Previously named the OS X Beta Program, it is now called the Apple Beta Software Program.
Apple is hoping to better squash software bugs by releasing test versions of iOS builds to members of the public program.
If you join the program, Apple does offer some advice:
Always back up your iOS device before installing beta software. To get a shipping release of iOS on your iPhone, iPad, or iPod touch, you can simply install the final version of the software you are testing when it appears in Software Update. If you would like to go back to a previously released version, you must first erase the beta software, then re-install the latest shipping version of iOS, and finally restore from your previously saved iTunes backup.
Just a few hours ago, Apple also released the third beta version of iOS 8.3 to registered developers. So far, there are a number of improvements. Along with support for wireless CarPlay, the software features new Siri languages, support for Google’s two-factor authentication, and more.
The program is widely expected to continue when Apple releases a beta version iOS 9 at WWDC in June.
I’m glad to see Apple expand the public beta program to iOS. While it’s not for everyone, hopefully this will help Apple’s software become even more stable before being released to all iOS device users.
