 ## [unreleased]
 
 ### Changed
+- **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.
 - In Conversations, return only direct messages as `last_status`

 - 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.
 - **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.
