Below is a list of performance and stability improvements and bug fixes, each with an open-source reference if available:

- CQL: Different token calculation functions for “empty” partition keys cause sstable reader to misuse index [#9352](https://github.com/scylladb/scylladb/issues/9352)
- CQL: Empty strings are now [allowed](https://github.com/scylladb/scylla/commit/16229959002cde23f031b4d3bba52061f0b76cb7) in materialized view partition keys. [#9352](https://github.com/scylladb/scylla/issues/9352)
- CQL: Wrong validation of blobs in INSERT JSON [#10114](https://github.com/scylladb/scylladb/issues/10114)
- CQL, batch statements, inserting a row with a null key column should be forbidden [#12060](https://github.com/scylladb/scylladb/issues/12060)
- Stability: [index cache] Multiple 800ms+ reactor stalls during nodetool cleanup (with index cache disabled) due to the local index cache not being evicted gently when \_upper\_bound existed. [#12271](https://github.com/scylladb/scylladb/issues/12271)
- Stability: A crash in Scylla memory management code, triggered by index file caching, [was fixed](https://github.com/scylladb/scylla/commit/7038dc7003ac64d393eb3f19da38c04cfab966a8). The bug was caused by an allocation from within the memory allocator, causing cache eviction to free memory. Freeing the evicted items re-enters the memory allocator in a way that was not expected by the code. Fixes [#9573](https://github.com/scylladb/scylla/issues/9573)
- Config: Before this release, updating static shares configuration parameters, compaction\_static\_shares and memtable\_flush\_static\_shares required a restart to apply. These updated parameters apply immediately now.
- Init: scylla\_setup “provisioning in a similar environment” message is missing a value for --online-discard parameter [#11700](https://github.com/scylladb/scylladb/issues/11700)
- Init: scylla-server fails to start on n2-highmem-16 (6000 GB) instance. Fixed by removing diskCount vs cpu restrictions.
