Well, I maintain serveral of my own internal and mirroring
repositories and this change caught me terribly offguard. I second
the idea (although it won't do any good, but whatever) that this
should be called yum3 or something. It's a major change. In
particular, it doesn't support old yum-arch created repositories
anymore. This requires additional server side work -- not always

freshmeat is quick to update, this is good, but unfortunatly the
rest of the repos out there might not be so quick.

Version numbers may be arbitrary, but there is a general consensus
that bumping the major number means something "significant"
happened. No supporting yum-arch made repositories is quite

Atleast a repository can be yum2 and yum3 compatible at the same
time. I have boat loads of yum2 machines in house that I never want
to have to install additional software (read: yum3) except for the
security updates I have yum doing via cron now.
