- the shift-hover item compare is gone: 1.12.1 compares only from the vendor and auction rows, and the plate those seat picks its side so it never slides back over its own tooltip (2210, 2207)
- UnitIsPlusMob is implemented, off the flag bit and not the creature rank, so an addon that calls it no longer raises (2209)
- a top-level frame named $parentX with a parent= attribute is published under that parent's name, so ClassIcons loads (2208)
- a parent= that resolves to nothing leaves the frame parentless and logs it, as the reference does, instead of falling back to the enclosing frame (2213)
