Last time my P2V+ was updated was summer 2015 and last time I flew it was early November this year...indeed I regularly still fly it but not this last few weeks because of the weather. Mind you, since it is, essentially, an obsolete aircraft (discontinued shortly after dji launched the P3 range) it has not been supported by firmware updates. The good side to this is that since dji are ignoring the existence of the P2V+ and not updating with firmware, it isn't suffering from the latter issues surrounding updates and, indeed, the data collection thing.
BTW, I'll be retiring it soon. not because there's anything wrong with it, but because my batteries for it are now long in the tooth and I suspect there's not that many good cycles left in them...I can't get replacements.
