Last week, I moved from the JBoss EAP product sustaining team to the awesome Quarkus team!!! Specifically to the Java Operator SDK project and the associated github.com/quarkiverse/... extension! And yes, I wasn't on the Quarkus team until now :)

#Java 23 will be forked today, so features are set in stone! 2 made it to finalization: * default GenZGC * Markdown in JavaDoc String templates are out, a big chunk of `Unsafe` got deprecated for removal, and 8 (!) previews evolved. More on all that in the latest Inside Java Newscast.

Join me this week at InfosharePL to learn what potential issues you can find in your apps when you dive head-first into virtual threads!

We’re officially open! 🎉 github.com/commonhaus/f...
