The following issues are fixed in this release (with an open-source reference, if available):

- Alternator: Scylla Enterprise 2022.2.0 prompts [Alternator TTL](https://docs.scylladb.com/stable/alternator/compatibility.html#time-to-live-ttl) to production. It was not enabled by default. Now it is. [#12037](https://github.com/scylladb/scylladb/issues/12037).
- Setup: fix a regression in setup, which overrides the manual update of perftune.yaml [#11385](https://github.com/scylladb/scylladb/issues/11385) [#10121](https://github.com/scylladb/scylladb/issues/10121)
- Setup: updates in perftune.py, improving performance for larger servers (32 cores and above)
  - introduce a generic auto\_detect\_irq\_mask(cpu\_mask) function
  - auto-select the same number of IRQ cores on each NUMA

- Stability: ALTER KEYSPACE can break tables with UDT columns [#14139](https://github.com/scylladb/scylladb/issues/14139) (introduced in 2022.2)
- Stability: Crash on compaction completion when staging directory is reshaped and ICS ends up with a run containing staging and non-staging files.
- Stability: Shutting down auth service may hang [#13545](https://github.com/scylladb/scylladb/issues/13545)
- Stability: ‘sleep\_aborted’ error during Scylla shutdown [#13374](https://github.com/scylladb/scylladb/issues/13374)
- Stability: possible use-after-move in virtual table for secondary indexes [#13396](https://github.com/scylladb/scylladb/issues/13396)
- Stability: possible use-after-move when initializing row cache with dummy entry [#13400](https://github.com/scylladb/scylladb/issues/13400)
- Stability: possible use-after-move in virtual table for secondary indexes [#13396](https://github.com/scylladb/scylladb/issues/13396)
- Stability: possible use-after-move when making streaming reader [#13397](https://github.com/scylladb/scylladb/issues/13397)
- Stability: possible use-after-move when reading from SSTable in reverse [#13394](https://github.com/scylladb/scylladb/issues/13394)
- Stability: possible use-after-move when tracking view builder progress [#13395](https://github.com/scylladb/scylladb/issues/13395)
- Performance: Compaction manager “periodic reevaluation” is one-off. This means that compaction was not kicking in later for a table, with low to none write activity, that had expired data 1 hour from now. [#13430](https://github.com/scylladb/scylladb/issues/13430)
- Performance: Compaction manager can cause reactor stalls during periodic submission [#12390](https://github.com/scylladb/scylladb/issues/12390)
- Performance: ScyllaDB uses an interval map data structure from the Boost library to quickly locate sstables needed to service a read. Due to the way we interface with the library, updating the interval map was unnecessarily slow. This is now [fixed](https://github.com/scylladb/scylladb/commit/169a8a66f282cb420197f446134c61760f1a087b). [#11669](https://github.com/scylladb/scylladb/issues/11669)
- Performance: SSTable set is left uncompacted post off-strategy compaction completion, which may lead to suboptimal read and space amplification until the next compaction [#13429](https://github.com/scylladb/scylladb/issues/13429)
- UX: non informative iotune warnings in scylla\_kernel\_check [#13373](https://github.com/scylladb/scylladb/issues/13373)
