By support I meant specifically _bug fixes_. You can already
download all previous released versions from the website and in
no way am I arguing to change that policy.
Even if we ever get to a point where we don't want to keep older
releases which I doubt very much (each zip is only a few MBs and
therefore insignificant on today's storage) - we could still
easily just checkout the specific release tagged in git and just
build that.

This is precisely what I addressed bellow. we have monthly build
of our staging branch - call them monthly betas that include new
upcoming features that are already stable enough to be released
to the public for field testing and are tentative for the next
actual release but until these feature actually get to a release
they hold no guaranties and can be further modified based on the
wider public testing - including changes in API. Once released,
they do hold such guaranties of API stability. So these monthly
betas will provide preview of language changes and allow people
to prepare for future changes and also provide feedback.

See comment above. the pre-release will contain new features
already stable enough to be consumes by the general public
_before_ we the developers are ready to a commit finally to their
API. E.g. Walter's release of DMD with attributes that was
already tested and working but after release people argued about
changing its syntax from [attributes] to @(attributes).
developers can have their own experimental branches for their own
tests and new ideas, but once a feature reaches pre-release it
should already be tested and working and ready for public
consumption without commiting to a final API.

I really don't care about the numbering scheme and this is
irrelevant to the topic of this discussion. We are discussing the
PROCESS of development. How the releases are tagged is completely
beside the point and could be named after sweet delights, cat
names, Parks or even digits of PI. I really don't care and it
really is _not important_.
This is one of those fundamental things that are required to
truly understand git - versions are the _content_ (code) they
contain and are identified by a hash of that content.
This is pure bikesheding but why not: Why not extend the
astronomical theme to releases as well? What would you say about
the latest Pluto release of DMD? ;)
(Yeah, I know this is already used by the eclipse project..)
