Best Moveset

Hey guys/gals, love the site and all the great information. Definitely my go to after catching a hoard of mon. Quick question, I notice that there are a lot more A moves for my mons' that weren't previously rated as good. Was there an mass update to the movesets? Would it also be possible to sign up for a notification that will let us know when these moves lose or gain a grade?

Thanks for all the info you provide!
