 ### Compatibility
 
-The library is compatible with all Elasticsearch versions since 5.x, and you should use the same major version of the Elasticsearch instance that you are using.
+Language clients are forward compatible; meaning that clients support communicating with greater minor versions of Elasticsearch.
+Elastic language clients are also backwards compatible with lesser supported minor Elasticsearch versions.

+===== Verify connection to Elasticsearch https://github.com/elastic/elasticsearch-js/pull/1487[#1487]
+
+The client will verify if it's working with a supported release of Elasticsearch.
+Elastic language clients are guaranteed to be able to communicate with Elasticsearch or Elastic solutions running on the same major version and greater or equal minor version.
+
+Language clients are forward compatible; meaning that clients support communicating with greater minor versions of Elasticsearch. Elastic language clients are not guaranteed to be backwards compatible.

+===== Add api compatibility header support https://github.com/elastic/elasticsearch-js/pull/1478[#1478]

-and improves the child creation performances by ~12%.
-* The client no longer inherits from the EventEmitter class, but instead has an internal event emitter and exposes

+=== Automatic product check
+
+Since v7.14.0, the client performs a required product check before the first call.

+be sent to the server as part of the request pipeline before the main API call is sent.
+In most cases, this will succeed during the very first API call that the client sends.
+Once the product check completes, no further product check HTTP requests are sent for
