I believe now is the time we start establishing the infrastructure to shape the new Boost 2.0 distro instead of wasting resources on trying to refactor the 1.x distro. APIBind is there for maintainers wanting to be part of both distros. Let's make a clean break.

Allow me to bring up a point I have been trying to make for quite a while: Why does Boost need a single "distro" ? Assuming a full breakup of boost libraries with well documented (and encoded) dependencies among them, I think a much more viable solution for everyone would be to let each boost library become its own project with its own release schedule etc.

So Boost would be merely an umbrella organization, and what you call a distro may be the repository of Boost libraries.

Wouldn't that be something worthwhile to think about and discuss ?

It is definitely worth discussing. The key is "with well documented (and encoded) dependencies among them".

How do we do this ? '

It is silly to suppose that new "Boost" libraries will be developed that do not depend on other already existing Boost libraries. If library X depends on library Y we currently know that library X will work with library Y for Boost distro N because we have tested them before we release distro N. If library X goes off with its own release schedule how do we determine with which versions of Y it will work when it is being released ?

This is the crux of the matter if we have individual Boost libraries being released on their own.

There wouldn't need to be a "we" to determine that. X version 1 (X1) would depend on Y1, when Y upgrades to Y2 then it's up to X to check if X1 works with both Y1 and Y2 or just Y1. If not then it could make a X2 release to support both Y1 and Y2. The key is not to try and prevent versioning issues, but to be able to handle it. Linux, pyhton, node all handle it, And that makes them robust tools with lots of libraries, also libraries that fork and compete, or fork so that better support is given by a new team.
