+1.

It sounds like what we're going to communicate to users is that Boost library authors or maintainers are no longer required to make their libraries support C++03.

I didn't think that Boost Library authors were ever required to do this once subsequent C++ versions where released. Which sounds fine to me. I don't think

library maintainers should be confined by users (even if the users are other Boost libraries) if they don't want to be.

Any Boost library maintainers that wish to continue supporting their C++03 users will do so. Any other Boost library maintainers that depend on such libraries can drop the dependency on those libraries.

It can't really be any other way.

Glen

+1 (though I think this was always the case. But clarity is never bad?) Paul PS And I'd favour pushing forward from C++11 as quickly as possible. People should plan and budget to move forward every few years providing manpower, hardware and software resources to do so.
