IIRC, Daravae & ShikenNuggets each stepped down due to time constraints a month or two ago. I believe they both posted about it on twitter. R0main & starsmiley were promoted from content mod to full mod, the former around the time Elo took over, the latter quite recently. ShadowDraft also became a full mod around the time Elo took over. All the previous admins left with the ownership change as well.

Any other changes happened before I joined the site in August.
