Being a 5.1.1 build, there are several new things. For example, heads-up notifications are much less annoying. You also get device protection features (Samsung calls this anti-theft). The OTA comes with the usual collection of fixes and smaller feature additions too. We'll dig in and see if there's anything else of note to report.
