The Java Platform Module System (JPMS) is a code-level structure, so it doesn’t change the fact that we package Java into JAR files. Ultimately, everything is still bundled together in JAR files.

Java 23, now generally available, includes previews of module import declarations, stream gatherers, structured concurrency, scoped values, and a class-file API. And much more.

A new zSeries module serves as a dedicated processor for Java applications and debuts in time for the 40th anniversary of the mainframe.
