[Ifeffit] artemis split off source

A trivial question perhaps... I understand that the Artemis source is being split into a development version and a stable version. For those (like me) who like to live on the bleeding edge, where will the various sources reside? In particular, will the update_horae script upgrade to the latest development version (or perhaps there should be a switch for using the development version so it can't be executed by accident)?
