This is the web page where you can see all of the changes. Lots of the London properties are going up. 212 going up and 117 going down making changes to 329 in total. (Click the image above to open in new window and then enlarge).
A number of properties are going to category 7 which is 70,000 points per night. Some have left from Category 5 to 7! Even Dublin Airport is going from 4 to 5 which is pretty hard to justify for a property you can get for about EUR100.
Coupled with the removal of the 2-for-1 offer for US credit card holders it pretty much removes any value in the programme. Time to cash in.
