Go command

Cgo

Cgo currently refuses to compile calls to a C function which has multiple incompatible declarations. For instance, if f is declared as both void f(int) and void f(double), cgo will report an error instead of possibly generating an incorrect call sequence for f(0). New in this release is a better detector for this error condition when the incompatible declarations appear in different files. See #67699.

Vet

The new tests analyzer reports common mistakes in declarations of tests, fuzzers, benchmarks, and examples in test packages, such as malformed names, incorrect signatures, or examples that document non-existent identifiers. Some of these mistakes may cause tests not to run.

This analyzer is among the subset of analyzers that are run by go test.

GOCACHEPROG

The cmd/go internal binary and test caching mechanism can now be implemented by child processes implementing a JSON protocol between the cmd/go tool and the child process named by the GOCACHEPROG environment variable. This was previously behind a GOEXPERIMENT. For protocol details, see #59719.
