Apologies in advance to MisterWoodhouse is this is spoiling a future technical update thread.
It seems that two new sections have been added to Special:Analytics. Recently, a section indicating new/returning users was added and now page views are broken down by Discussions v. Wiki. For my wiki, the new sections appeared today but maybe they appeared yesterday for some wikis? Yesterday my wiki's Special:Analytics had update issues and the view count wasn't showing at all.
Also, does anyone know of a wiki that has the active and top users sections? They appear to have been hanging around in the layout for a while; I believe since Special:Analytics was introduced. However, I have never heard/seen a wiki that actually as them.
