The page on contributed module versioning is incorrect.

Issue Summary

http://drupal.org/node/467026

The page doesn't indicate that development releases are now versioned, nor does it explain the new version format of dev branches with {major}.{minor}+{commits since tag}-{dev}. I'd update the page, but I'm not sure if it's kosher to just go update the page or whether there is some sort of review process these days.
