Where can I find the latest release of Boost.Build v2?

The main page (http://www.boost.org/boost-build2/) for Boost.Build has two links, one labeled "Download" and another labeled "Nightly build", but the page has a last revised date of Oct. 4 2007.  I also thought that I had heard somewhere that independent releases were suspended in favor of just bundling into the larger boost library packages.

We are wanting to use the tool to build our own source code (which ironically doesn't use boost... yet), but we have to go through a stringent authorization process for open-source projects which must be repeated, even for rather insignificant version changes.  I'd prefer to avoid that pain as much as possible.

Thanks for any help.
