- MFR policy to set global expiration for all local Create activities
- OGP rich media parser merged with TwitterCard
- Configuration: `:instance, rewrite_policy` moved to `:mrf, policies`, `:instance, :mrf_transparency` moved to `:mrf, :transparency`, `:instance, :mrf_transparency_exclusions` moved to `:mrf, :transparency_exclusions`. Old config namespace is deprecated.
- Configuration: `:media_proxy, whitelist` format changed to host with scheme (e.g. `http://example.com` instead of `example.com`). Domain format is deprecated.
