Google’s Go (golang) language has reached version 1.22, bringing changes to for loops including a resolution to problem that risked the accidental sharing of loop variables.
Released February 6, Go 1.22 can be downloaded and installed from go.dev. Release notes for Go 1.22 can be found on the project website.
With Go 1.22, the Go team has resolved what has been called the for loop “gotcha,” leading to accidental sharing of loop variables. In Go 1.22, each iteration of the loop builds new variables to avoid accidental sharing bugs. In a second change, for loops in Go can now range over integers.
