Nuget.org missing most recent versions

I've still got a few old projects that use MVC4.  I noticed that on [NuGet.org](https://www.nuget.org/packages/AttributeRouting/) them most recent version of AttributeRouting listed is 3.4.2, however, the most recent version in the repo is [v3.5.6](https://github.com/mccalltd/AttributeRouting/releases/tag/v3.5.6).

Would it be possible to get atleast the most recent version added to NuGet.org?
