WHAT'S NEW IN XNA GSE V1.0 "REFRESH"?

... if that's the question you've been asking your-self lately, then you need to pay a visit to at least the following three sites:

• XNA GSE 1.0 Refresh ReadMe: of course.
• Let's Kill Dave blog: list of "big" things pointed out by Dave.
• The ZBuffer site: Andy publishes a handy list of changes in the API.

Of course, you should also check XNA Creators Club Forums, since there have some questions on issues while installing, updating past code and so on.

Hope it helps.
