What did you do with 0.17?

I don't see an reason for someone to be concerned about skipping 0.22 and 0.21 release. We moved beyond it. Couple of lines in the release twiki should suffice. I run clusters for reasonably varied users, this hasn't been an issue.

When the decision was made to use HA branch as for 2.0 instead of base 0.23 branch, there was expectation that we would move to stabilize 0.23 by Feb 2012 and move to 2.0 in April. But unfortunately it took longer than expected. There is lot of
effort went in to getting 0.23 in to a state where we can start deploying to production.

We don't what to go to the same state as with 0.20.1xx. There are quite an number of folks who what to use a release of what Yahoo! runs in production. In the last 5 years, with the exception of some 0.20 release, we published via apache.

Its up to the PMC to decide whether to publish or not to.
