Apple today released iOS 26.1, the first major update to the iOS 26 operating system that came out in September, iOS 26.1 comes over a month after iOS 26 launched. iOS 26.1 is compatible with the iPhone 11 series and later, as well as the second-generation iPhone SE. The new software can be downloaded on eligible iPhones over-the-air by going to Settings > General > Software Update.
iOS 26 has progressively gotten better on my M2 iPad Pro. It was a stuttery mess during the betas.
