-## [unreleased]
+## Unreleased
### Changed
+
+- **Breaking** Requires `libmagic` (or `file`) to guess file types.
+- Renamed `:await_up_timeout` in `:connections_pool` namespace to `:connect_timeout`, old name is deprecated.
+- Renamed `:timeout` in `pools` namespace to `:recv_timeout`, old name is deprecated.
+
+### 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).
+
+### Changed
+- Minimum lifetime for ephmeral activities changed to 10 minutes and made configurable (`:min_lifetime` option).
+
+## [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).
+
+### Fixed
+- Default HTTP adapter not respecting pool setting, leading to possible OOM.
+- Fixed uploading webp images when the Exiftool Upload Filter is enabled by skipping them
+- 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.
+- Mastodon API: Cards being wrong for preview statuses due to cache key collision.
+- Password resets no longer processed for deactivated accounts.
+- Favicon scraper raising exceptions on URLs longer than 255 characters.
+
+## [2.1.0] - 2020-08-28
+
+### Changed
+
+- **Breaking:** The default descriptions on uploads are now empty. The old behavior (filename as default) can be configured, see the cheat sheet.
+- **Breaking:** Added the ObjectAgePolicy to the default set of MRFs. This will delist and strip the follower collection of any message received that is older than 7 days. This will stop users from seeing very old messages in the timelines. The messages can still be viewed on the user's page and in conversations. They also still trigger notifications.
+- **Breaking:** Elixir >=1.9 is now required (was >= 1.8)
+- **Breaking:** Configuration: `:auto_linker, :opts` moved to `:pleroma, Pleroma.Formatter`. Old config namespace is deprecated.
+- **Breaking:** Configuration: `:instance, welcome_user_nickname` moved to `:welcome, :direct_message, :sender_nickname`, `:instance, :welcome_message` moved to `:welcome, :direct_message, :message`. Old config namespace is deprecated.
+- **Breaking:** LDAP: Fallback to local database authentication has been removed for security reasons and lack of a mechanism to ensure the passwords are synchronized when LDAP passwords are updated.
+- **Breaking** Changed defaults for `:restrict_unauthenticated` so that when `:instance, :public` is set to `false` then all `:restrict_unauthenticated` items be effectively set to `true`. If you'd like to allow unauthenticated access to specific API endpoints on a private instance, please explicitly set `:restrict_unauthenticated` to non-default value in `config/prod.secret.exs`.
+- In Conversations, return only direct messages as `last_status`
+- Using the `only_media` filter on timelines will now exclude reblog media
- MFR policy to set global expiration for all local Create activities
- OGP rich media parser merged with TwitterCard
-- **Breaking** Requires `libmagic` (or `file`) to guess file types.
+- Configuration: `:instance, rewrite_policy` moved to `:mrf, policies`, `:instance, :mrf_transparency` moved to `:mrf, :transparency`, `:instance, :mrf_transparency_exclusions` moved to `:mrf, :transparency_exclusions`. Old config namespace is deprecated.
+- Configuration: `:media_proxy, whitelist` format changed to host with scheme (e.g. `http://example.com` instead of `example.com`). Domain format is deprecated.
