I can work on this when I have some free time over the next couple of days. Thank you for creating such a plugin

I already had a PR for this a couple of days ago #3 and now that a non-beta API is published, we might just be able to move ahead with that one.

I'd rather not have duplicated work and that PR already looked promising at first glance so I think we are better off following that one rather than the migration guide.

should now work in 0.7.1
