I have made an f20 branch of spin-kickstarts. New changes should generally be applied to master and cherry-picked backed to f20 from now until the f20 release. (f20 and master have different repos active and doing a merge between master and f20 will break this, so don't do that.)
I also have made post branch package builds for f20 and rawhide.
I am not sure when nightlies will switch to using the f20 branch instead of master, but probably pretty soon.
