So, the big change is Divine Smite has been codified as an actual Paladin Spell. This opens up some fun, like using charging up Rings of Spell Storing with Smites. It also eliminates the additional ruling about how you can't cast a spell (especially a Smite spell) and use Divine Smite together in a much cleaner way. It also is now a target for counterspell, so that can be ... fun? I'm a Blue Mage, I cackled at that. Also Arcane Trickster Rogues can steal it for themselves.
