We serve you a podcast about the new Java version every six months.
Our regular guest, Simon Ritter, Deputy CTO of Azul, is known on social media as "speakjava." He is part of the OpenJDK vulnerability group, JCP executive committee, and expert group for the Java SE specification request so that he can share a lot of inside information with us.
In this episode, we are joined by Hanno Embregts, a Java Developer by day and musician by night. He publishes a post on Foojay with all the details of every new Java release and prepared a long description of all the new features included in Java 24.
Let's see what this new release brings us...
