Iis – What differences are between IIS 7.0 and IIS 7.5

asp.netasp.net-mvciisiis-7iis-7.5

I thought that IIS 7.0 and IIS 7.5 have (from the application developer point of view) nearly same features. Then, I found that certain features are not working on IIS 7.0. Are there more features available in IIS 7.5 that are missing in IIS 7.0 (that application developer should know)?

(Maybe not core IIS features, but some other ASP.NET (MVC) features that are working on IIS 7.0.)
