On http://gradle.org/documentation the box on the right says 1.0-milestone6, but links to milestone7.
No link from the website as far as I can tell to the issue tracker. Seems like that should be accessible from at least http://gradle.org/contribute, likely http://gradle.org/development and probably also help and support. Currently, the only way I can see to get to the issue tracker is via a link in the forums, which seems like more steps than it should take.
