Thank you for participating in the OS X Beta Program. For the first time ever, we are broadening the program to include the all-new iOS Beta. The feedback you have provided on the OS X Yosemite Beta continues to help us shape OS X, and we would like to offer you an invitation to the iOS 8.3 Beta.
The iOS 8.3 Beta is available for download from the new Apple Beta Software Program website. Try it out and submit your feedback. You can use the iOS 8.3 Beta while continuing to use the OS X Yosemite 10.10.3 Beta. And with the all-new Photos app for Mac and iCloud Photo Library, you can now access your entire library on all your devices.
