> The language and related pattern changed so little that that book is still good? Pretty much yes, and TGPL/Effective Go are still very good resources to learn the language, if not still the best available. Probably the biggest changes since 2015 were constant stdlib improvements / extensions, and things like the context API becoming standardized across the ecosystem. Oh, and Go modules. Otherwise the language is pretty much unchanged.
