Not denying the FAQ usefulness, I can answer these questions.
No breaking changes have been made, all the code that previously
compiled should keep compiling.
boost/utility/empty_deleter.hpp has been deprecated in favor of
boost/core/null_deleter.hpp. Including the deprecated header will
display warnings pointing to the new header. Eventually (not in 1.56
for sure) empty_deleter.hpp will be deleted.
Implementation from all headers that were moved to Boost.Core is now
in boost/core. The old headers now simply forward to the new ones
(without warnings). It is recommended to include the new headers
directly, although the changes are not necessary. I'm not sure if
we're going to deprecate the old headers, but if we will, I'd say we
should add warnings first to start the deprecation period.
