In-app update with TestFlight on iOS

Question

My iPhone app has now entered into a beta phase. I am using TestFlight to send the app to the testers. Everything works great, I publish the link, they download the app, no problem with any certificate or anything (true story, lol).

My only problem is I have absolutely no idea on how to send in-app updates. I saw on the latest SDK version that it's available, but I can't figure out how to do it ! Right now, if I upload a new build, and select "update & notify", an email is sent. How can I send a notification to the users, directly through my app, that a new version is available ? Right now I'm starting to think that this is not possible (if so, my bad). But I really thought I could do it !

As always, any help/link/doc is always appreciated ! :)

You can force an upgrade.

Go into settings in the upper right corner and select the "gear" then choose "Area 51" (this is the new features area, still beta). From there you can select to turn on "Forced Upgrades":

If you enable force upgrades on a build. The next time users open your build and there is an update available they will be forced to install the build before continuing.
