[boost] [1.52] release branch reopened for bug fixes ONLY

Now that we have released the first beta, the release branch is open for bug fixes. Only bug fixes, please.[*] No new features. No new libraries. You do not need a release manager's approval to merge a bug fix. The earlier you can merge your bug fixes, the better. The branch will close again for final release preparations on Oct 29. As usual, you can see the release calendar here: http://www.boost.org/development/index.html [*] Changes to documentation are always allowed. -- Eric Niebler BoostPro Computing http://www.boostpro.com
