Pangu iOS 7.1.1 jailbreak was launched this week with the idea of offering users iOS 7.1.1 possibility of jailbreak own devices, but it seems to be compatible including with iOS 8. It was normal for this compatibility to exist since chances are that the exploits used for iOS 7.1.1 to be found in iOS beta 8 2, Apple going to close them until the release of the real version iOS 8.
Until then, the program developer geeksn0w, which does tethered jailbreak pe iOS 7.1 for iPhone 4, announced as it develops iOS 8 Pangu jailbreak. Unfortunately, the solution needs a document in which the hackers from pangu explain how they made this jailbreak solution, but also their agreement to release a version compatible with iOS 8, so we will have to wait until it is available.
I will return with additional details about the development process as they become available.
