Issue fixed in this release:

- Stability: storage\_service::removenode should not silence exceptions [#11722](https://github.com/scylladb/scylladb/issues/11722)
- Stability: a rare issue when updating the schema more than once in once per millisecond [#13594](https://github.com/scylladb/scylladb/issues/13594)
- Stability: a rare crash due to null pointer dereference: clear\_gently of disengaged unique\_ptr dereferences nullptr [#13636](https://github.com/scylladb/scylladb/issues/13636)
- Stability: db/view: update view generator doesn’t close staging sstable reader on exceptions [#13413](https://github.com/scylladb/scylladb/issues/13413)
- Stability: direct\_failure\_detector::ping\_with\_timeout() causes exceptions to be thrown every 100ms times the number of live nodes, which spam the logs, and might slow it down [#13278](https://github.com/scylladb/scylladb/issues/13278)
- Stability: A [Seastar update](https://github.com/scylladb/scylladb/commit/42575340ba7ec573d22dd090a904b7ff1e2ead55) fixed an ambiguity in the http parser, which caused Alternator requests to be unnecessarily slow. [12468](https://github.com/scylladb/scylladb/issues/12468)
- Stability: Stability: Internal error in a COUNT request with empty IN. The query “select count(\*) from {table1} where p in ()” should result in the count 0, because the empty p in () matches no row. However, what we get in Scylla now is an internal error. [#12475](https://github.com/scylladb/scylladb/issues/12475)
- Stability: on\_internal\_error doesn’t log an error when not aborting [#13786](https://github.com/scylladb/scylladb/issues/13786)
- Stability: bad\_alloc (seastar - Failed to allocate 536870912 bytes) [#13491](https://github.com/scylladb/scylladb/issues/13491). Root cause is a logic fault causing the reader to attempt to read all the data, consuming all memory. Can occur during sstableloader/nodetool refresh, repair or range scan.
- Docs: information that BYPASS CACHE is not Enterprise-only feature [#13106](https://github.com/scylladb/scylladb/issues/13106)
- Docs: remove out of date info on the CDC page [#12964](https://github.com/scylladb/scylladb/issues/12964)
- Docs: remove unsupported sequential repair mode from docs. [#12132](https://github.com/scylladb/scylladb/issues/12132)
- Packaging: RPM package dependencies issue. When installing a specific version with yum/dnf, scylla-python3 version will not match the specified version, but the latest one. [#13222](https://github.com/scylladb/scylladb/issues/13222)
- CQL: Aggregate functions do not work on counter columns. [#12939](https://github.com/scylladb/scylladb/issues/12939). Note tha UDA and UDF are experimental in 5.1.x
