Appveyor seems to still use Go 1.13?
But I guess we can just remove Appveyor, as we now have Windows on GHA?

Yes, makes sense to me. Less to maintain!

[thaJeztah]

I guess we could (should?) add macOS as well

[thaJeztah]

LGTM, thanks!

I'm assuming AppVeyor will disappear after this, but we could probably do a test PR after this to see if it stops complaining (or if changes to the repo settings are needed)

[AkihiroSuda]

Appveyor is failing for the master: https://ci.appveyor.com/project/sirupsen/logrus/builds/52271891

@thaJeztah Could you update the repo setting?

[thaJeztah]

😢 unfortunately I don't have access to settings; perhaps @sirupsen is able to (or to grant access). If possible, I also would not mind having @AkihiroSuda as co-maintainer.

Alternatively, we could add a stub AppVeyor config as a temporary workaround
