For the Minecraft Bedrock 1.20.60 changelog, it claims that steeds (horses, donkeys, and mules) will receive fall damage unless the world was made prior to 1.20.60.
Horses, Donkeys, and Mules now take fall damage when controlled by a player, except for worlds targeting base game versions before 1.20.60
It is either phrased wrong or implying worlds made prior are different. In my realm, made prior to the update, the intended damage effect is present. Is this intentional?
"Base game version" is a weird psycho backward compatibility thing for marketplace maps, it doesn't affect the average user's survival world: https://learn.microsoft.com/en-us/minecraft/creator/documents/basegameversioning?view=minecraft-bedrock-stable
