Brand new MLP episodes are aired weekly in my heart. We're up to season 27 (And they're amazing!). Importantly, season 11 retroactively retcon'd out the school of friendship, student 6, creature equestria, etc. by treating it all as an alternate timeline in Twilight's premonition of what the future would be if she didn't travel to the human earth and eliminate Haber, his flunkies, certain writers, and a select number of Hasbro bigwigs. But, in the season finale she figured out a magic spell for it and carried out the task, thus saving Equestria.
