Trivia

 * The blog post for this update includes an image comparing the prior redstone mechanics to the changed mechanics. Previously, the before mechanics were labeled as1.15.2 mechanics, despite the presence of a target block, which was introduced later than 1.15.2. The image was later changed to correct this.
