+#v7.17.0
+
+## Client
+
+* Fixed a race condition on metrics in transport [#397](https://github.com/elastic/go-elasticsearch/pull/397), thanks @mainliufeng !
+* The client will now return an error if a required arguments is passed as a nil value. [#201](https://github.com/elastic/go-elasticsearch/issues/201)
+* API is compatible with Elasticsearch 7.17.0
+
+#v8.0.0-alpha
+
+## Client
+
+### Elastic Transport
+* This is the first release using the all new `elastictransport` which now lives in the [elastic-transport-go](https://github.com/elastic/elastic-transport-go/) repository. The goal is to allow for reuse between this and future Go clients.
+### API
+* Changed the `Body` parameter for `BulkIndexerItem` in favor of `io.ReadSeeker` to lower memory consumption when using the `esutil.BulkIndexer`.
+* Replaced the `Config` option `RetryOnTimeout` in favor of a new `RetryOnError` function which allows to dynamically chose what error should be retried."
+
+#v7.16.0
+
+# Client
+* Adds versioning and routing options to the `BulkIndexer`. Thanks to @mehran-prs and @munkyboy !
+
+* Adds CA fingerprinting.  You can configure the client to only trust certificates that are signed by a specific CA certificate (CA certificate pinning) by providing a ca_fingerprint option. This will verify that the fingerprint of the CA certificate that has signed the certificate of the server matches the supplied value:
+```go
+elasticsearch.NewClient(Config{
+Addresses:              []string{\"https://elastic:changeme@localhost:9200\"},
+CertificateFingerprint: \"A6FB224A4386...\"
+})
+```

+#v7.14.0
+
+# Client
+Starting in v7.14.0 the client performs a required product check before the first API call is executed. This product check allows the client to establish that it’s communicating with a supported Elasticsearch cluster.
+
+The product check requires a single HTTP request to the `info` API. In most cases this request will succeed quickly and then no further product check HTTP requests will be sent.
