I get the following error trying to build Pulumi v3.62.0 using go version go1.18.1 linux/amd64 (per CONTRIBUTING.md):

+ cd pkg
+ go install -ldflags '-X <http://github.com/pulumi/pulumi/pkg/v3/version.Version=0.1.0-alpha.1673497087+g4996550f|github.com/pulumi/pulumi/pkg/v3/version.Version=0.1.0-alpha.1673497087+g4996550f>' <http://github.com/pulumi/pulumi/pkg/v3/cmd/pulumi|github.com/pulumi/pulumi/pkg/v3/cmd/pulumi>

backend/filestate/backend.go:385:18: undefined: atomic.Int64
backend/filestate/backend.go:388:19: undefined: atomic.Int64

Has anyone run into this ?

sync/atomic

is go 1.19 only

Should that change be documented somewhere ?

if you file an issue to update the CONTRIBUTING.md we can fix it

Yeah, I was just filling out a bug report when you responded
