Golang 1.20: What is new?
What is new in Golang 1.20? Compared to the 1.19 release there are no major changes to the language but rather additions to the runtime, libraries and toolchain. The are lot of features but there eight I want to call out:
■ Go subcommands -C to change directory
■ Skip pattern support for generate and test
■ Code coverage for running applications
■ vet incorrect times
■ Wrapping multiple errors
■ archive/tar and archive/zip security changes
■ context’s new WithCancelCause
■ time’s new layout constants and compare
