After its review has concluded, JEP 464, Scoped Values (Second Preview), has been promoted from Proposed to Target to Targeted for JDK 22. Formerly known as Extent-Local Variables (Incubator), this JEP proposes to re-preview the API in JDK 22, without change, in order to gain additional experience and feedback from the previous round of preview, JEP 446, Scoped Values (Preview), delivered in JDK 21, and JEP 429, Scoped Values (Incubator), delivered in JDK 20. This feature enables sharing of immutable data within and across threads. This is preferred to thread-local variables, especially when using large numbers of virtual threads.
