The updated Google Calender version doesn't seem to be in the Play Store yet - version 5.3.8-117343094 updated 20160317 doesn't have the Goals feature (20160413 13:30 CET). Does anyone have access and if so how?

The play store webpage in the browser says something else (Updated: April 6, 2016 Current Version: Varies with device), but if I install that one remotely through the web, it ends up being the same version. Perhaps it's because I'm still running Android 5
