TaiG has updated their jailbreak tool to "2.2.0" which is now compatible with iOS 8.4 which was just released today.
Unfortunately, hours before, 25PP [a famous piracy based iOS team] decided to release their own tool that uses TaiG's exploits without their permission. Supposedly they have breached TaiG's files and the tool is not known to be safe. Stick with TaiG's tool for a clean install.
