Go command
The go build -asan option now defaults to doing leak detection at
program exit.
This will report an error if memory allocated by C is not freed and is
not referenced by any other memory allocated by either C or Go.
These new error reports may be disabled by setting
ASAN_OPTIONS=detect_leaks=0 in the environment when running the
program.
The new work package pattern matches all packages in the work (formerly called main)
modules: either the single work module in module mode or the set of workspace modules
in workspace mode.
When the go command updates the go line in a go.mod or go.work file,
it no longer adds a toolchain line
specifying the command's current version.

Vet
The go vet command includes new analyzers:
- waitgroup, which reports misplaced calls to [sync.WaitGroup.Add]; and
- hostport,
which reports uses of
fmt.Sprintf("%s:%d", host, port)to construct addresses for [net.Dial], as these will not work with IPv6; instead it suggests using [net.JoinHostPort].
