I was told a couple of days ago by the vendor for my new IPC-HFW4300S V2 that the 2014-06-21 build was the latest for V2. He indicated he had confirmed this with the manufacturer, and he could get no other firmware updates later than this to work on his own V2. I haven't had my camera long enough to know if settings change on there own as yours do. I am hoping an upgrade will fix a problem with the Event/Video/Motion/Setup screen which has an empty threshold graph that won't show any activity, even though motion events are triggered as expected. Anyone else able to get this graph to work with this firmware on a V2? Apologies if this was covered previously in this incredibly long thread.
