Since 2013... I know I can't help a ton, but here are some changes. I'm sure others will chime in!
Main Street Electrical Parade is the current night-time parade.
There will be no railroad or Rivers of America attractions running, due to Star Wars Land construction. However, you can tour a docked Mark Twain on the river.
The trail from Big Thunder Mountain to Fantasy Land is closed the majority of the time.
No Big Thunder Ranch, petting zoo, or BBQ.
There's an overlay on Space Mountain, making it Hyperspace Mountain.
No more Captain EO.
Starbucks on Main Street.
New security checkpoints at Downtown Disney, Grand Californian Hotel, Mickey and Friends parking lot.
Ursela's grotto is closed.
Anna and Elsa meet in Animation Academy where the zoetrope was.
No Muppets show.
No night time dance party in DCA.
Frozen instead of Aladdin in the Hyperion Theatre.
Tower of Terror had their final check out a few weeks ago. (Attraction is closed for rethemeing.)
