[boost] [1.39] Release notes

Hello all, If you haven't already, please can you add your release notes for 1.39. It's the same procedure as always, the notes are stored in 'boost_1_39_0.qbk' in the directory: https://svn.boost.org/svn/boost/website/public_html/beta/feed/history If you don't know quickbook please don't worry about the syntax, I'll clean up any problems and rebuild the page daily - all that matters is that your intent is clear. If for any reason you can't commit to the website then email your notes to the list and I'll add them. thanks, Daniel
