Apple today seeded the third beta of iOS 10.3.3 to developers. We see this two weeks after the last seed of iOS 10.3.3. Right now, we’re unsure what’s new in this version. It does, however, include a few new wallpapers on the iPad.
To get this version developers with the beta testing profile installed can go to Settings > General > Software updates > iOS 10.3.3. If you don’t have the testing profile installed yet, you can download it from the developer center.
