   HttpURLConnectionTelemetryClient was removed. *service-telemetry* is now using [*concept-fetch*](https://github.com/mozilla-mobile/android-components/tree/master/components/concept/fetch) which allows consumers to use a unified http client. There are two options available currently: [lib-fetch-httpurlconnection](https://github.com/mozilla-mobile/android-components/tree/master/components/lib/fetch-httpurlconnection) (Based on [HttpURLConnection](https://developer.android.com/reference/java/net/HttpURLConnection)) and [lib-fetch-okhttp](https://github.com/mozilla-mobile/android-components/tree/master/components/lib/fetch-okhttp) (Based on [OkHttp](https://github.com/square/okhttp)).
