==== Features
[discrete]
===== Support for Elasticsearch `v7.14`
You can find all the API changes
https://www.elastic.co/guide/en/elasticsearch/reference/7.14/release-notes-7.14.0.html[here].
[discrete]
===== 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.
[discrete]
===== Add api compatibility header support https://github.com/elastic/elasticsearch-js/pull/1478[#1478]
If you configure the `ELASTIC_CLIENT_APIVERSIONING` to `true` the client will send a compatibility header
to allow you to use a 7.x client against a 8.x cluster. In this way it will be easier to migrate your code to a newer release of Elasticsearch.
[discrete]
===== Add support for bearer auth https://github.com/elastic/elasticsearch-js/pull/1488[#1488]
Bearer authentication, useful for https://www.elastic.co/guide/en/elasticsearch/reference/current/security-api-create-service-token.html[service account tokens].
Be aware that it does not handle automatic token refresh:
[source,js]
----
auth: {
bearer: 'token'
}

===== Bulk update improvements https://github.com/elastic/elasticsearch-js/pull/1428[#1428]
The final stats object will let you know how many `noop` operations happened.
Also, a new `.stats` getter has been added to allow you to read the stats before
the operation finishes.
[source,js]
----
const b = client.helpers.bulk({ ... })
...
console.log(b.stats)

===== Add warning log about nodejs version support https://github.com/elastic/elasticsearch-js/pull/1349[#1349]

while `7.12` will be the last one that supports Node.js v10. If you are using

recommend to upgrade to newer versions of Node.js as usng an EOL version will
expose you to securty risks.
