I have just finished adding the last of the move changes to our Pokedex. Move tutor attacks and the handful of TM changes were done Friday. There were no egg move or HM changes in Black 2 & White 2.
Over the past few days I have been adding the level up move changes. Mostly these were just level changes, to account for the fact many early-generation Pokemon are available at lower levels than in Black/White. But several Pokemon got a new attack or two such as Sandslash with Earthquake, Drapion with Night Slash and Beartic with Aqua Jet. See this thread on Pokebase for just the new moves added, or browse the Pokedex below.
