With iOS 26 officially launched, Apple is moving forward with iOS 26.1. Apple just released the first beta version of the first major update to iOS 26 for developer beta testers.
Apple released iOS 26 on September 15, bringing the Liquid Glass redesign to the iPhone. We’re also starting to see third-party apps adopt Liquid Glass design now that iOS 26 is the current software version.
The build version for today’s iOS 26.1 beta is 23B5044l, up from 23A341 in the shipping version of iOS 26 on iPhone 17 and 23A345 for iPhone 17 Pro and iPhone 17 Pro Max.
We’ll update our coverage with any changes discovered in iOS 26.1 beta as soon as we have it running on our devices.
