We'll have to figure out what is going on with the tests here.

I fixed the github CI tests in my last commit. Here is the link of the run in my repo

@vparpoil so it looks like we have to drop support form Meteor 1?

[vparpoil]

I indeed dropped the testing with Meteor 1. Since v2 was published in January 2021, I don't see the benefits of keeping those tests. What would be the arguments in favor of keeping tests for Meteor 1 ?

[StorytellerCZ]

Since v0.7 is for Meteor 3, I will fix the merge conflicts and if tests pass, then we are good for merge.

Fixed conflicts (hopefully), we'll see if the tests pass.
