Mono 3.0 stable has been out for a while. There just wasn't many binaries for it so you have to compile it yourself mostly.

Their download page indicates that 2.10 is the last stable version.

This is one of the reasons why I have a bad feeling about Mono (see my other comment).

In another HN discussion, a person from Xamarin said they didn't have the resources to keep Linux package management up-to-date.

However, they scored $16 million in funding this month, so going forward they certainly do have the resources.
