Magic Items on the BodyMany magic items need to be donned by a character who wants
to employ them or benefit from their abilities. It’s possible for
a creature with a humanoid-shaped body to wear as many as
15 magic items at the same time. However, each of those items
must be worn on (or over) a particular part of the body, known
as a “slot.”
A humanoid-shaped body can be decked out in magic gear
consisting of one item from each of the following groups,
keyed to which slot on the body the item is worn.

Not only did they add Shield as a slot, Pathfinder separated the head slot into 2 (Head and Headband), and the Chest slot into 2 (Chest and Body). So you can now wear magical armor and magical robes in Pathfinder, as well as a magical headband and magical helmet.
