 ### Single Table Inheritance deprecation
 
-`Single Table Inheritance` has been supported until the 6.x series of this gem. With this feature,
-settings on a parent model could be inherited by a child model leading to different model documents being indexed
-into the same Elasticsearch index. This feature depended on the ability to set a `type` for a document in Elasticsearch.
-The Elasticsearch team has deprecated support for `types`, as is described [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html)
-This gem will also remove support for types and Single Table Inheritance in version 7.0 as it encourages an anti-pattern. 
-Please save different model documents in separate indices or implement an artificial `type` field manually in each 
-document.
