As mentioned here in the official press message from Microsoft
XNA 2.0 was released today after a very short beta phase which did only run for a few weeks.
You can download XNA 2.0 from Creators.Xna.Com
, but for now it just says "XNA Game Studio 2.0 will be available early morning, Thursday Dec 13th, 2007 PST.
". This will hopefully change soon ^^http://creators.xna.com/Education/GettingStarted.aspx
Since XNA 2.0 is now out I will talk about some of its new features shortly and comment a little bit about the new networking API and Xbox LIVE features. Stay tuned.
