Hello, As requested, I've pushed the latest 'stable'(*) version of subquery optimizations into lp:~maria-captains/maria/5.3. (*) - stable here means: = there are no subquery-optimizations related failures in buildbot = there are no known "new" subquery issues (there are still some subquery code issues that were inherited from buildbot, though).
