Java 21 Launch Event

Java 21 was released on September 19th, 2023! We celebrated that on the Java YouTube channel, where we hosted an 8-hour live stream covering the launch of Java 21 as well as some other announcements.

During the event we covered what's in this release, interviewed exciting guests like Chief Java Architect Mark Reinhold, Chief Java Language Architect Brian Goetz, and Timefold co-founder Geoffrey De Smet, and we had community segments featuring the Paris and Karlsruhe JUGs. Our lovely hosts Ana-Maria Mihalceanu, Billy Korando, and Nicolai Parlog led through the event.
