[6.6.0.rc4] The next branch doesn't announce the release of 6.6.0 final

Not exactly a big issue but the Next Branch of the update system doesn't have a record of 6.6.0 being released so the first I knew about it was when I visited the forum.

Now I know that the differences between 6.6.0rc4 and 6.6.0 are negligible, but it would be nice if the next branch featured the final releases so that testers move from 6.6.0rc4 to 6.6.0 (final) and then to 6.6.1rc1.
