About amendments in SBR

Greetings Sir,

I am planning to give SBR in december examinations. One thing i want to ask about the text book. First thing i am not sure about how many amendments are here for this year in SBR. Actually i got a text book from one of my friend which is from Emile woolf International author which is applicable till june 2019. Now i wanna ask that do i need to buy latest book for december or this earlier edition would work?

Also for Practice i will buy the kit but i wanted to ask about the text book.
So kindly help me with the correct direction.
Thank you
