 - Adds the `delay_on_retry` parameter, a value in milliseconds to wait between each failed connection, thanks [DinoPullerUqido](https://github.com/DinoPullerUqido)! [Pull Request](https://github.com/elastic/elasticsearch-ruby/pull/1521) and [backport](https://github.com/elastic/elasticsearch-ruby/pull/1523).
-- 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:
