Surbhi bansal for audit (changes as per 12th edition)

Hi Folks!!

I am preparing to appear for november 2015 final examination. 

For Advanced Audit and Professional Ethics, I have been referring to Surbhi Bansal (11th edition). Could anyone please help me out with the changes as per the new edition (12th) ? Does anyone have a soft copy of the changes or any link to it. 

Thanking in Anticipation!!
