We will be keeping the major.minor.micro version numbering. David is
not proposing to change that. What he is suggesting is that we try to
make these releases come out on a given schedule.

The semantics of major.minor.micro for numpy got confused because of
an early mistake (IMO) wherein we designated 1.1 as a release which
would allow code breakage. I would very much like to get away from
that and follow Python's model of only doing bugfixes/doc-enhancements
in micro releases, new features in minor releases and code breakage
never (or if we absolutely must, only after one full minor release
with a deprecation warning).

I think it is certainly feasible to roll out the bugfix releases on a
fixed schedule. I am less certain about the feature releases; I'm not
sure we gain much by it. Having a feature freeze policy is sufficient,
IMO. Once we've decided that we have accumulated enough features for a
release, we declare a feature freeze for a fixed period of time,
test/build/bugfix, then release. I think a fixed recurring time period
may simply encourage rushing features in without testing.
