Dev:Updating extensions for iOS 8

Let's collect knowledge like we did with Updating extensions for iOS 7 - paste in your notes and share what you've learned, and somebody else will organize it later. :) If you want to collaborate over IRC, see IRC for how to connect to #theos and #iphonedev.

Put stuff here!

 * iOS 8.0 Headers and another set of SpringBoard headers (made with two different class dumping tools).


 * The package  seems to not be working. An alternative - also as listed on TheiPhoneWiki.


 * In things like SBStarkBanner* classes, Stark is the codename for the blur-heavy UI since iOS 7
