How to distribute releases
ManifoldCF's release area is "svnpubsub"d, so that means that all you need to do as a release engineer is check in the release artifacts into the appropriate svn in the right place. Release distribution is covered in full in the "after the vote" section on the "how to release" page.
It is essential that, after everything has updated, you remove the older version of the artifact from the svn repository. The older version will have been archived at http://archive.apache.org/dist/manifoldcf, so you can still provide a link to the older version if you like. Apache rules, however, forbid more than one version of package from being replicated to the mirror downloads.
