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?

Vector API preview status and value-class support are separate pieces of work. The API doesn’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.
There is no confirmed timeline yet. The most reliable source will be updates from the engineers working on the Vector API, so it’s best to follow the official OpenJDK development discussions rather than rely on guesses.
JDK 28 is possible, but that’s only speculation at this point. If it doesn’t happen there, a later release such as JDK 29 would be more realistic; there hasn’t been an official commitment.
