Evad3rs team has released a new version of evasi0n7 1.0.3 today. It not only fixes the bugs which were causing the continuous boot loop on iPad mini Retina but also supports iOS 7.1 beta jailbreak. 
It is really surprising why the team included the support for iOS 7.1 jailbreak in it. Probably Apple already knows about the existing exploits which are used during the development of Evasi0n7 and the Cupertino company can block these exploits in next public iOS 7.1 build. So it looks like the Evad3rs team decided to support the beta release too for those developers who are eligible to install it.
This new version also includes the official Cydia store now. If you are already running a jailbroken device using Evasi0n7 1.0.2, you don’t need to re-jailbreak. Simply install the official Cydia build. This release is mainly for new jailbreakers and for those who are facing any boot loop and stuck at Apple logo issues on previous jailbreak.
People already running evasi0n7 1.0.2 on their devices do not have to update. http://t.co/lWu8tbs1oP software updates are for new installs — pod2g (@pod2g) January 11, 2014
