I'm a little confused by the naming convention of this release... in several places, the announcements say "released" and "shipping." -- the filename still includes "RC" -- does "RC" in this case not stand for Release Candidate?
Talisman is correct.
Released means that it is publicly available for download and use, and shipping refers to the same thing. Meaning, grab it, use it, love it.
Talisman is correct, and it is proving to be a very, very stable release.
