Revit 2012 Web Update 1 - What did it Fix?

 To quote Kathryn Langan's comment over at the Revit Clinic:
...the Update Enhancement List PDF that is typically provided is still being reviewed. It will be posted to the download pages once it is complete.

But what do we know right now?  At least two things have been fixed:

Mass Transparency fixed -
the Disappearing Act no longer works after Web Update 1 (which is a good thing!)

Point Cloud placement fixed -

What about you?  Have you noticed any improvements?  Feel free to comment.

Also, can anyone explain why Update 1 does not show up on the Updates page over at Revit Support?  It only shows up under Product Download...
