it seems that bitaddress version (1.6) dates from 11 Jan 2014..don't exist in 2012 
Bitaddress 1.6 was introduced on 29 July 2012. Nothing was introduced on 11 Jan 2014.The releases that you see on github was just the date it was published. The actual versions were actually published pretty early: https://github.com/pointbiz/bitaddress.org/commits/master?after=72aefc03e0d150c52780294927d95262b711f602+139&branch=master
