I guess I'm lumping a lot of JDK20 stuff in there as well since most folks will hold off migrating until LTS releases arrive with features. But the combination of things like Record Patterns, Virtual Threads, Foreign Function and Memory API and the Vector API will add up to a very powerful set of features for building data focused applications.

Those features are in incubator/preview mode in Java 20. While they might be released with 21, they might as well not. So I wouldn't hold my breath, unless you can jump on preview features (and if you can, why even care about LTS).

yeah .... good point. I really hope at least some of them do because they will really make a big difference.
