Does this apply if one is simply changing planes without leaving the airport?
Absolutely YES!!! I, too, have to update my ESTA information...

Q: Do nationals or citizens of countries that participate in the VWP require an ESTA™ if they are only transiting the United States en route to another country? A: Yes. The United States no longer has a Transit Without Visa program, so eligible nationals or citizens of countries that participate in the VWP will require either an ESTA™ or a visa to transit the United States. If a traveler is only planning to transit through the United States en route to another country, when he or she completes the ESTA™ application, the traveler should enter the words "In Transit" and his or her final destination location in the address lines under the heading “Address While In The United States”.
