Issue fixed in this release:

- CQL: Adding (using ALTER TYPE) a UDT field of type Duration doesn’t check whether it’s allowed. For example values of the duration type is not allowed for clustering columns [#12913](https://github.com/scylladb/scylladb/issues/12913)
- CQL: Changes to [tombstone GC](https://opensource.docs.scylladb.com/master/cql/ddl.html#tombstones-gc-options) (mode, gc period, etc) settings don’t take full effect till restart (or all sstables are recompacted). This is relevant when user switched from timeout to repair mode [#15643](https://github.com/scylladb/scylladb/issues/15643)
- CQL: a 5.4.0 regression in GROUP BY behavior [#16531](https://github.com/scylladb/scylladb/issues/16531)
- CQL: toJson() produces invalid JSON for columns with “time” type [#7988](https://github.com/scylladb/scylladb/issues/7988)
- Correctness: a rare combination of reconciliation (read repair) with reverse queries and range tombstones, could cause incorrect data to be returned from queries [#10598](https://github.com/scylladb/scylladb/issues/10598)
- CQL: System functions like count() don’t work anymore for custom roles after upgrading to 5.4.0. The root cause is a regression in 5.4.0 requiring EXECUTE permission for native function like count() [#16526](https://github.com/scylladb/scylladb/issues/16526)
- Setup: dist: ‘ordering cycle’ on var-lib-scylla.mount might be wrong, resulting a potential wrong init order of dependencies, like file system and scylla service booth. [#8761](https://github.com/scylladb/scylladb/issues/8761)
- Docker: can not connect to Scylla 5.4 with CQLSh without providing host IP [#16329](https://github.com/scylladb/scylladb/issues/16329)
- Docker: upgrade all 3rd party packages on creation [#16222](https://github.com/scylladb/scylladb/issues/16222)
- Stability: A regression in IPv6 address formatting, which caused nodetool problems, like breaking when there is an Alternator GSI in the database [#16153](https://github.com/scylladb/scylladb/issues/16153), or cause a node to be stuck with “?U” status and Host ID is "null [#16039](https://github.com/scylladb/scylladb/issues/16039)
- Stability: Use statement might throw an exception instead of returning an exceptional future, for example if the keyspace is doesn’t exist [#14449](https://github.com/scylladb/scylladb/issues/14449)
- Java Tools UX: Improve error message when a Java base SSTables tools, like sstablemetadata, hit a new uuid-based identifier introduced in 5.4.0 [scylla-tools-java#360](https://github.com/scylladb/scylla-tools-java/issues/360)
- Java Tool: Old version of libthrift and others dependency [scylla-tools-java#352](https://github.com/scylladb/scylla-tools-java/issues/352)
- UX: no appropriate error when AuthenticationFailed due to consistency level does not match(system\_auth) [#2339](https://github.com/scylladb/scylladb/issues/2339)
