We added two more report types to the Overview and Messages dashboards.
In Overview, you can now view reports for users inactive in the last day, 7 days, and 30 days. Add an Uninstall field to the report to see which inactive users have uninstalled in the period after their last seen activity.
In Messages, the new A/B Tests report displays metrics for events related to your A/B Tests.
