If you’re still using AdWords Editor 10.6 or older, it’s time to update. Why? Because AdWords will stop supporting older version of the Editor by June 30th.
From July 1st, only AdWords Editor 11 or higher will be supported. v11 was the most significant update to AdWords Editor since the tool was first released. Not only was the visual design reworked, but the user interface also became faster while new features were added and older ones enhanced.
