- Deprecated `User.Info` embedded schema (fields moved to `User`)
- Store status data inside Flag activity
- Deprecated (reorganized as `UserRelationship` entity) User fields with user AP IDs (`blocks`, `mutes`, `muted_reblogs`, `muted_notifications`, `subscribers`).
- Rate limiter is now disabled for localhost/socket (unless remoteip plug is enabled)
