 - **Breaking:** removed `with_move` parameter from notifications timeline.
 
 ### Added
+- ActivityPub: Added support for existing AP ids for instances migrated from Mastodon.
+- Instance: Add `background_image` to configuration and `/api/v1/instance`
 - Instance: Extend `/api/v1/instance` with Pleroma-specific information.
 - NodeInfo: `pleroma:api/v1/notifications:include_types_filter` to the `features` list.
 - NodeInfo: `pleroma_emoji_reactions` to the `features` list.
 - Configuration: `:restrict_unauthenticated` setting, restrict access for unauthenticated users to timelines (public and federate), user profiles and statuses.
+- Configuration: Add `:database_config_whitelist` setting to whitelist settings which can be configured from AdminFE.
+- Configuration: `filename_display_max_length` option to set filename truncate limit, if filename display enabled (0 = no limit).
 - New HTTP adapter [gun](https://github.com/ninenines/gun). Gun adapter requires minimum OTP version of 22.2 otherwise Pleroma won’t start. For hackney OTP update is not required.
 - Mix task to create trusted OAuth App.
 - Notifications: Added `follow_request` notification type.
 - Added `:reject_deletes` group to SimplePolicy
+- MRF (`EmojiStealPolicy`): New MRF Policy which allows to automatically download emojis from remote instances

+# Optimizing your PostgreSQL performance
+
+Pleroma performance depends to a large extent on good database performance. The default PostgreSQL settings are mostly fine, but often you can get better performance by changing a few settings.
+
+You can use [PGTune](https://pgtune.leopard.in.ua) to get recommendations for your setup. If you do, set the "Number of Connections" field to 20, as Pleroma will only use 10 concurrent connections anyway. If you don't, it will give you advice that might even hurt your performance.
+
+We also recommend not using the "Network Storage" option.
+
+## Example configurations
+
+Here are some configuration suggestions for PostgreSQL 10+.
+
+### 1GB RAM, 1 CPU
+```
+shared_buffers = 256MB
+effective_cache_size = 768MB
+maintenance_work_mem = 64MB
