Currently, I won't be supporting both the "public" stable and "development" branches at the same time from the Admin mod.

What you may wish to do is subscribe to my development version of the Admin mod, which is where I put ALL the latest changes when assessing new changes to SE. This includes the Development branch.
It may break from time to time however, as I push experimental changes to it first for testing.
