[boost] [1.45] Release notes

Hello all, Once more, it's time to prepare the release notes. If you want to add to them yourself, you can edit the source files in subversion here: http://svn.boost.org/svn/boost/website/public_html/beta/feed/history/ Or if you prefer, you can email me the details and I'll add it for you. Because the relevant web pages are now served as static files rather than as dynamic php pages, rebuilding the feeds won't change the web site. The process for generating the pages was a quick hack and is pretty horrible, so it's probably best if you leave that to me for this release. I'm writing a new python script to do all of this (the only requirement will be a quickbook executable), so hopefully it'll be a lot easier next time. Daniel
