ScyllaDB Open Source 4.2.1

The ScyllaDB team announces ScyllaDB Open Source 4.2.1, a bugfix release of the ScyllaDB 4.2 stable branch.

Note that the latest ScyllaDB stable branch is ScyllaDB 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 ScyllaDB 3.2, which had their idx_token column incorrectly not marked as computed #7515
