With iOS 10 on the horizon, it was expected that the recently released iOS 9.3.3 would be the last public release of iOS 9 before the next big software update.

But it turns out Apple had one more waiting in the wings, just in case. The company has officially released iOS 9.3.4 to the public, for the iPad and iPhone. It’s meant as a security update mainly, and there aren’t any major changes to the software, especially for the end user. The main focus is behind-the-scenes tweaks and improvements.

Apple will break down what the new software brings to the table right here. It has also been discovered that with the release of iOS 9.3.4, the Pangu iOS 9.3.3 jailbreak has been patched.

The update is available now.
