The patch fixed 2 long term bugs.
Firstly...we have only ever been able to power our mons up to 1.5 levels above our trainer level...it was always supposed to be 2 levels higher.
Second bug fixed is the ability for mons to be powered to lvl40.
Putting these together, you can now totally max out mons without any 'tricks' to lvl40 as soon as you hit lvl38.
Gotta max 'em all
