Java 26 Is Here, And With It a Solid Foundation for the Future

Tue, 17 Mar 2026 07:00:00 +0000

Java 26 is here! Six months ago, we welcomed Java 25 into our hearts, which means it’s time for another fresh helping of Java features. This time, the set of features is a bit smaller compared to some of the previous releases, which can only mean one thing: the focus for this release was to provide a solid foundation for something big to be released soon™️! My hope is that the first JEPs out of Project Valhalla will be announced later this year. That hope is fueled by some of Java 26’s changes as they feel like appropriate preparation steps for the first Valhalla features (this is especially true for JEPs 500 and 529 ).

Here's Java 25, Ready to Perform to the Limit

Tue, 16 Sep 2025 06:05:00 +0000

It’s been six months since Java 24 was released, so it’s time for a fresh set of new Java features.

And the feature that immediately grabs the attention this time is stable values, taking Java’s support of immutability to the next level. Also, Java’s focus on improving performance intensifies, as more JEPs emerge from Project Leyden. On top of that, the Java Flight Recorder is now more equipped than ever to tackle performance issues!

In the second part of our JCON interviews, recorded at the conference in May, we focuses on general evolutions within the Java world and how they influence how we write code and develop applications. We take a look back at the history of Java, discuss new features in the latest release, how Java evolves with OpenJDK projects and JEPS, how Java is used in education, and much more…

Java 24 Rolls Out Today! Find Out Why It's Aptly Named

Tue, 18 Mar 2025 07:36:39 +0000

Java 24 rolls out today! It’s been six months since Java 23 was released, so it’s time for another helping of new features. And this particular release of Java is aptly named, because it contains exactly 24 JEPs. Coincidence? I think not. 🙂

{#more-115735}

Java 24 brings a diverse set of features, delivering performance improvements like compact object headers, garbage collection optimizations and the first JEP to come out of Project Leyden. On top of that, various security features related to the quantum computing field were added, and a solution to virtual thread pinning is now available!

As developers, we like to automate the boring parts of our job. This automation includes the source control system, build pipelines, and code analysis tools.
