Recent updates believed not to have affected homebrew are:
System Menu 4.1 (JP only)
, updated HCCJ (Room Channel & Food Delivery Channel apparently) System Menu 3.5 (KR only). Updates are hard to tell due to the then-lack of Multiimpersonator, but are thought to include [[IOS52]], [[IOS254]], [[IOS40]], [[IOS41]], [[IOS43]], [[IOS45]], and [[IOS46]]. None of these do anything more than in 3.4.
