There's a report that autolinking is broken for a fresh recursive checkout of master, due to b2 generating 1.57 libraries while boost/version.hpp still reports the version as 1.56. This commit setting BOOST_VERSION in Jamroot made it to master: https://github.com/boostorg/boost/commit/d9cf98c2074cf8a27017170375c5c825e48... While the corresponding commit for boost/version.hpp didn't: https://github.com/boostorg/config/commit/34e1c7416be2ede7d86f3dcc093a845809...
