MuscleNerd confirmed the jailbreak over Twitter; however, he warns that you should probably wait a couple days before attempting.

“Looks like TaiG just released a jailbreak for 8.1.1 (and 8.0,8.1,8.2beta). Best to wait a few days just in case”

TaiG was part of the controversial iOS 7 jailbreak from the Evad3rs. The jaibreak included the TaiG ‘app store’ for cracked apps by default in China.
