- Due to Nickelodeon shortening the series' screentime, Book Three episodes were twenty-two minutes long, down from twenty-three minutes as in previous books.
- On June 8, 2014, episodes three through six of Book Three were accidentally leaked on the Mexican Nickelodeon website, MundoNick.
- The leaked episodes prompted the production team to release an official trailer for the third book on June 11, earlier than originally planned.
- On August 7, 2014, the tenth episode of Book Three was leaked as well.
- Book Three: Change ends with the Avatar substantially wounded, much like Book Two: Earth of the original series. It also parallels Book Three: Fire in the fact that both end with a ceremony and the imprisonment of the primary antagonists.
- This was the first book in the franchise in which neither Katara nor Aang appeared.
- The book both starts and ends two weeks after the resolution of a major event: the defeat of UnaVaatu and the defeat and imprisonment of Zaheer, respectively.
- This is the only book of The Legend of Korra in which the final battle did not take place in Republic City.
