Is there a document online that covers new features that will be introduced in Boost v1.40? If not, can someone provide a brief overview? Thanks.

There sort of is, but it is not obvious, nor is it yet complete. The Review Schedule includes information on when libraries are reviewed, accepted, and added to SVN so they can become part of a release. During the time that the release branch is open for changes, any library that is in SVN, but has not been released yet will be added as long as the tests go well enough to justify adding it. This becomes complete information for the next release once the branch closes for major changes. This isn't the most convenient way to do things for users, but it is a reflection of the way boost libraries happen. There is no central planning group deciding what will be in Boost when it is released. Instead, each release contains the libraries that have been accepted by the community and revised by the submitter until they are ready for inclusion. John
