Did you take a vacation this holiday season? It appears Apple did. After the release of iOS 13.3.1 developer beta 1 (then public beta 1 one day later), iOS beta testing went silent for almost a full month. With 2019 now in the books, it seems Apple is back to work, as developers received iOS 13.3.1 beta 2 today, Tuesday, Jan. 14.
Apple seeded developers the second 13.3.1 beta at 1 p.m. EST (10 a.m. PST), 28 days after iOS 13.3.1 dev beta 1. "Developers" is a keyword here, as the update is exclusively for registered developers. If you're a public beta tester, you'll need to wait for Apple to seed 13.3.1 public beta 2, which we expect to drop at 4 p.m. EST (1 p.m. PST) today or 1 p.m. EST Monday.
So, what can you expect from 13.3.1's second beta? Thanks to Brandon Butch, we know that Apple included a buried toggle to enable or disable ultra-wide band (UWB) functionality found in the iPhone 11. Before 13.3.1, this option would use location services to check whether a given area supported UWB, with no option to disable it. Butch claims that this toggle was not there on dev beta 2's release day, which, if true, would mean Apple added it after the fact as an over-the-air update.
The first beta for 13.3.1 didn't add much to iOS, other than a bug fix for Screen Time. Apple admitted as much in its brief release notes, which read, "There are no release notes for this software update," and that's exactly the same as beta 2.
