after node finishes the “replace node” procedure
- Monitoring: streaming: Make total_incoming_bytes and total_outgoing_bytes metrics monotonic #5915
