- 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 Pleromas 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`.
* `quarantined_instances`: List of ActivityPub instances where private(DMs, followers-only) activities will not be send.
* `public`: Makes the client API in authenticated mode-only except for user-profiles. Useful for disabling the Local Timeline and The Whole Known Network. Note that there is a dependent setting restricting or allowing unauthenticated access to specific resources, see `restrict_unauthenticated` for more details.
* `quarantined_instances`: List of ActivityPub instances where private (DMs, followers-only) activities will not be send.
* `managed_config`: Whenether the config for pleroma-fe is configured in [:frontend_configurations](#frontend_configurations) or in ``static/config.json``.

Note: when `:instance, :public` is set to `false`, all `:restrict_unauthenticated` items be effectively set to `true` by default. 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`.
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).
