Upgrading Your Go: A Developer’s Guide to Seamlessly Updating Your Go Version

If you’ve been writing Go (Golang) for any length of time, you already know and love its legendary backward compatibility. The Go team’s promise that code written for Go 1.1 will still compile and run cleanly on the latest versions is one of the language’s greatest superpowers.
