Difference between Wsus 3.0 and Wsus 4.0

Hi all,

I would like to know what are differences between Wsus 3.0 and Wsus 4.0.

I have already notice that for Local Publishing, the method IPublisher.PublishPackage(sourcePath,additionalSourcePath, packageDirectoryName), totally ignore the "additionalSourcePath" parameter.

Are there any documentation or web site where I can find differences between Wsus 3.0 and 4.0 ?

Thanks.
