Ok, it took a while but I’ve setup github actions and fixed the test suite for beta and canary.

It turns out I had @embroider/util pinned to an old version and that was the source of some of the failures. I’ve released a new patch version in which I allow that dependency to float.

Perhaps that fixes the problems some of you have experienced?

Sorry for neglecting this for so long, I’m super busy and try to concentrate my OS work on Fridays. Glad @csprocket777 found the issue.

I’m going to migrate to github actions to fix CI.
