Yours is a good question,
@Hockeytchr.
Going to the parks has probably changed more than the Fort has (but both have gone through changes).
At the Fort, Trails End is no longer a buffett. It is a skillet dinner (all you care to eat). Reviews have varied.
Disney cleared out all the River Country leftovers and started preparing the land for a new joint resort/DVC building behind HoopDeeDoo and Trails End. Then stopped due to pandemic/slow sales at Riviera. The scrim is still up and not a pretty sight.
They moved the Fort beach to the right side of the dock (expanded that side) because they closed off the camper beach behind the fence for the construction noted above.
All the litter water sprite boats are gone. The old boat rental area looks terrible.
Food trucks (up to five of them) come to the area between the Settlement Trading Post and Trails End on nights when TE is closed (IIRC Tuesday and Wednesday currently). Generally positive reviews.
HDDR is still closed with no idea when it's coming back. One of our campers got a peak inside and the hall and sound system have been upgraded/refurbed.
The original Tri Circle D Ranch horse barn was torn down because it was in the construction zone for the resort/DVC and a new larger one was built across the road that goes to Wilderness Lodge.
No Exercise Trail to Wilderness Lodge. One of the internal bus lines, when it reaches the Settlement Bus Depot, changes its sign board and runs down to WL and then comes back from WL and becomes an internal bus again. It's essentially replacing the small boat to WL so you can eat/explore/spend at WL conveniently.
No small boats currently that run WL-FW-Contemp. But they've added an express bus (one) from the Settlement Bus Depot to the Magic Kingdom bus stop and back.
A playground was built between Settlement TRading Post and TE where there was a grassy area in the past.
Golf cart parking across from HDDR and TE has been expanded (sand/dirt) which took out a lot of trees ("Pioneer Woods", we used to call that space).
Golf cart rentals are now for FW guests only, no day guests.
No Chip & Dale Singalong yet. But there is a nightly movie still and campfire.
Premium Meadows category of sites carved out of Premium (loops closest to pool and Meadow TP). PM are more expensive.
Speaking of expensive, rates keep going up. And folks keep filling the Fort up.
I'm sure I've left out some things.
