It appears a Chinese company called PP has stolen code from TAIG and has released a working version that supports jailbreaking iOS 8.4. Please note that this has been tested as working by users but we are still unsure how stable it is. If you have to be jailbroken this instant feel free to give it a go. I am thinking that I am going to wait a few days to make sure there is no malicious code involved. For more information check out the PP website. http://pro.25pp.com/ppghost
