| 01:07 | Improvements to "NOT IN (SELECT ...)" processing. Only test for NULL values on the RHS on the first iteration, then remember the result. There has been logic to do this for year, but it didn't work right and ended up repeating the NULL test on every iteration. This inefficiency was found using the VDBE coverage testing tools.
