Wikipedia And Linguistics

Did anybody else notice not too long ago a lot of the phonology charts in different articles were changed to have LABIAL, CORONAL, and DORSAL listed on them? I can't seem to find another one at a quick glance, so maybe it was just a coincidence or it has since changed back, but it seemed like a strange thing to do. Especially since other information was removed. So far though, it seems like it's all back to normal, so, unless one turns up, I'll be done on the issue. Oh those crazy wikipedians and their lightning fast changes.
