@ -156,6 +156,7 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
- Mastodon API: `pleroma.thread_muted` to the Status entity
- Mastodon API: Mark the direct conversation as read for the author when they send a new direct message
- Mastodon API, streaming: Add `pleroma.direct_conversation_id` to the `conversation` stream event payload.
- Mastodon API: Add `pleroma.unread_count` to the Marker entity
- Admin API: Render whole status in grouped reports
- Mastodon API: User timelines will now respect blocks, unless you are getting the user timeline of somebody you blocked (which would be empty otherwise).
- Mastodon API: Favoriting / Repeating a post multiple times will now return the identical response every time. Before, executing that action twice would return an error ("already favorited") on the second try.
