 ### Added
 - NodeInfo: `pleroma:api/v1/notifications:include_types_filter` to the `features` list.
 - Configuration: `:restrict_unauthenticated` setting, restrict access for unauthenticated users to timelines (public and federate), user profiles and statuses.
+- New HTTP adapter [gun](https://github.com/ninenines/gun). Gun adapter requires minimum OTP version of 22.2 otherwise Pleroma won’t start. For hackney OTP update is not required.
 - Configuration: `:extensions/:output_relationships_in_statuses_by_default` option (if `false`, disables the output of account/pleroma/relationship for statuses and notifications by default, breaking the compatibility with older PleromaFE versions).
