Milk-producing animals now regenerate reserves of milk in small amounts over time, and the milking process is now an auto-repeating process rather than a single action with an extremely long cooldown. This should make things much more convenient schedule-wise. The animals can also build up more milk than they previously provided, if you miss a day. If the animal is starving or suffering low morale, it will stop producing milk.
This also boils down to the process taking more time and energy, but also providing overall significantly more experience and practice for the Animal Husbandry skill than it did before.
