Java Development Kit (JDK) 21, due in September as the next long-term support release of Oracle’s standard Java implementation, now has 16 features officially proposed for it, with three more features added in recent days.

The latest proposals include previews of structured concurrency and scoped values and preparations to disallow the dynamic loading of agents. Other recently added features include a key encapsulation mechanism (KEM) API and deprecation of the 32-bit x86 Windows port. Three other features—a generational Shenandoah garbage collector, unnamed classes and instance main methods, and unnamed patterns and variables—also were added last month.
