I also had not noticed a menorah in one of the windows on Main Street.
The other new change is the Jingle Cruise overlay of decorations at the Jungle Cruise. Although not as immersive as either the Haunted Mansion Holidays or the it's a small world overlay, the minor touches are fun. I can see an increase in decorations in years to come. My favorite addition was one I was not able to get a picture, but it is the tiger with one of the jungle skipper Holiday hats. The additions are cute especially those in the waiting line.
