If you haven't seen a proper change-log for a Google app, that is probably your chance. It is not visible on Google Play but you will find it in the app.
Some of the changes that come with version 4.2 include the possibility to share your custom reports as a link.
How to test:
- Navigate to the Dashboard tab.
- Tap on Create a report.
- Generate any report and tap on the 3 dots menu.
- Select the Share option.
Apart from this, a notable change was made to the search view which got smart suggestions.
