Pretty sure the AA Halftrack change is just an animation fix so that it doesn't look like the gunner decided to ram the gun through the drivers head while it's firing forwards.
All in all a solid patch. I'm glad to see that the Pak Howie's radius nerf wasn't as large as in the preview- at least it's larger radius somewhat justifies its cost and longer auto fire time.
Autoface nerf is good IMO, further rewarding players for good micro is a good thing. On many of the more narrow maps you should rarely need to re-position them anyway
