Apple has released iOS 11.1 beta 4 this morning, along with watchOS 4.1 beta 4 for developers.
This quick release comes four days after third betas were released for iOS 11.1, watchOS 4.1 and tvOS 11.1. In iOS 11.1 beta 3, Apple brought back Reachability for Plus-sized iPhone owners, while also reimplemented Haptic feedback for an incorrect passcode entry.
Apple stated earlier this week all of their betas have already been patched against the KRACK Wi-Fi WPA2 exploit.
No word on what’s new in these betas yet, but stay tuned for updates.
