Welcome to another episode of the Foojay Podcast! In this episode, we’re talking about Java 26, released on March 17 in the year 26. Again, right on schedule with Java’s six-month release cadence.

Now, Java 26 is not a Long Term Support (LTS) release; that was Java 25. But don’t let that fool you into thinking there’s nothing interesting here. This release brings ten JDK Enhancement Proposals (JEPs). They cover everything from performance improvements to long-overdue cleanups. Of those ten JEPS, five are new features, and we also get five preview/incubator features.
