For testing "check for updates"
and that "categories" are correct, I recommend you start with
"Mars" or "Mars.1" and that you disable all other repo
sites, and turn off the preference to "check
other sites for dependencies." That makes sure you are testing the
RC3 site only.
Assuming that works ok, I think recommend
you start over fresh, with all sites enabled, and the preference for "other
sites" enabled, and make sure you get the same results
and see the same things in 'categories.'
Moreover, don't forget -- you do not
have to test only your favorite projects -- try installing everything,
or, at least, some larger set, and make sure everything still works.

It is now past the time I say "test
early, test often." Instead, my motto for the next few weeks is "test,
test, and test again!" :) We want to avoid introducing regressions.
Plus, it helps if you 'verify' bug fixes,
especially all the worst ones (blocking, critical, major) -- and, also,
any new function.
Thanks as usual for making the improvements
to our (final) Mars update release possible.
