Animal Shapes
Choose any number of willing creatures that you can see within range. Each target shape-shifts into a Large or smaller Beast of your choice that has a Challenge Rating of 4 or lower. You can choose a different form for each target. On later turns, you can take a Magic action to transform the targets again. A target's game statistics are replaced by the chosen Beast's statistics, but the target retains its creature type; Hit Points; Hit Point Dice; alignment; ability to communicate; and Intelligence, Wisdom, and Charisma scores. The target's actions are limited by the Beast form's anatomy, and it can't cast spells. The target's equipment melds into the new form, and the target can't use any of that equipment while in that form.
The target gains a number of Temporary Hit Points equal to the Beast form's Hit Points. The transformation lasts for the duration for each target, until the target has no Temporary Hit Points, or until the target leaves the form as a Bonus Action.

It also specifies a Magic action for re-transformation and limits actions by anatomy, whereas the 2014 version replaces stats and restricts speech and spellcasting.
