Eclipse Vert.x 3.9.1 released!

We are extremely pleased to announce that the Eclipse Vert.x version 3.9.1 has been released.

Among all bug fixes you can find in 3.9.1 this enhancement

JDK 8 HTTP/2 support

Previously using the Jetty ALPN agent or netty-tcnative was required to use HTTP/2 on JDK 8.

TLS ALPN support has been back-ported to JDK 8 recently and Vert.x has been upgraded to support it which means now you can have HTTP/2 on JDK 8 out of the box. You need to most recent version of OpenJDK 8 or Oracle JDK 8.
