Format changed for production logger?

[kotyara85]

Hey there,
Using this zap go.uber.org/zap@1.26
It looks like something did get change recently as production logger stopped returning logs in json format, but instead it does it in debug or dev mode

	zp, _ := zap.NewProduction()
	defer zp.Sync()

	zp.Info("OK", zap.String("OK", "OK"))

Generatest this output:

1.710310542583383e+09	info	main.go:15	OK	{"OK": "OK"}

Any input is appreciated

Ok, looks like upgrading to 1.27 solved the problem
