yes, I've updated the text to make it clearer.

I completely understand your frustration, John. We acknowledge that clearer communication on upgrade compatibility would have been helpful, and we’ll work to improve how we document these kinds of changes in future Developer Previews. While we can’t guarantee direct upgrades from early "L" builds to later preview versions, we’re looking into possible ways to mitigate this for future updates. Thanks for your feedback, and we truly appreciate your engagement!

Hi Andreas! We appreciate your enthusiasm! At this stage, the documentation is still in progress and will be updated as we finalize the release content.

If there are specific areas you're interested in testing, let us know, and we’ll do our best to provide some guidance.

Thanks for your patience!
