No, those were in the original versions. The fix was as described there: extended endings. The whole problem with the original is that the endings were so abrupt and you got no payoff for all the time spent with the crew and the universe. It's like they forgot they had to tell anything more than Shepard's immediate story somehow.

The Extended Cut endings basically showed what happens elsewhere in the galaxy and with the crewmates. And the DLC where you hang out with your crew before the final mission really helped even things out as well.

But it was always a three button choice. That wasn't a post-release fix.
