DraStic

Which is latest version of Drastic Beta.
My drastic is only r2.2.1.2a(store version)
I have opted in for beta few months ago and was wondering if there is a beta version?

PS:My phone is galaxy grand duos(non rooted) running android 4.2.2(jelly bean)

Yup, there's one alright. Lordus released it not too long ago, and it addresses issues with several games along with a few other fixes.
