After releasing it to developers, Apple is now rolling out the latest iOS 15 beta for public beta testers. Apple refers to this as iOS 15 public beta 3 and it includes a handful of notable changes, such as Safari design changes, new Music widgets and more. Users interested in signing up for Apple's public beta testing programme can do so via Apple's website, 9To5Google reported. Apple's new software version won't be complete until the fall, at which point it will be released to the general public. Testers should still expect performance and stability issues when running the iOS 15 public beta on primary devices for the time being.
