The TaiG team announced a new version of the TaiG jailbreak tool just days before the launch of iOS 8.4. Now iPhone, iPad and iPod touch users running iOS 8.1.3-8.3 can jailbreak in a few easy steps. Of course, there are usually caveats for early adopters and TaiG 2.0.0 is no different.
UPDATE: TaiG has been updated to 2.2.0. This version jailbreaks iOS 8.4, is more stable and fixes several issues. Follow the instructions below to jailbreak iOS 8.4 on Windows.
Cydia Substrate has now been updated for full iOS 8.3 compatibility thanks to @saurik. Anyone who went ahead and already used TaiG 2.0.0 to jailbreak their devices does not have to re-jailbreak. Click here for instructions to update to TaiG 2.1.2.
MAC UPDATE: TaiG for Mac is here! For complete instructions on jailbreaking iOS 8.4 with TaiG on OS X click here.The initial release is only available on Windows, however Mac users can sucessfully jailbreak using a virtual machine. In any case, TaiG will likely follow up with an OS X release.
