Update issued in the last week (June 1st, 2013?)

After I had to download a rather large (220 MB) update, I noticed some of the cards appeared to have different strengths. For example, Khlint used to be a very usedful "Enemy hero takes 2 damage when Khlint is sacrificed". It is now a more tedious "When Khlint is sacrificed, hero's minion takes 1 damage and enemy hero takes 1 damage". Do we have an idea of other changes?
