According to this article on the advantages vs disadvantages of Gerrit/Gitblit and the Diffusion/Differential combo we may switch to Phabricator's code workflow process. I was poking around a bit and it seems that Differential is nowhere to be found on Phabricator. The URL returns a 404 and it isn't listed in the launcher. So is Differential in a newer release of Phabricator than what we already have or is it disabled in an obscure way? From the existing workflow and this article we will want to go with Differential (pre-push) rather than Audit (which we have and have been testing and is post-push).
