> Hey Folks,
>
> The Grizzly Team is happy to announce the release of Grizzly 2.3.30!
>
> IMPORTANT: This is the first release where we feel the HTTP/2
> implementation
> is of proper beta quality. I will be following up to the announcement
> with
> details on how to enable HTTP/2, the configuration options, and how to
> leverage HTTP/2 push. As we still consider this beta, there may be
> API changes
> that could occur between now and when we feel it's solid.
>
> Issues resolved in this release: [1].
>
> The artifacts are available on both maven.java.net and central (there
> may be some delay before they are visible).
>
> Thanks to everyone who provided feedback and/or patches for this release!
>
> As usual, if there are additional suggestions on how to improve
> Grizzly going forward,
> or if a problem is discovered, please let us know via one or more of
> the suggestions
> on our contribution info page [2].
>
> Thanks!
