Just under a week has passed since the seed of the second beta, Apple is now seeding iOS 9.1 beta 4 to developers on Wednesday. The new beta doesn't seem to have any major changes, most likely bug fixes and stability improvements. However for those out of the loop, iOS 9.1 brings features like iPad Pro accessory support and new emoji with Unicode 8.
Fortunately folks who just can't wait to start sending the new taco and burrito emoji, can download the public beta of iOS 9.1 at Apple's website. I'm currently running the iOS 9.1 public beta and it seems to be running flawlessly. The golden master and public builds of iOS 9.1 are expected to release at some point in October.
