I was too, so I popped into the #mephisto channel on freenode and technoweenie set me straight. The subversion trunk in mephisto will be the latest stable release (in this case 0.8) of his github repo.

But for an easy way to just download the 0.8 release, go here and then click on download and you’ll get a nice shiny tarball.

Thanks to the Mepisto team for making a great blogging app!
