I have a question:

Can you give us some information on platform specific updates. I had heard about quite a few at last year's WTC and during the beta test, but I'm not sure what made the cut.

For OS X, it is pretty obvious that support for Retina displays is present, but I also heard that the front end was being rewritten in Cocoa, but I have no way to determine this.

Possibly related -- why is the front end still 32 bit?

I am sure that there are other interesting platform specific changes that users would like to know about.

I look forward to the talk.

Thanks.
