+## unreleased-patch - ???
+
+### Added
+- Rich media failure tracking (along with `:failure_backoff` option)
+
+### Fixed
+- Mastodon API: Search parameter `following` now correctly returns the followings rather than the followers
+- Mastodon API: Timelines hanging for (`number of posts with links * rich media timeout`) in the worst case.
+  Reduced to just rich media timeout.
+- Password resets no longer processed for deactivated accounts
+
 ## [2.1.0] - 2020-08-28
