Here is a link i found that points out the significant spatial changes ,in addition to the turning radius, between ANSI 117.1 -2009 and ANSI 117.1 - 2017.
I also found a link that points out all of the sections of ANSI 117.1 - 2017 that have be altered in some way from ANSI 117.1 -2009. I don’t believe this is something you need to memorize but could be a good tool in the future.
I hope this helps. Let me know if you have any more questions.
