What's happening with vector displacement 2.79b?

pretty quick question. I use the vector displacement node in order to add greebling to models. The latest version of 2.79b doesn’t have that node, which seems to be why sheepit render farm is returning “flat” non displaced models.

Does anyone know if I should just wait for an update? Or if there is a way to do displacement without the vector displacement node?

Thanks guys, appreciate any advice!
