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.

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
