+- **Breaking:** Configuration: `:auto_linker, :opts` moved to `:pleroma, Pleroma.Formatter`. Old config namespace 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`.
