Differences between new and old syllabus for CCA 175?

I have already finished till Pyspark from old playlist and I am seeing that the people appearing exam in month of April are also getting questions as per old syllabus. I am in a dilemma of whether to start with new playlist as per revised syllabus or study with the old playlist.

Can someone point out the changes between new and old syllabus topicwise?
