Go Version History and Migration Tips

Go ships a new minor release every six months, and almost every release adds something useful to write modern code. This lesson walks through the major releases from Go 1.11 onwards, explains what each one added, and shows how to plan a migration when your codebase is several versions behind. The focus is practical: which features are worth adopting first, what to change in go.mod, and how to keep a library compatible with older Go versions while still using newer compiler features.
