JEP 429, Extent-Local Variables (Incubator), was promoted from its JEP Draft 8263012 to Candidate status. This incubating JEP, under the auspices of Project Loom, proposes to enable sharing of immutable data within and across threads. This is preferred to thread-local variables, especially when using large numbers of virtual threads.

InfoQ will follow up with a more detailed news story.

JDK 19

Build 35 of the JDK 19 early-access builds was made available this past week, featuring updates from Build 34 which include fixes to various issues. More details on this build may be found in the release notes.
