I check the Seam download page, as I do every morning, and saw Seam 2.0.1 GA, with zero downloads! Well, now there has been one download and I'll switch my app over this morning. I have been using CR1 and CR2 and they have been fine. Congratulations Team Seam.
If you really want to be the first one, you should monitor the maven repository. We usually update the repository before updating the SF downloads. :)
