Here is the full change log for the update:
Version 0.3 of this package fixes the issue where, on 32-bit devices (iPod 5, iPhone 4S/5, iPad 2, iPad Mini 1) a specific background process (launchd) would sometimes “spinâ€, burning CPU and battery, or even heating up.
This package has been pulled by Saurik for the following reasons. Quoting Saurik on /r/jailbreak:
Some users on 64-bit devices are reporting mild to serious issues with this package. According to the Pangu team, they have changed almost nothing on 64-bit, and have not seen the issue themselves in their testing. We have pulled the package anyway, and the people at Pangu are working on doing a more detailed analysis of the issue.
It looks like we will have to wait..
