Issue fixed in this release: - Security: the new ScyllaDB image (GCP, AWS, Azure, Docker) includes a fix for [OpenSSH Vulnerability CVE-2024-6387](https://forum.scylladb.com/t/openssh-vulnerability-cve-2024-6387-mitigation/2257) - Stability: Off-strategy compaction is used to make sstables conform to the compaction strategy after an operation such as repair. Off-strategy compaction for TWCS will now have less storage space overhead. [#16514](https://github.com/scylladb/scylladb/issues/16514) - ADMIN API: using the admin REST API may lead to a crash with assertion `!\_end && !\_zc\_bufs && “Was this stream properly closed?”’ failed [#19494](https://github.com/scylladb/scylladb/issues/19494) - Stability: Batches (as generated by the BATCH statement) are held in the system.batchlog table. As this table can accumulate a lot of tombstones, we now take steps to ensure these tombstones are purged eagerly. This is important for repair, which replays the batch log. [#19376](https://github.com/scylladb/scylladb/issues/19376) - Packaging: Bundle cqlsh with support for “DESC SCHEMA WITH INTERNALS” [#18989](https://github.com/scylladb/scylladb/issues/18989). Also see [#19334](https://github.com/scylladb/scylladb/issues/19334) below. - CQL: DESC does not report [CQL Table Extensions](https://opensource.docs.scylladb.com/stable/cql/cql-extensions.html)[#19334](https://github.com/scylladb/scylladb/issues/19334) - Stability: chunked\_vector::reserve\_partial does not work as documented if size \> max\_chunk\_capacity() [#19254](https://github.com/scylladb/scylladb/issues/19254) - CQL: Disabling tablets using ALTER KEYSPACE should be forbidden [#18795](https://github.com/scylladb/scylladb/issues/18795). This was already non supported, but now blocked in the CQL level. - Performance: Statements such as SELECT count(\*) use an internal map-reduce service to parallelize the query. ScyllaDB no longer does so for single-partition queries as they don’t benefit from it. [#19349](https://github.com/scylladb/scylladb/issues/19349) - Stability: Failed to add node in parallel [#19523](https://github.com/scylladb/scylladb/issues/19523) - Stability: hinted handoff: Scylla may initialize endpoint managers for invalid hint directories [#19172](https://github.com/scylladb/scylladb/issues/19172) - Stability: init - Startup failed: std::runtime\_error (Failed to mark node as alive in 30000 ms …). The root cause is a node booting in gossip topology waits until all NORMAL nodes are UP. If we removed a different node just before, the booting node could still see it as NORMAL and wait for it to be UP, which would time out and fail the bootstrap. [#17526](https://github.com/scylladb/scylladb/issues/17526) - Topology Update: Scylla allows replacing a node in one dc/rack with a node in a different dc/rack which requires full cluster repair and then cleanup all nodes. This is now blocked, and you should start a new node and decommission the old one instead. Use Replace operation in the same DC/Rack only. [#16858](https://github.com/scylladb/scylladb/issues/16858) - Storage: ScyllaDB now use the latest [ME SSTable format](https://opensource.docs.scylladb.com/stable/architecture/sstable/sstable3/index.html) by default [#18995](https://github.com/scylladb/scylladb/issues/18995) - Stability: tablet storage is not freed when migrating a tablet replica away [#16946](https://github.com/scylladb/scylladb/issues/16946) - Stability: tasks: abort method hits use after free [#19304](https://github.com/scylladb/scylladb/issues/19304) - Performance: The gossiped view update backlog is only read on shard 0 [#19232](https://github.com/scylladb/scylladb/issues/19232) - Stability: View update generation times out during index building, wich result is redundant fake warnings.
