As usual before a Java release, I'm listing all the new performance features in the upcoming release, this time for Java 22 (I have done this every 6 months prior to each new release, you can track back to the previous February and August newsletters if you want to see what's new performance-wise in any particular release). Each time I give the new features, the performance benefits from each feature, and how to use the feature.

Java 22 has one significant new feature, the Foreign Function and Memory API. This is finally released after more than 10 years since first being started as project panama. It's perhaps a strength of the JDK 6 monthly release cadence that a project can continue for 10 years, and get steadily improved from multiple rounds of feedback. The corresponding weakness is that these larger projects seem to take much longer than expected to deliver - panama taking more than 10 years, virtual threads took more than 6 years and even then it's not pre-emptive and has noticeable limitations.

Now on to the details of those Java 22 changes, including the options you have available to use them. And of course the tips from this month's articles, as ever are extracted into this month's tips page.
