What I have noticed, but I dunno if it's just me or not (r4103): "Esc" key doesn't work any more in the beginning to skip the intro movie/screens - it used to do that before. Also, my existing key bindings didn't fully work any more. I am using keypad numkeys, and it seems with the new build these have different names so you have to remap several of them.
Other than that, if you use Polymer AND HRP, 64bit is definitely making a difference (I didn't see considerable improvements before since I wasn't loading HRP at the same time). Nothing less than a milestone, as far as I am concerned!
