Content and features are slightly different. Feature-wise we're around the 16.1 mark, content-wise we're still gathering data to update our databases for 15.2 (devs please correct me if i'm wrong). There's an awful lot of data flying around that we could use to half-update some of our databases, but then they wouldn't coincide with other areas where we have data to publish for 16.2 or even the newer 17.1 data. The item and mob db can be updated to match kRO on the fly, but making sure that other systems and features work cohesively is what keeps us behind, because we can't simply push out updates for things that the emu isn't ready to handle.
