Go 1.11 has reached [end of support](/appengine/docs/standard/lifecycle/runtime-lifecycle#end_of_support) on January 30, 2024. Your\n existing Go 1.11 applications will continue to run and receive traffic. However,\n App Engine might block re-deployment of applications that use runtimes\n [after their end of support date](/appengine/docs/standard/lifecycle/support-schedule#go).\n To migrate to the latest supported version of Go, see\n [Migrate from Go 1.11 to the latest Go runtime](/appengine/migration-center/standard/migrate-to-second-gen/go-differences).\n\n- **Go second-generation runtimes (after end of support)** : To upgrade to a\n [supported version of Go](/appengine/docs/standard/lifecycle/support-schedule#go),\n update the `app.yaml` file by specifying a version of Go that you\n want your app to run. For example:\n\n runtime: go\u003cvar translate=\"no\"\u003eVERSION\u003c/var\u003e\n\n Where \u003cvar translate=\"no\"\u003eVERSION\u003c/var\u003e is the Go `MAJOR` and `MINOR` version numbers.\n For example, to use the latest Go version, Go 1.25,\n specify `125`.\n For more information, see the\n [Go runtime overview](/appengine/docs/standard/go/runtime)."]]
