Go 1.21 will be released most likely on 1/07/2023 (tomorrow)
It’s six month after the release of Go 1.20, meaning we finally can see some new features of the Go language. During that time there were six minor security releases, just like in a clock for every month because Go is systematic.
The new release comes with some fascinating upgrades I have to share with you even though I’ve caught a flu.
Go 1.21 comes with these features:
Min And Max Functions
Go 1.21 offers now min and max functions like every other standard library except Kotlin that offers coerceAtMost and coerceAtLeast.

Clear Function
Clearing a map, or slice in Go was troublesome at least. With Golang 1.21 you can just use the new clear function that works as you’d expect it to.
