-- Fixed a bug where concurrent updates to a table using multiple column families during a partial index creation could result in data loss, incorrect `NULL` values, or validation failures in the resulting index. #168782
 - Fixed a bug that would allow a race condition in foreign key cascades under `READ COMMITTED` and `REPEATABLE READ` isolation levels. #169973
 - Fixed a bug that allowed foreign-key violations to result from some combinations of concurrent `READ COMMITTED` and `SERIALIZABLE` transactions. If both `SERIALIZABLE` and weaker-isolation transactions will concurrently modify rows involved in foreign-key relationships, the `SERIALIZABLE` transactions must have the following session variables set in order to prevent any possible foreign-key violations: 
   - `SET enable_implicit_fk_locking_for_serializable = on;`
   - `SET enable_shared_locking_for_serializable = on;`
   - `SET enable_durable_locking_for_serializable = on;` #169973
