I added two new clothing variables, "hats" and "boots," and migrated over any characters who already had such things (like Emma), but we'll have to see how that turns out.
So, not sure if you're at all inclined to report bugs, and this isn't actually directly related to the quoted bit of the update post, but it is a clothing bug that has been around for a while.
Storm's Halloween costume has a Ring Necklace to match the rings on her arms and legs. However, in the part of the code defining her Halloween costume, it's labeled as "ring necklace" while ever other part of the code referencing it (which is to say, the code for changing what she's wearing and the code for displaying it), the piece is referenced as "rings". As such it does not show when she's changed into her Halloween costume, though you can manually tell her to put it on after. It also may be worth noting that "rings" is also the name in code for the accessory that she wears on her arms and legs, with them being kept distinct by which outfit slot they are equipped in.
Bug aside, splitting out boots and hats to their own slot is something I've felt has been needed for some time, so I'm glad to see that done.
