GridEnhanced is Grid but specifically maintained for 1.12. I changed the name so there is no confusion as to which version grid you're running. It is based on the original Grid backport that is available for 1.12. This is a beta and I wouldn't recommend using this for hardcore progression raiding until it's better tested.
