Here is a summary (I took it off of another site) of the proposed changes if you do not want to read through all the material on the link:
1. The random draw shall take place immediately before or after weigh-ins.
(Currently the random draw can happen only immediately after weigh-ins.)
2. A school may be represented by a second competitor in the 135, 140, 145, and 152 pound weight classes.
(Currently only one wrestler per weight class is allowed per school.)
3. No wrestler shall represent the school in more than one weight class in any meet or compete in more than five matches, including forfeits in any one day of any dual meet tournament. In individual tournament competition, the five match limit is waived and a 30 minute total time (excluding overtime) will be used to determine eligibility to continue to compete in the tournament. If a competitor enters a bout and time would run out (30 minute total) the competitor will be allowed to finish that bout.
(Currently the 5-match rule is in place for dual tournaments and individual tournaments. The 30 minute rule is not in place.)
4. [For duals] Coaches will be allowed to place two chairs in a restricted area at the corner of the mat.
(Currently all of a school's chairs are together during a dual, including the coaches' chairs.)
5. During tournament competition, a minimum of one adult school representative and a maximum of two team personnel (Coaches and/or non-participating contestants) will be permitted on chairs at the edge of the mat.
(Currently there is no minimum.)
6. It is permissible to allow coaches on the corner of the mat in a restricted zone. This line shall be painted or taped on the mat at the appropriate locations.
(Currently there are no painted or taped markers for the coaching zone.)
.
7. If no tights are worn, a suitable undergarment shall be worn.
(Currently the rule that a suitable undergarment is required when tights are not worn is not in the rulebook.)
8. A female wearing a male singlet must wear a tight-fitting, short sleeved undershirt under the singlet of single, solid color unadorned with no more than one manufacturer
