title: 4.6.1 framework update leaves web.config httpRuntime still at 4.5?
body: <p>i recently upgraded our c# Web Applications to use .net framework 4.6.1 from 4.5 and only today noticed in the web.configs the  .net version differs from the  .net version. 
  Everything seems to work fine in production but my questions is, since the httpRuntime did not auto change to 4.6.1, i'm curious if thats intentional or do i need to manually key that in or is there some other reason for it to be on 4.5?</p>
