Go is a programming language created by Google. This document discusses Go and its versioning. It introduces vgo, a new tool that aims to improve how Go packages are versioned and managed without GOPATH. Vgo uses Go modules stored in version control as the fundamental unit, allowing flexible versioning and avoiding conflicts. This could replace dependency management tools like dep while improving the development experience for the Go ecosystem.
