 ### Single Table Inheritance support
 
 Versions < 7.0.0 of this gem supported inheritance-- more specifically, `Single Table Inheritance`. 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)
-so this gem has also removed support as it encourages an anti-pattern. Please save different model documents in
-separate indices or implement an artificial `type` field manually in each document.

+This gem will also remove support for types and `Single Table Inheritance` in version 7.0 as it enables an anti-pattern.
+Please save different model documents in separate indices. If you want to use STI, you can include an artificial
+`type` field manually in each document and use it in other operations.
