I avoided specifying an exact schedule; we need to have the flexibility
to adjust until we find a happy medium that both developers and users
are comfortable with.

A year ago I was talking about monthly releases. But since then the idea
has taken hold that we should always maintain a stable, release-ready,
branch. That makes it much less pressing that we release very quickly,
so I'm wondering if quarterly releases might be less hectic.

Yes. Regardless of the exact schedule, doing releases relatively often
and on a regular schedule will obviate a lot of the need for separate

But, and this is an important point, different sub-communities within
Boost may have their own reasons for wishing to schedule their main
release asynchronously compared to the main Boost releases. And as Boost
continues to grow that becomes more likely. So I really think it is
useful to be able to do separate releases, even if that facility isn't
used a great deal at first.

I'd like to think about your numbering suggestion above before
commenting on the specifics. But I do think that if we are going to
change how we number releases, now might be a good time to do it, and it
is certainly a good time to talk about version numbering.
