I would like to request advise from the release managers and of course the Boost community. Should I rollback the default to BOOST_THREAD_VERSION==3 for 1.53 and let the time to discuss the best way to manage with these breaking changes?
Given that the breaking changes are due to alignment with C++11, I think that this is a good reason to break compatibility per default. Users have upgraded to a new version of Boost, so some upgrade cost is expected. If users are unwilling (or unable) to upgrade their implementation, they can easily revert to BOOST_THREAD_VERSION 2.
No, they can't. Some users use the Boost libs provided by their (Linux) distribution. They can't just #define BOOST_THREAD_VERSION 2 If I move from boost::thread to std::thread then yes, I'm expecting some costs moving. But merely 'upgrading' Boost, which might not require any action from the developer himself, should not come with such costs. -- Olaf
