Yeah- I've been preparing something for someone and can confirm that the database is up to date. As to why an updated version hasn't been yet released I can imagine 3 possibilities, all of which are probably wrong:
1). they've coded it as far as it can go (and it is really, really good in the current form); or
2). they have an updated new nifty version soon to be released which will not be free; or
3). As both Baidu an Alibaba have AV's that totally suck, one of these is in talks with WV for an acquisition (pocket change for them).
