if I'm understanding this right servers now default to allowing anyone to add emoji and the ilk, and this permission was retroactively applied to existing servers. I'm seeing a few servers I'm in letting me add emoji now, and reports that it's happened to servers which are not under the 50 member count the update mentions. check your permissions!
the best part is discord actually seems to have done this change weeks ago but most people are only seeing the changelog today.
