Today is the day, yet another beta release. iOS 8 beta 4 is out and available through the developer portal or OTA. It clocks in at just 300MB, but requires 3GB of space to install. Why, I have no idea. I found the last beta to be incredibly buggy. With each successive release, I hope this gets remotely stable. Downloading OTA now. Fingers crossed. As for what's new, list them as you find them!
