I've put it on the site, the documentation is linked from the release notes:

When I tried to compile this release candidate the compilation failed:

libs/serialization/src/archive_exception.cpp:33: error: ‘m_msg’ was not declared in this scope

Currently I have no problems with 1.49.0.

The change that is causing the problem seems to be boost/archive/archive_exception.hpp.  In a quick comparison, it appears that char m_buffer[128] is supposed to replace std::string m_msg.
