-in Rails:
+Before version 7.0.0 of the gem, the only supported setting was `:inheritance_enabled`. This setting has been deprecated
+and removed.

+### Single Table Inheritance deprecation
+
+`Single Table Inheritance` has been supported through the 6.x series of this gem. With this feature,
+elasticsearch settings (index mappings, etc) 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 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.
