iOS 8.1 brings bug fixes, speed improvements, and interface changes, but it also enables Continuity features such as Text Message Forwarding and Instant Hotspot, allowing iOS devices to better integrate with each other and Macs running OS X Yosemite. With iOS 8.1, Apple is opening access to its iCloud Photo Library beta – an iCloud service that stores all your photos from all your devices, in a single library that relays changes to every device. And last, iOS 8.1 marks the debut of Apple Pay, the company’s new payment service that rolls out in the US today.
I installed it on an iPhone 6 and an iPad 2 today and haven’t noticed any issues. Apple Pay looks to be the most notable and exciting feature, provided you have a supported card and the retailer supports NFC payments.
