 ## [2.0.0] - 2019-03-08
 ### Security
 - Mastodon API: Fix being able to request enourmous amount of statuses in timelines leading to DoS. Now limited to 40 per request.

 - Mastodon API: User timelines will now respect blocks, unless you are getting the user timeline of somebody you blocked (which would be empty otherwise).
 - Mastodon API: Favoriting / Repeating a post multiple times will now return the identical response every time. Before, executing that action twice would return an error ("already favorited") on the second try.
 - Mastodon API: Limit timeline requests to 3 per timeline per 500ms per user/ip by default.
+- Admin API: `PATCH /api/pleroma/admin/users/:nickname/credentials` and `GET /api/pleroma/admin/users/:nickname/credentials`
