Wouldn't it be better to just have two branches: "NONE" (stable version) and "Experimental Versions"? "NONE" updates when a new stable version is released, "Experimental Versions" updates when a new experimental build is released (just like the enable experimental versions function in the standalone game does (did?)).
With the current "each version as a branch" you'll always need to update your settings once a new build is there, that's too complicated.
