Iv seen people "complain" about 2.53

Since the release of 2.53 iv seen people having some problems…

So what exactly has been changed since 2.52?(bugs, drawbacks)

Edit: Or should i just stay with 2.49b when it comes to the game engine(ignoring the fact that its faster)

Its the wildly different interface, and thats about it, thats wat scares ppl. I dont really see any reason not to like it, but there have been times were i’ve become pretty frustrated:mad:. But thats the only reason, i know, that ppl dislike 2.5.
