Chapter 6. Changes in Go Toolset

Go Toolset has been updated from version 1.17 to 1.18.4 on RHEL 7, RHEL 8, and RHEL 9.

Notable changes include:

The introduction of generics while maintaining backwards compatibility with earlier versions of Go.
A new fuzzing library .
New debug/buildinfo and net/netip packages.
The go get tool no longer builds or installs packages. Now, it only handles dependencies in go.mod.
If the main module’s go.mod file specifies go 1.17 or higher, the go mod download command used without any additional arguments only downloads source code for the explicitly required modules in the main module’s go.mod file. To also download source code for transitive dependencies, use the go mod download all command.
The go mod vendor subcommand now supports a -o option to set the output directory.
The go mod tidy command now retains additional checksums in the go.sum file for modules whose source code is required to verify that only one module in the build list provides each imported package. This change is not conditioned on the Go version in the main module’s go.mod file.
