Has Go changed much since its creation?

Question

I've also been recently learning about Ember.js. It's not really an apples-to-apples comparison since Ember.js is a framework while Go is a language. Ember.js is relatively new and I've found out that some tutorials written as recently as this year are already out of date.

For example, is this blog from 2010, https://blog.golang.org/gos-declaration-syntax , about Go's declaration syntax still valid?

Answer 1

Go hasn't changed much such its first public release. The blog is good.

Go has compatibility guarantees.

Introduction

The release of Go version 1 (March 2012), Go 1 for short, is a major milestone in the development of the language. Go 1 is a stable platform for the growth of programs and projects written in Go.

Go 1 defines two things: first, the specification of the language; and second, the specification of a set of core APIs, the "standard packages" of the Go library. The Go 1 release includes their implementation in the form of two compiler suites (gc and gccgo), and the core libraries themselves.

It is intended that programs written to the Go 1 specification will continue to compile and run correctly, unchanged, over the lifetime of that specification. At some indefinite point, a Go 2 specification may arise, but until that time, Go programs that work today should continue to work even as future "point" releases of Go 1 arise (Go 1.1, Go 1.2, etc.).

Compatibility is at the source level. Binary compatibility for compiled packages is not guaranteed between releases. After a point release, Go source will need to be recompiled to link against the new release.

The APIs may grow, acquiring new packages and features, but not in a way that breaks existing Go 1 code.
