@JimBobSquarePants Thanks for your lightning fast response! Do you have an estimate for when you will be able to push a new release with the fix?

[JimBobSquarePants]

Not a problem! We plan a proper release this week but in the interim there are nightlies you can try. The feed is linked from our readme.
