The full change log reads:
1. Fix the issue that launchd may drain cpu on 32bit devices.
2. Fix Safari reloading bug and occasionally crash problem.
3. Optimize jailbreak process.
4. Restore function now support iPad Air2/iPad Mini3.
Obviously, if your jailbroken device is behaving as it should, you don’t have anything to do at this time. If you’re still experiencing issues, specifically those related to CPU usage and/or Safari, it might be a wise thing to head over to Cydia and update the untether package. As a last resort, you may have to consider restoring your device and using the latest version of Pangu to jailbreak again.
