I am happy to announce the release of #netty 4.1.122.Final. Beside bug-fixing we also decided we will re-enable the usage of Unsafe by default while using Java24 , because the performance penalty is just too high without it for now. Check: netty.io/news/2025/06/03/4-1…

We are happy to announce the release of #netty 4.1.121.Final. We did a quick followup release as something went wrong during our release of 4.1.120.Final yesterday and so required a different GLIBC version as expected. See: netty.io/news/2025/04/24/4-1…

Norman continuing to kill it on the io_uring networking side. This is the way, Nettty will be something to point to as a reference implementation of how it should be done.

I am proud to share that #netty was selected by @SpotifyEng to receive their #OSS fund this year. This wouldn't have been possible without all the help of our community. Thanks a lot to everyone and of course @SpotifyEng itself: engineering.atspotify.com/20…
