MySQL

If a DATE or DATETIME column contains a value that isn't a valid date or datetime (for example, a zero date like 0000-00-00), we now preserve the original value by promoting the column to STRING instead of syncing it as NULL.

If you have type locking enabled on a connection, this promotion doesn't happen — invalid values are synced as NULL instead, and the column keeps its original type.
