Issue fixed in this release:

- Stability: ALTER KEYSPACE can break tables with UDT columns [#14139](https://github.com/scylladb/scylladb/issues/14139)
- 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](https://github.com/scylladb/scylladb/issues/13784)
- Stability: Shutting down auth service may hang [#13545](https://github.com/scylladb/scylladb/issues/13545)
