Unified Announcement and MVVMCross

I am new to MVVMCross and ~6 Mos with Xamarin…
From the Xamarin blog post today : http://blog.xamarin.com/unified-api-and-64-bit-support-complete/
What does that mean as far as MVVMCross is concerned?
I am using MVVMCross 3.2.2 Xamarin Forms (Android, iOS, WinPhone 8.0) and added a Universal Project for Windows Store/Phone 8.1.
