Sorry, we can't really provide a release date but you're welcome to use that beta version in the meantime if you'd like. You don't need to wait.
Yes, exactly. And if it's used in a site/product/app for which a fee is collected from MULTIPLE users, that'd require the special commercial license that comes with "Business Green" memberships. ? Hopefully you'll find that the membership more than pays for itself very quickly.
Good luck with the project, @coolDev!
