OpenJDK Java 23 Released With ZGC Generational Mode By Default

OpenJDK 23 is now generally available as the reference implementation to Java 23.

OpenJDK 23 presents support for Markdown documentation comments, the generational mode of the Z Garbage Collector (ZGC) enabled by default, and many other improvements. The Generational ZGC should work better than the non-generational mode for most use-cases.

In preview form OpenJDK 23 brings primitive types within Patterns / instanceof / switch, the latest preview of the Class File API, the latest incubator on Java's Vector API, module import declarations, structured concurrency, and the latest on scoped values.
