When will the Vector API support value classes and become a preview feature?

Does anyone know when the Vector API is expected to support value classes? Once that work is complete, would the API be ready to ship as a preview feature in a future JDK release, possibly JDK 28 or later?

JDK 28 is possible, but thatโ€™s only speculation at this point. If it doesnโ€™t happen there, a later release such as JDK 29 would be more realistic; there hasnโ€™t been an official commitment.

There is no confirmed timeline yet. The most reliable source will be updates from the engineers working on the Vector API, so itโ€™s best to follow the official OpenJDK development discussions rather than rely on guesses.

Vector API preview status and value-class support are separate pieces of work. The API doesnโ€™t necessarily need to wait for value classes before becoming a preview feature, so the release schedule may depend on other implementation and design milestones.
