Just a bit of a guess, but if it is anything like the other main RPM based distros it will update individual packages as they are released (often to cure bugs or security issues) but the base information will still stay as the RC version
The only distros that seem to do the update "properly" are either debian/debian based (because "APT" is an excellent piece of work) or gentoo.
Of course, it's been a couple of years since I used an RPM based distro, it may have changed
