Hi Guys, There is ES 8.0.0 released, but I cannot find transport-netty4-client for 8.0.0: [https://repo1.maven.org/maven2/org/elasticsearch/plugin/transport-netty4-client/](https://repo1.maven.org/maven2/org/elasticsearch/plugin/transport-netty4-client/) Is it an oversight or maybe, for some reason, the lib won't be released anymore? Thanks, ---

The transport client has been deprecated since 7.0 was released a couple of years ago. From 8.0 onwards you will need to use the HTTP client. > **[Transport Client | Java Transport Client (deprecated) \[7.17\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/transport-client.html)** ---

TBH I'm interested in HttpServerTransport implementation. Is there sth I can use instead of Netty4HttpServerTransport class from the transport-netty4-client? ---

`HttpServerTransport` and its implementations are part of the Elasticsearch server, they're not intended to be used separately and aren't released as independent packages. ---

But they were published. Now they are not. There was no info that the implementation is deprecated (or at least that it will be removed from public packages). ---

Unfortunately things that aren't in the public API docs aren't something you can rely on existing in later versions. I don't think implementation details like `HttpServerTransport` are in any such docs. Moreover the whole client has been documented as deprecated for several years. ---
