The overview of the changes are as follows:
Shorter Format: First to Four games sets (Tie-Break at 3-All), Best-of-Five sets, with No-Ad scoring
• Shorter set format designed to increase number of pivotal moments in a match, while the best-of-five set format does not alter the number of games required to win a match (12) from the traditional scoring format. No-Ad scoring will be played (receiver’s choice).
Shorter Warm-Up
• Matches will begin precisely 5 minutes from the second player walk-on, leading to a reduction in down time before the beginning of matches.
Shot Clock
• A shot clock will be used in between points to ensure strict regulation of the 25-second rule, as well as during set breaks, Medical Time-Outs, and the five-minute countdown from the player walk-on to the first point of the match.
No-Let Rule
• The No-Let rule will apply to serves, bringing in an additional element of unpredictability at the start of points.
Medical Time-Outs
• A limit of 1 medical time out per player per match.
Player Coaching
• Players and coaches will be able to communicate at certain points in the match (to be determined), providing additional content and entertainment value for broadcast. Coaches will not be allowed on-court.
In addition, a ‘free movement’ policy will be applied to the crowd (except behind the baselines) throughout the tournament. The policy will enable fans to move freely in and out of the stadium during matches, providing a relaxed fan-friendly atmosphere and ensuring fans are not restricted entry into the stadium at any time.

I think the shot clock and the no-let rule are obvious ones. Coaching happening without coaches being present on the court? Is this a texting situation?! I've always thought that coaching during the match is a bit irrelevant but I did enjoy the dynamic at the Laver Cup (as long as they're miked)...
