About this episode

The episode discusses the significant changes from Java 21 to 25 and the importance of upgrading to the latest Long-Term Support versions.

Every six months, we get a new version of Java. Java 26 is just around the corner and will be released soon. But most companies stick to LTS (Long-Term Support) versions, which are maintained and receive security updates for many more years. Versions 8, 11, 17, 21, and 25 are such LTS versions. Hopefully, most of your systems are already on the latest versions and you are not stuck on 8 or earlier. As a reminder, 8 was released in 2014, so much has changed since then.If you are doubting moving from 21 to 25, or even from an earlier version to the latest LTS, this podcast is for you! Together with Jakob Jenkov, we discussed the most important changes, and this episode includes a few quotes from interviews recorded at conferences last year.
