Much is rebooted, though it is a continuation. However, Superman is a mess. Prime Earth/New 52 Superman died just before Rebirth, and New Earth Superman (who had been plucked from the timestream during Convergence) took his place. Meanwhile, Prime Earth Lois was Superwoman briefly before she also died (at the opening stages of Rebirth), allowing for New Earth Lois to take her spot. Then some stuff with Mxyzptlk happened and I stopped bothering to get things straight.

Short version: current Superman never had a relation with Wonder Woman.

Wonder Woman, meanwhile, is also reset completely. All of the Azz/Chiang run as well as the Finch stuff turned out to be "lies", though the precise meaning of that hasn't been explained. Her entire demigod origin is thrown out and reverted back to her old made-of-clay origin.
