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
syslogd to /var/log/syslogseems 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
- The term 'Display Identifier' has been removed from SpringBoard. Methods that used the term usually have a 'Bundle Identifier' equivalent; e.g. -[SBApplicationController applicationWithDisplayIdentifier:] and -[SBApplication displayIdentifier] are now -[SBApplicationController applicationWithBundleIdentifier] and -[SBApplication bundleIdentifier]
