The most eye-opening change concerns the FedEx Cup playoff-concluding Tour Championship, with top players carrying strokes-gained bonuses into the event.
The end to the FedEx Cup is great way to finish the PGA season, I can see Justin Rose finishing in real style and stamping down his authority as world number one.
In addition to the $10 million Wyndham Rewards Top 10, the existing FedExCup bonus pool will increase by $25 million, to $60 million.
"We're thrilled with these changes put forth today".
"I'm excited to have the opportunity to do something that no-one has ever done, which is pretty cool", the 2016 US PGA champion added.
The changes include a more compact schedule next season that ends August 25, a week before football begins.

The FedExCup play-offs will also be reduced from four events to three, with the Dell Technologies Championship removed from the schedule.
For a three-year stretch, the FedEx Cup Playoffs were a stage where stars shined.
East Lake Golf Club, a 7,385-yard par 70, provides players with a stiff challenge with long par 4s, water hazards and tricky greens. The next five will begin at 4-under, regressing by one stroke per five players until those ranked Nos. Under the 2019 rules, Woods would start the tournament at 2-under par, eight shots behind DeChambeau. Others need to win and get mathematical help.
Now that the 2018 Tour Championship field is locked, SportsLine simulated the event 10,000 times, and the results were surprising.
Monahan, who said the Tour considered many format changes, said he loves the beauty of the simplicity of the scoring at the playoff final. "And we have no doubt it will create a compelling, dramatic conclusion for the Tour's ultimate prize". "It's going to be interesting", said reigning FedExCup champion Justin Thomas, now No. 5 in the standings.
In next year's scenario, No. 20 Woods would start at 2 under and be 8 shots back of DeChambeau starting the 72-hole tournament.
A year ago, Xander Schauffele won the Tour Championship and Justin Thomas, the runner-up, won the FedEx Cup. "Getting that time off and getting some rest and just trying to get this thing healed up and feel good as soon as possible coming into Thursday was important". "They shared our vision for how we can challenge ourselves to raise level of excitement and fan engagement throughout the season up until the moment our FedExCup Champion is determined".
"Just a little tightness and it probably looks a little worse than it is".
