- DML operations on temporary tables would try to append the key for provider library, which could cause a memory leak. Bug fixed for MyISAM temporary tables, InnoDB temporary tables still have this issue, probably caused by upstream bug #67259. Bug fixed #1112514 (Seppo Jaakola).
- Bug fix for bug #1078346 introduced a regression. Foreign key checks were skipped in the parent table, which would cause the foreign key constraint errors. Bug fixed #1117175 (Seppo Jaakola).
