Go lang

https://go.dev/ ↗

Go is a high-level, general-purpose programming language that is statically typed and compiled. It is known for the simplicity of its syntax and the efficiency of development that it enables through the inclusion of a large standard library supplying many needs for common projects.

go1.23.0 (released 2024-08-13)

Introduction to Go 1.23

The latest Go release, version 1.23, arrives six months after Go 1.22. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before.

Changes to the language

The “range” clause in a “for-range” loop now accepts iterator functions of the following types

func(func() bool)
func(func(K) bool)
func(func(K, V) bool)

as range expressions. Calls of the iterator argument function produce the iteration values for the “for-range” loop. For details see the iter package documentation, the language spec, and the Range over Function Types blog post. For motivation see the 2022 “range-over-func” discussion.

Go 1.23 includes preview support for generic type aliases. Building the toolchain with GOEXPERIMENT=aliastypeparams enables this feature within a package. (Using generic alias types across package boundaries is not yet supported.)

Tools

Telemetry

Starting in Go 1.23, the Go toolchain can collect usage and breakage statistics that help the Go team understand how the Go toolchain is

go1.22.0 (released 2024-02-06)

Introduction to Go 1.22

The latest Go release, version 1.22, arrives six months after Go 1.21. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before.

Changes to the language

Go 1.22 makes two changes to “for” loops.

  • Previously, the variables declared by a “for” loop were created once and updated by each iteration. In Go 1.22, each iteration of the loop creates new variables, to avoid accidental sharing bugs. The transition support tooling described in the proposal continues to work in the same way it did in Go 1.21.
  • “For” loops may now range over integers. For example: package main import "fmt" func main() { for i := range 10 { fmt.Println(10 - i) } fmt.Println("go1.22 has lift-off!") } See the spec for details.

Go 1.22 includes a preview of a language change we are considering for a future version of Go: range-over-function iterators. Building with GOEXPERIMENT=rangefunc enables this feature.

go1.21.0 (released 2023-08-08)

Introduction to Go 1.21

The latest Go release, version 1.21, arrives six months after Go 1.20. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility; in fact, Go 1.21 improves upon that promise. We expect almost all Go programs to continue to compile and run as before.

Go 1.21 introduces a small change to the numbering of releases. In the past, we used Go 1. N to refer to both the overall Go language version and release family as well as the first release in that family. Starting in Go 1.21, the first release is now Go 1. N.0. Today we are releasing both the Go 1.21 language and its initial implementation, the Go 1.21.0 release. These notes refer to “Go 1.21”; tools like go version will report “ go1.21.0 ” (until you upgrade to Go 1.21.1). See “ Go versions ” in the “Go Toolchains” documentation for details about the new version numbering.

Changes to the language

Go 1.21 adds three new built-ins to the language.

  • The new functions min and max compute the smallest (or largest, for max) value of a fixed number of given arguments. See the language spec for details.
  • The new function clear deletes all elements from a map or zeroes all elements of a slice.
