From other questions in the help-forum, it seems not. But they are months old now. Things move fast in the JS world, so worth asking. I tried pnpm create next-app --example with-jest and naïvely upgrading React and React-dom to 19.0.0 (--latest) to no avail. Is there a less obvious solution or should we just wait and downgrade to React 18.2 in the meanwhile?
