- (CORE-3101)ALTER DOMAIN was not possible in a database that had been migrated from an earlier version.
- (CORE-3100)The WAIT mode and lock timeout parameters for the external transaction of EXECUTE STATEMENT were not matched to the corresponding parameters of the local transaction.
- (CORE-3096)A regression introduced with the fix for CORE-2893 caused double processing of nodes when preparing a statement, prompting an abort to occur in the debug build.

- (CORE-3090)Incorrect LEFT JOIN result using table and derived constant subquery.
