Subject Re: [DISCUSS] : Apache Falcon minor release schedule

After observing both formats across several releases I have also become a
strong supporter of Approach #2.
Releasing early has improved the project in many ways. Earlier we were
making releases after several months and we didn't invest time in improving
the release and testing process. Early release forced us to invest time in
these tasks and we have seen continuously better release candidates across
last several releases.

As for incomplete features going in, as Srikanth said this is a non-issue
as long as we don't advertise those features being available and in
practice it has been working out very well for us. Unlike approach 1 it
encourages us to follow the Apache way by putting in small changes in
community instead of dumping large features at the end and pushing them in
to make in a release. It also helps us to get quick feedback on changes
instead of making assumptions and making large changes based on those

Approach 1 also blocks certain changes if they are not supposed to be in
the release or will affect a feature marked for the release. Though
infrequent, in practice this hampers the community contribution in some
