 ## [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: `: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.

 # Static Directory
 
-Static frontend files are shipped in `priv/static/` and tracked by version control in this repository. If you want to overwrite or update these without the possibility of merge conflicts, you can write your custom versions to `instance/static/`.
+Static frontend files are shipped with pleroma. If you want to overwrite or update these without problems during upgrades, you can write your custom versions to the static directory.
 
+You can find the location of the static directory in the [configuration](../cheatsheet/#instance).
+
+```elixir tab="OTP"

 ```
 
-For example, edit `instance/static/instance/panel.html` .

 Alternatively, you can overwrite this value in your configuration to use a different static instance directory.
 
-This document is written assuming `instance/static/`.
+This document is written using `$static_dir` as the value of the `config :pleroma, :instance, static_dir` setting.
