- Mix task to list all users (`mix pleroma.user list`)
- Support for `X-Forwarded-For` and similar HTTP headers which used by reverse proxies to pass a real user IP address to the backend. Must not be enabled unless your instance is behind at least one reverse proxy (such as Nginx, Apache HTTPD or Varnish Cache).

- Support for custom Elixir modules (such as MRF policies)
