Scientific Linux 5.5 x86_64 is now officially released and available.
We want to thank everyone who has contributed, tested, and given us
feedback. We say that every time, but we really mean it. Many of the 
features in Scientific Linux come from our community.  Without
everyone's contributions, help and testing, this release wouldn't be as 
good as it is.

More information can be found at the distribution web site
