Instead of the deepest-nested "Riding" entity being the bottom-most in the stack of riding entities, the entity at the root of the data is at the bottom of the stack. For example, the armor stand in the following command is at the bottom of the stack while the cow and pig are at the same depth:

Trivia

 * "This week’s snapshot brings you the ability to smash out of the window of a high tower building, fly past the bad guys who are all shooting you with surprisingly bad accuracy, swoop down and land flawlessly into a strategically placed boat and then paddle away at moderately high speeds with the stolen prize pig in the back." is a reference to all the things added in this snapshot.
 * "Ability to smash out of the window of a high tower building" may be a reference to End Cities on how they have purple stained glass and you may smash out of them to get out.
 * "Fly past the bad guys who are all shooting you with surprisingly bad accuracy" may be a reference to Shulkers on how their bullets move only in the X, Y and Z positions.
 * "Paddle away at moderately high speeds" is a reference to how both oars needs to be moved in order to move straight at moderately high speeds compared to previous versions.
 * "With a stolen prize pig in the back" is a reference to how the boats can now contain two entities.
