[boost] [1.51][Release] Short release cycle

Hello everyone, Just a quick warning that due to the delay releasing 1.50, the 1.51 release cycle is going to be a lot shorter than normal. It's a little under 2 months until the scheduled 1.51 release date. This means that the deadlines are pretty soon. If you haven't checked it yet, please take a look at the calendar at: http://www.boost.org/community/ The current deadline for new libraries and breaking changes is 9th July, which is less than two weeks. If you do have a new library that want to release in 1.51, you should probably let us know very soon. thanks, Daniel
