- Support for error objects crossing DLL boundaries on Windows via BOOST_LEAF_CFG_WIN32=2. - Internal TLS interface improvements, separating logical allocation from reading. - Dynamic allocations (if enabled) for on_error objects now happens before stack unwinding begins. - BOOST_LEAF_SYMBOL_VISIBLE declarations now separated in config/visibility.hpp.
