v1.2.0-M2

Reactor Netty 1.2.0-M2 is part of 2024.0.0-M2 Release Train.

This milestone adds HTTP/3 server support.

Enablement of the HTTP/3 server support:

• a dependency to netty-incubator-codec-http3 is specified
• the HTTP protocol is configured as HTTP3

The example below shows one simple configuration for the HttpServer:

public class Application {

	public static void main(String[] args) throws Exception {
		File certChainFile = new File("certificate chain file");
		File keyFile = new File("private key file");

		Http3SslContextSpec serverCtx = Http3SslContextSpec.forServer(keyFile, null, certChainFile);

		DisposableServer server =
				HttpServer.create()
				          .port(8080)
				          .protocol(HttpProtocol.HTTP3)
				          .secure(spec -> spec.sslContext(serverCtx))
				          .idleTimeout(Duration.ofSeconds(5))
				          .http3Settings(spec -> spec.maxData(10000000)
				                                     .maxStreamDataBidirectionalLocal(1000000)
				                                     .maxStreamDataBidirectionalRemote(1000000)
				                                     .maxStreamsBidirectional(100))
				          .handle((request, response) -> response.header("server", "reactor-netty")
				                                                 .sendString(Mono.just("hello")))
				          .bindNow();

		server.onDispose()
		      .block();
	}
}

Reactor Netty 1.2.0-M2 inherits all changes from the 1.0.x and 1.1.x branches at the point this release was cut.
