The issue with Boost Test is that if it now requires a C++11 level compiler to use it, every library which tests itself using Boost Test now requires a C++11 level compiler to run its tests.

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. Or they can freeze their Boost version completely continuing with the bugs they know and love. I suspect the Laggards will just muddle on? Meanwhile the Modernizers can muddle forward - it clearly isn't straightforward. I think that the current process is working OK just as Daniel James's updated guidance (good - thanks) suggests https://beta.boost.org/development/requirements.html#Backwards_compatibility Paul --- Paul A.
