+
+Starting with verion 7.0, embedded HTML or special symbols like `<` and `>` are
+no longer escaped by default when publishing events.

+
+Starting with version 7.0, Filebeat stores the registry in a sub-directory.

+If Filebeat finds an old registry file at the configured location, it will
+automatically migrate the registry file to the new format.
+
+The settings `filebeat.registry_flush` and `filebeat.registry_file_permission`
+have been renamed to `filebeat.registry.flush` and
+`filebeat.registry.file_permission`.

+release moved most ILM settings from the `output.elasticsearch.ilm` namespace to
+the `setup.ilm` namespace.
