Ay, there is - testing is always good, even if we’re no where near beta. And even if it’s not for devs, the community needs testing to see what are the changes and new features. And it’s a good way to pass the time, if you’re on a holiday 
We had a testing with the previous images in January and I’ll set up a new thread and table for testing these new images too today, so we can collect observations to a more usable form. Any bugs should be reported to the mailing list.
