[boost] [1.41] Release Notes

Hello everyone, Since we've more or less entered feature freeze, it's time to add any updates to the release notes. As always, you can just email me a line or two and I'll add it, ideally including the Trac tickets that have been fixed. Or if you want to do it yourself, the release notes directory is: https://svn.boost.org/svn/boost/website/public_html/beta/feed/history/ It would be best if you could do this before Sunday so that your changes will be included in the beta notes. thanks, Daniel
