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

- CQL: casting float to text resulted in too few digits. [#15127](https://github.com/scylladb/scylladb/issues/15127)
- CQL: Reject LIMIT without any value [#14705](https://github.com/scylladb/scylladb/issues/14705)
- Stability: seastar bug can cause aborted connection to loop, consuming 100% CPU. Among others, the issue can manifest in LDAP, nodetool drain. [#12774](https://github.com/scylladb/scylladb/issues/12774), [#7753](https://github.com/scylladb/scylladb/issues/7753)
- Stability: removing distributed loader prioritized keyspaces. This bug midget effect Encryption at Rest with a replicated key provider. [#11349](https://github.com/scylladb/scylladb/issues/11349)
- Stability: failure detector apis need to call gossiper on shard 0 [#15816](https://github.com/scylladb/scylladb/issues/15816)
- Stability: ScyllaDB contains two classes of tables, system and user, and uses separate memory pools for their memtables. This avoids a deadlock when a user memtable is being flushed, and needs to allocate memtable space for a system table as part of the flush process. We now [automatically designate](https://github.com/scylladb/scylladb/commit/eb368f9f6e03a6c019fb70c64da7b24a11975547) all system tables as using the system memtable pool. [#14529](https://github.com/scylladb/scylladb/issues/14529)
- Stability: migration\_manager: schema version correctness depends on order of feature enabling [#16004](https://github.com/scylladb/scylladb/issues/16004)
- Stability: [nodetool enablebinary](https://opensource.docs.scylladb.com/stable/operating-scylla/nodetool-commands/enablebinary.html) starts the CQL server in the streaming group, instead of statement group [#15485](https://github.com/scylladb/scylladb/issues/15485)
- Stability: nodetool resetlocalschema should recalculate per-table schema digest [#15380](https://github.com/scylladb/scylladb/issues/15380). With this change one can fix issues in Schema digest, like [#4485](https://github.com/scylladb/scylladb/issues/4485), without a rolling restart.
- Stability: Overloading scylla with materialized view writes can lead to deadlock [#15844](https://github.com/scylladb/scylladb/issues/15844)
- Stability: A rare crash when a SERVICE LEVEL is dropped [#15534](https://github.com/scylladb/scylladb/issues/15534)
- Performance: Repair-based node operations (RBNO) write SSTables with useless filters as a result of not feeding correct key estimation [#15748](https://github.com/scylladb/scylladb/issues/15748). In 2022.2 only the replace-node operation uses RBNO by default.
- Performance: Off-strategy compaction improves compaction for run-based compaction strategies reducing temporary storage requirements. [#14992](https://github.com/scylladb/scylladb/issues/14992).
- Performance: Optimization for avoiding bloom filter during compaction was reverted by [#14091](https://github.com/scylladb/scylladb/issues/14091)
- Install: scylla\_post\_install.sh: “[$RHEL]” does not work for RHEL, it only detects CentOS [#16040](https://github.com/scylladb/scylladb/issues/16040)
- Tooling: Old version of node\_exporter (1.6.1), updated to 1.7.0 [#16085](https://github.com/scylladb/scylladb/issues/16085)
- Tooling: update Java tooling, including new versions for
