Well, not everything changed. Obviously, Barry was still The Flash at the end

Yes, but not until later.
Just caught the finale. It was very exciting, and I can't believe it ended on a cliffhanger. But there are now a whole host of time problems.
If Eddie's suicide caused Eobard Thawne never to be born, which erased him from time, then everything that happened on the whole season should have been wiped clean, because it was ALL orchestrated by Thawne. But that didn't happen.
Lucy, you got some 'splainin' to do!
