Google have switched to their own 'forever'
version for now, based on
5.0.37 iirc :) It is just us!
Why Google uses branching to such an old version? Aren't the fixed
being backported to latest builds of 5.0.x (there was quite a time since
5.0.37).
As for MySQL 6.0, maybe it's worth a dedicated Database.php class for
the testing purposes..
