Updates to existing EPEL/Fedora version should probably wait until at least
2.2.1 is out. I've seen at least one report of sharding problems with 2.2.0
that were confirmed by the developers and reported as fixed in trunk and to
be released in 2.2.1.
In general you should probably wait for at least one or two additional
releases to catch the most blatant bugs in the new major version.

In as-of-yet unreleased verions like Fedora 18 this is not such a big issue
since these will all be fresh setup and bugs will be noticed then and there
but someone who is running 2.0 for a while in Fedora 17 or Centos 6 should
not be hit by such things.
