I am getting a weird thing happening with MonoDevelop. I've installed the latest versions of MonoTouch and Xamarin.Mac. MonoDevelop keeps wanting to install v3.0.5. Already e-mailed support with another pic included.
Note: MonoDevelop v3.1.0 was installed with Xamarin.Mac that I purchased. I found an update to v3.1.1 on Xamarin today - installed that. Still doing the same thing in the Stable channel. If I check for updates in the Beta channel it is showing me this for updates. I'm assuming the blue checkmark is telling me that I have the most current version installed.
