 - Admin API: Return `total` when querying for reports
 - Mastodon API: Return `pleroma.direct_conversation_id` when creating a direct message (`POST /api/v1/statuses`)
 - Admin API: Return link alongside with token on password reset
+- MRF (Simple Policy): Also use `:accept`/`:reject` on the actors rather than only their activities
 
 ### Fixed
 - Mastodon API: Fix private and direct statuses not being filtered out from the public timeline for an authenticated user (`GET /api/v1/timelines/public`)
