I think AWS Lambda supports Go 1.x. Does GCF plan to stick to Go 1.11.x or broaden support to other Go versions in the future? What will happen to 1.11.x support when 1.12 comes out?
For long-term support of various languages, see the GCP deprecation policy: https://cloud.google.com/terms/deprecation
Especially this sentence: "excluding [...] support for a programming language version that is no longer publicly supported by, or receiving security updates from, the organization maintaining that programming language"
So, that means we're committed to supporting the two most recent major version releases of Go, as per the Go release policy: https://github.com/golang/go/wiki/Go-Release-Cycle#release-m...
Disclaimer: I work on GCP and used to work on Go language releases.
