It's finally here. The Gold Master (GM) build of iOS 14 and iPadOS 14 is available for iPhone 11 Pro, iPhone XS Max, iPad Pro and more.

It's been one rollercoaster ride since iOS 14 and iPadOS 14 were announced back at WWDC 2020. We saw a ton of betas, and now we are finally at the GM build of iOS 14 and iPadOS 14, both. These are essentially the final builds of the software which will be released to everyone tomorrow. However, if you currently have the beta or public beta installed onto one of your compatible devices, then you can latch onto the GM release immediately.
