Scylla Open Source 4.2.1

The ScyllaDB team announces Scylla Open Source 4.2.1, a bugfix release of the Scylla 4.2 stable branch.
Scylla Open Source 4.2.1, like all past and future 4.x.y releases, is backward compatible and supports rolling upgrades.

Note that the latest Scylla stable branch is Scylla 4.2, and it is highly recommended to upgrade to it.

Issues fixed in this release:

  • Stability: some non-prepared statements can leak memory (with set/map/tuple/udt literals) #7019
  • Stability: secondary index updates failing after upgrade to 4.2.0 due to missing system_schema.computed_columns. The problem is limited to secondary indexes created before Scylla 3.2, which had their idx_token column incorrectly not marked as computed #7515
