Golang 1.22: What is new?

What is new in Golang 1.22? Compared to the 1.21 release, the Go team added a new fix for a common "for" gotcha, new routing patterns, new standard library changes and more!. There are a lot of features, but there are six I want to call out: ■ Fix "for" the for gotcha when using goroutines ■ Support to iterate over integers when using "for" ■ First ever v2 in the standard library: "math/rand/v2" ■ Routing patterns support in "net/http.ServeMux" ■ Filesystem (FS) support in "net/http" ■ New "slices" Concat function ■ Examples: https://github.com/MarioCarrion/video... ■ Blog post: https://mariocarrion.com/2024/02/12/w... == Installing ■ Download: https://go.dev/dl/#go1.22.0 ■ Release notes: https://go.dev/doc/go1.22 ■ API changes: https://github.com/golang/go/issues/6... ■ "go install":   / 1755005673975218662   ■ MacOS Homebrew: https://github.com/Homebrew/homebrew-... == All Go/Golang Playlists ■ Software Architecture in Go/Golang:    • Software Architecture and System Design in...   ■ Building Microservices in Go/Golang:    • Building Microservices in Golang/Go   ■ Go/Golang Tools and Packages:    • Golang/Go Tools and Packages   ■ Learning Concurrency Patterns in Go/Golang:    • Learning Go/Golang Concurrency Patterns   ■ Learning Go/Golang :    • Learning Go/Golang   ■ Learning Relational Databases in Go/Golang:    • Learning Go/Golang: Relational Databases   ■ Testing in Go/Golang:    • Testing in Golang/Go   00:00 - Intro Golang 1.22 00:07 - How to install 00:19 - for gotcha fixed 01:23 - for to iterate over integers 01:52 - rand v2 package 03:20 - net/http.ServeMux routing patterns 05:28 - net/http FS support 06:51 - slices Concat 07:19 - Conclusion === Who am I?
