So, unless this requirement is lifted, the Rubicon has already been crossed...

In a sense, yes, but Boost.Test C++03 from release 1.66 still exists.

So those who stay with C++03 won't be able to rely on the tester-runners to test updated libraries, but they can still use Boost.Test C++03 to run the test themselves - if they care.

The practical effect of Boost.Test requiring C++11 will be that everything C++03 in the test matrix (using Boost.Test) will fail.

We'll have to deal with that in some way. One option is to just stop testing C++03. Another is to migrate the libraries away from Boost.Test. Yet another is to do nothing and pay no attention to failures.

Number two is the only option making any sense to me,

Are you serious? I committed to maintain Boost.Test, not to burry it. Boost.Test **does** support C++03 and C++11. Boost.Test has values in the C++ testing ecosystem, there is no point in killing it. The initial question was a technical one, something that did not appear obvious to me about mixed APIs spanning several dialects. I am not asking for people to tell what the fate of Boost.Test should be: I am well aware that Boost.Test needs to continue supporting C++03, I am taking care of that. And yes, Boost.Test is used by people outside the Boost community.

but keep in mind that many of the affected libraries have no active maintainers, and the CMT is not terribly underworked.
