In which go version, the NotifyContext will be released?

golang/go/blob/3298300ddf45a0792b4d8ea5e05f0fbceec4c9f9/src/os/signal/signal.go#L277


// The stop function unregisters the signal behavior, which, like signal.Reset,
// may restore the default behavior for a given signal. For example, the default
// behavior of a Go program receiving os.Interrupt is to exit. Calling
// NotifyContext(parent, os.Interrupt) will change the behavior to cancel
// the returned context. Future interrupts received will not trigger the default
// (exit) behavior until the returned stop function is called.
//
// The stop function releases resources associated with it, so code should
// call stop as soon as the operations running in this Context complete and
// signals no longer need to be diverted to the context.
func NotifyContext(parent context.Context, signals ...os.Signal) (ctx context.Context, stop context.CancelFunc) {
	ctx, cancel := context.WithCancel(parent)
	c := &signalCtx{
		Context: ctx,
		cancel:  cancel,
		signals: signals,
	}
	c.ch = make(chan os.Signal, 1)
	Notify(c.ch, c.signals...)
	if ctx.Err() == nil {
		go func() {

In the next release, Go 1.16: https://tip.golang.org/doc/go1.16#os/signal

You usually can find this out by seeing tip.golang.org release notes, checking the issues on the GitHub tracker, or the commit that introduced the change on Gerrit (example: https://go-review.googlesource.com/c/go/+/219640).
