Go command
Setting the GOROOT_FINAL environment variable no longer has an effect
(#62047).
Distributions that install the go command to a location other than
$GOROOT/bin/go should install a symlink instead of relocating
or copying the go binary.
The new go env -changed flag causes the command to print only
those settings whose effective value differs from the default value
that would be obtained in an empty environment with no prior uses of the -w flag.
The new go mod tidy -diff flag causes the command not to modify
the files but instead print the necessary changes as a unified diff.
It exits with a non-zero code if updates are needed.
The go list -m -json command now includes new Sum and GoModSum fields.
This is similar to the existing behavior of the go mod download -json command.
The new go telemetry command can be used to view and configure the telemetry collection
mode. Without arguments, it displays the current mode. With local, on, or off, it sets
the collection mode. go env now lists two values: the GOTELEMETRY value, which
contains the telemetry collection mode, and the GOTELEMETRYDIR value setting which contains
the directory telemetry data and configuration are written to.
Vet
The go vet subcommand now includes the
stdversion
analyzer, which flags references to symbols that are too new for the version
of Go in effect in the referring file. (The effective version is determined
by the go directive in the file's enclosing go.mod file, and
by any //go:build constraints
in the file.)
For example, it will report a diagnostic for a reference to the
reflect.TypeFor function (introduced in go1.22) from a file in a
module whose go.mod file specifies go 1.21.
Cgo
[cmd/cgo] supports the new -ldflags flag for passing flags to the C linker.
The go command uses it automatically, avoiding "argument list too long"
errors with a very large CGO_LDFLAGS.
Trace
The trace tool now better tolerates partially broken traces by attempting to
recover what trace data it can. This functionality is particularly helpful when
viewing a trace that was collected during a program crash, since the trace data
leading up to the crash will now be recoverable under most
circumstances.
