The Wrestling Rulebook is published every 2 years, and 2017-18 is the start of the current 2 year cycle (2017-18 and 2018-19). Almost all rule changes occur in the summer leading up to the season in question, approved, then published by the NCAA. Rarely are changes made at the in-between years, so it's unlikely any significant changes are made next summer and into 2018-19.
Here's the rule changes that should be most visible by fans...
1.8.2 Facial hair is allowed, trimmed and skin visible for medical exam, max 1/2 inch.
3.13.5 Foam brick is required to indicate coaches challenges.
3.14.3 Overtime tiebreaker, each wrestler has choice of top, bottom, or neutral.
3.22.5 Max limit on wrestled matches at 6 per day per wrestler.
4.2.3 Establishes a neutral "danger zone" takedown. This one has been discussed often here. I can provide the exact language if you want it.
5.7.15d The Offensive wrestler is ALWAYS responsible for returning the defensive wrestler to the mat in rear-standing position. Note that all the pictures and comments stating otherwise were removed from the rulebook.
8.3.1 Wrestlers required to certify by November 1 (was the 1st day of practice, October 10th previously)
8.3.9 Eliminates the February 15 deadline for descent to a lowest allowable weight class.
