Go 1.11 has reached end of support
and will be deprecated
on January 31, 2026. After deprecation, you won't be able to deploy Go 1.11
applications, even if your organization previously used an organization policy to
re-enable deployments of legacy runtimes. Your existing Go
1.11 applications will continue to run and receive traffic after their
deprecation date. We
recommend that you migrate to the latest supported version of Go.
