When did this happen?

Before Big Bang comes along, I'd like clarification on some things that were changed when I came back from a 2 year break.

When I came back on Winter 2010, I noticed that every map's monsters in Victoria Island were changed. For example, there used to be Green Mushrooms in HHG1, Stone Golems on the way to Sleepywood, Copper Drakes in Dangerous Valley 1 (used to train here from 40-50) and Fire Drakes in Dangerous Valley 2, and the infamous Horned Mushroom tree (loved that tree). Another thing was the skills like, Double Stab does a cross slash animation, Lucky Seven's animation looks terrible now, Savage Blow apparently goes 4-5-6 hits instead of 2-4-6.

When did these changes occur?
