With In App Messaging, you can stay up to date with Xray new versions, features and other information, by receiving product and release related announcements.
Clicking on the snippets showing up on the bottom left side you are taken to that announcement detail, and by clicking on the floating button on the bottom right you can see the history of all received announcements.
You can chose to turn off In App Messaging selectively, or totally in the "Xray Notification Settings" page accessible from your user profile menu.
