We use unpatched langauge toolchains/runtimes for GCF and second-generation GAE. That means a drastically reduced time to release for new language versions. (Maintaining patched runtimes was a significant burden to making new versions of Go available on GAE.) For long-term support of various languages, see the GCP deprecation policy: https://cloud.google.com/terms/deprecation 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-maintenance https://github.com/golang/go/wiki/Go-Release-Cycle#release-m... Disclaimer: I work on GCP and used to work on Go language releases.
