Hi all,
I've just merged https://gerrit.wikimedia.org/r/#/c/91500/, which changes the names of all of the OAuth special pages from MWOAuth to just OAuth. That means starting Thursday[0], any OAuth consumers will need to use Special:OAuth/initiate instead of MWOAuth, etc.
I don't anticipate us doing many breaking changes in the OAuth exchange. Since we currently only have 1 approved (non-demo/test) application, we felt it was better to do this now, instead of waiting and having to coordinate with more developers.
