@@ -12,10 +12,12 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 - Media preview proxy (requires `ffmpeg` and `ImageMagick` to be installed and media proxy to be enabled; see `:media_preview_proxy` config for more details).
 - Pleroma API: Importing the mutes users from CSV files.
 - Experimental websocket-based federation between Pleroma instances.
+- Support for local-only statuses
 - Support pagination of blocks and mutes
 - App metrics: ability to restrict access to specified IP whitelist.
 - Configuration: Add `:instance, autofollowing_nicknames` setting to provide a way to make accounts automatically follow new users that register on the local Pleroma instance.

 ### Changed
 
 - **Breaking** Requires `libmagic` (or `file`) to guess file types.

 - `visibility`: string, besides standard MastoAPI values (`direct`, `private`, `unlisted` or `public`) it can be used to address a List by setting it to `list:LIST_ID`.
 - `expires_in`: The number of seconds the posted activity should expire in. When a posted activity expires it will be deleted from the server, and a delete request for it will be federated. This needs to be longer than an hour.
 - `in_reply_to_conversation_id`: Will reply to a given conversation, addressing only the people who are part of the recipient set of that conversation. Sets the visibility to `direct`.
+- `local_only`: boolean, if set to `true` the post won't be federated.
