Apart from FreeBSD 7.0 RC1, RC2 of version 6.3 has been released too.
Sorry for the delay with this phase of the 6.3 release. A few glitches were found during testing of the 6.3-RC2 ISOs that included pre-built packages. The 6.3-RC2 builds for amd64 and i386 should now be available on the majority of the FreeBSD mirror sites. I just finished loading the sparc64 build so that will take a little while to propagate to the mirrors. This is the last planned RC for 6.3. Unless a major show-stopper problem is found the release of 6.3 should happen in about two weeks.
Release message, installation and upgrade notes can be found here.
