I just upgraded to ELK 6 and updated my Logstash mapping template to the default one shipped with Logstash 6.

When I use this the Elasticsearch deprecation log show me this warning:

> [2018-02-27T09:40:46,871][WARN][o.e.d.i.m.MapperService] [_default_] mapping is deprecated since it is not useful anymore now that indexes cannot have more than one type

My question: Why is the new default Logstash mapping template using deprecated stuff?
