 - Configuration: `:media_proxy, whitelist` format changed to host with scheme (e.g. `http://example.com` instead of `example.com`). Domain format is deprecated.
 - **Breaking:** Configuration: `:instance, welcome_user_nickname` moved to `:welcome, :direct_message, :sender_nickname`, `:instance, :welcome_message` moved to `:welcome, :direct_message, :message`. Old config namespace is deprecated.
 - **Breaking:** LDAP: Fallback to local database authentication has been removed for security reasons and lack of a mechanism to ensure the passwords are synchronized when LDAP passwords are updated.
+- **Breaking** Changed defaults for `:restrict_unauthenticated` so that when `:instance, :public` is set to `false` then all `:restrict_unauthenticated` items be effectively set to `true`. If you'd like to allow unauthenticated access to specific API endpoints on a private instance, please explicitly set `:restrict_unauthenticated` to non-default value in `config/prod.secret.exs`.

 * `federation_incoming_replies_max_depth`: Max. depth of reply-to activities fetching on incoming federation, to prevent out-of-memory situations while fetching very long threads. If set to `nil`, threads of any depth will be fetched. Lower this value if you experience out-of-memory crashes.
 * `federation_reachability_timeout_days`: Timeout (in days) of each external federation target being unreachable prior to pausing federating to it.
 * `allow_relay`: Enable Pleroma’s Relay, which makes it possible to follow a whole instance.
-* `public`: Makes the client API in authenticated mode-only except for user-profiles. Useful for disabling the Local Timeline and The Whole Known Network. See also: `restrict_unauthenticated`.

 Note: setting `restrict_unauthenticated/timelines/local` to `true` has no practical sense if `restrict_unauthenticated/timelines/federated` is set to `false` (since local public activities will still be delivered to unauthenticated users as part of federated timeline).
