Do 5e clerics of an evil bent have many options regarding undead? Are there other abilities said cleric could gain to have a more favorable relationship with undead (that they may have themselves made), say if they serve Velsharoon, Kiaranselee, or another God of Undeath? Perhaps they have another option for Domains that is not in the PHB? Are they expected to do this with spells, instead?
I see that "negative energy" is different, now, and that it, and undead, seem to have a new, different relationship, so how do evil clerics now associate with the undead? Can they bolster their minions, and defend them from the turning powers of their holy counterparts?
