Apple just rolled out iOS 26 beta 4, and these are some of the biggest changes you'll find if you have access to the latest developer beta.

Apple announced in June that the release of iOS 26 would first appear as developer betas as usual, with the first public beta set for July. When it reaches general release it will be on the 2025 releases, iPhone 17 series, as well the iPhone 16 series and plenty of much earlier models.

iOS 26 beta 4 just arrived, and it is likely the last developer beta that Apple will launch ahead of the expected public beta debut this month. That hasn't stopped Apple from making some fairly significant tweaks to the OS though. Liquid Glass, iOS 26's big new design language, has become more "liquid" again, after beta 3 tuned down the effect.
