- Added logic to eagerize unstable nodes in subquery delete.
- Update the list of valid timezones to include
Europe/Kyiv, as per IANA 2020b. - Fixed bug where
DROP DATABASE ... IF EXISTSandALTER DATABASE ... IF EXISTS ...could giveDatabaseNotFoundExceptionwhen there exists a remote database alias with the name. - Fix bug in pipelined runtime where some queries using AssertingMultiNodeIndexSeekOperator would fail incorrectly with
Merge did not find a matching node.... For example in queries likeUNWIND [0,1] AS id MERGE (n:A:B {id: id}), if there is a uniqueness constraint on the id property for both A and B labels. - Fix bug in pipelined runtime where AssertingMultiNodeIndexSeekOperator failed to perform locking index seeks. This could lead to failures when running concurrent transactions in queries like
MERGE (n:A:B {id: x})when we have a uniqueness constraint on id for both labels A and B. - Fixed bug for having * and order by id in same RETURN clause
