There is only one major change in this version. When an advertiser uploads an image for their ad, if it is not exactly the size of the ad slot, then it is automatically cropped and resized to be exactly the correct size. The advertiser is warned that this occurred and told to check the image to ensure that it is satisfactory. Because of this the "exact size" option in the advertising section was removed as unnecessary.
Small changes to the navigation appearance as well.
