This will be in the release notes:
Static-link build option added
The option to link Boost.Threads as a static library has been added back
with some limitations. This feature was originally removed because
boost::thread_specific_ptr required that Boost.Threads be dynamically
linked in order for its cleanup functionality to work on Win32
platforms. Several options are currently being explored to resolve this
issue. In the meantime, the ability to link Boost.Threads statically has
been added back with boost::thread_specific_ptr support removed from the
statically linked version. The decision to add it back was made because
its lack is one of the most frequent complaints about Boost.Threads and
because the other approaches that are being investigated to deal with
boost::thread_specific_ptr cleanup look fairly promising.
Boost.Threads is still dynamically linked by default. In order to force
it to be statically linked, it is necessary to #define
BOOST_THREAD_USE_LIB before any of the Boost.Threads header files are
If the boost::thread_specific_ptr cleanup issue cannot be resolved by
some other means, it is highly likely that the option to statically link
Boost.Threads will be removed again in a future version of Boost, at
least for Win32 platforms. This is because the
boost::thread_specific_ptr functionality will be increasingly used by
Boost.Threads itself, so that proper cleanup will become essential in
future versions of Boost.Threads.
