I know the series 66 changed in 2010 - any changes since?

I am a bit strapped for cash and a friend gave me study guides from 2010. I don't think I need the full review courses. I passed the CFP a year ago and in the process of getting a masters in financial planning so I just need pinpointing of the materials covered and practice questions. But I wanted to make sure I am using materials that are still relevant to the test before investing the time studying it.

TIA!
