Comment (by Samuel Cupp):

The CarpetX thorns are also in the GRHayLET repo, but require CarpetX to compile. They are

GRHayLET/GRHayLIDX
GRHayLET/GRHayLHDX

GRHayLET/IllinoisGRMHDX is still in a separate branch being debugged, and I will update when it is merged or if it won’t make it in time for the release.
