+### Removed
+
+- **Breaking:** `Pleroma.Workers.Cron.StatsWorker` setting from Oban `:crontab` (moved to a simpler implementation).
+- **Breaking:** `Pleroma.Workers.Cron.ClearOauthTokenWorker` setting from Oban `:crontab` (moved to scheduled jobs).
+- **Breaking:** `Pleroma.Workers.Cron.PurgeExpiredActivitiesWorker` setting from Oban `:crontab` (moved to scheduled jobs).
+- Removed `:managed_config` option. In practice, it was accidentally removed with 2.0.0 release when frontends were
+switched to a new configuration mechanism, however it was not officially removed until now.
+
+### Fixed
+- Allow sending out emails again.
+
+## [2.1.2] - 2020-09-17
+
+### Security
+
+- Fix most MRF rules either crashing or not being applied to objects passed into the Common Pipeline (ChatMessage, Question, Answer, Audio, Event).
+
+### Fixed
+
+- Welcome Chat messages preventing user registration with MRF Simple Policy applied to the local instance.
+- Mastodon API: the public timeline returning an error when the `reply_visibility` parameter is set to `self` for an unauthenticated user.
+- Mastodon Streaming API: Handler crashes on authentication failures, resulting in error logs.
+- Mastodon Streaming API: Error logs on client pings.
+- Rich media: Log spam on failures. Now the error is only logged once per attempt.
+
+### Changed
+
+- Rich Media: A HEAD request is now done to the url, to ensure it has the appropriate content type and size before proceeding with a GET.
+
+### Upgrade notes
+
+1. Restart Pleroma
+
+## [2.1.1] - 2020-09-08
+
+### Security
+- Fix possible DoS in Mastodon API user search due to an error in match clauses, leading to an infinite recursion and subsequent OOM with certain inputs.
+- Fix metadata leak for accounts and statuses on private instances.
+- Fix possible DoS in Admin API search using an atom leak vulnerability. Authentication with admin rights was required to exploit.
+
+### Changed
+
+- **Breaking:** The metadata providers RelMe and Feed are no longer configurable. RelMe should always be activated and Feed only provides a <link> header tag for the actual RSS/Atom feed when the instance is public.
+- Improved error message when cmake is not available at build stage.
+
+### Added
+- Rich media failure tracking (along with `:failure_backoff` option).
