Did any moves throughout the Generation get: Stronger, Weaker, More/less Accurate, more PP, or changed type?
And did any types change what they are effective against(I heard that Poison used to be strong against bug, are there any others?)

type changes with super effectiveness are here http://pokemondb.net/type not the moves
Gust went from a Normal Type move to a flying type move but thats the only one i know of
