Yes this Google apps were updated a short time ago but if the update it’s good we don’t mind. It seems that Google isn’t done with Google Docs, Sheets and Slides. Before the begining of 2015, Google is updating their apps with some pretty useful new features.
These updates was released on the Google Play Store yesterday, and you will find new line spacing options for Docs, Sheets with scrollbars for quicker navigation and Slides updated with insert/move/resize/rotate for text boxes/shapes/lines. They have also added better accessibility options and ended with some bugs.
According to Google, all of their apps are now more Office files friendly. You can either download all of the apps for free on Google Play, or wait for the updates to hit your devices.
