- the mail window's send tab takes typing again: the subject, body and money boxes were taking no input while the recipient box swallowed every key, and a sent letter clears its subject and item icon instead of putting them straight back (2145)
- seven events fire the way the reference does: UNIT_DYNAMIC_FLAGS fires at all, swapping two identical stacks between bank slots fires PLAYERBANKSLOTS_CHANGED twice, the pet sheet's training points repaint, and ITEM_LOCK_CHANGED loses its invented arguments (2140)
- nine widget methods 1.12 addons probe for are in: ShaguTweaks stops recolouring textures the reference leaves alone, pfUI and _Nameplates stop raising on a tooltip's GetAnchorType, and 63 AceEvent addons get RegisterAllEvents (2142)
- six post-1.12 methods leave the widget surface (SetSize, SetShown, HasFocus, SetFormattedText and two tooltip verbs), so an addon reaching for a later client's API finds what a real 1.12 client gives it (2142, 2146)
