Following the release of iOS 13.3.1 on January 28, Apple has stopped signing iOS 13.3, which means downgrading to that version of iOS is no longer possible.

iOS 13.3 was a major update that included Communication Limits for Screen Time, support for NFC, USB, and Lightning FIDO2-compliant security keys in Safari, and more.

Apple routinely stops signing older versions of software updates after new releases come out in order to encourage customers to keep their operating systems up to date.

iOS 13.3.1 is the current publicly available version of iOS, with the update introducing a toggle for the U1 Ultra Wideband chip in the newest iPhones along with various bug fixes and improvements.

Developers and public beta testers can also download iOS 13.4, an upcoming update that includes a new toolbar in the Mail app, iCloud Folder Sharing, new Memoji stickers, and more.

Any minute now Apple will activate the daily nag servers to notify all iOS users to install iOS 13 for us non-conformists. It's been quiet for a few weeks.
 
Just updated to 13.3.1. Seems to have broken my ability to connect to wifi. Already tried rebooting the iPhone - it sees the networks but tells me none have an internet connection, despite other devices connecting to the internet via the wifi networks just fine.

Edit: Seems to have resolved itself about 24 hours later. Probably an issue with the router, not the phone, given a reboot didn't fix it but the simple passage of time did.

No kidding. Talk about living inside the nanny state....as a power user and someone who does NOT YET want to update my IP8 (and knows full well the 'consequences' for not being currently patched) I'm so tired of Cupertino telling me what I should be doing.

I have had the same problem that started several updates ago. It will get on some WiFi but not all and other devices will work just find where it won’t. Has driven me crazy. Now I just got the 13.3.1 and I’ve got apps that won’t open. Tap em. They try to open. Then are like nope, never mind. At least four apps that I use on a daily basis are like this.
