The conclusion of the original storyline conceived by Sugar when developing Steven Universe, the episode serves as the culmination of the story arcs developed over the course of the series, most notably the Crystal Gems' conflict with the Gem Homeworld and the healing of the monstrous corrupted Gems. It also features the debut of new designs for most of the main characters and several previously unseen fusions. In "Change Your Mind", Steven must reunite with the Crystal Gems and open the eyes of the three Diamonds to the dysfunctionality of their family dynamic.

Officially promoted under the alternative title "Steven Universe: Battle of Heart and Mind", the episode premiered on Cartoon Network on January 21, 2019. It received a viewership of 0.989 million people and was acclaimed by critics, with most praise going to its themes, scale, animation, writing, and voice performances, as well as White Diamond's treatment, characterization, and confrontation with Steven. Reviewers unanimously agreed that "Change Your Mind" felt like a crucial turning point for the series that could effectively serve as a series finale, with The Post stating "Steven Universe can never go back to how it was before."

The series was followed by the television film Steven Universe: The Movie (2019) and the epilogue limited series Steven Universe Future (2019–2020), both of which take place two years after the events of "Change Your Mind".
