Xamarin have finally released Mono-3.6.0 on 13th August 2013, which means that Kitsilano Software can ship the matching RPMs for MonoTizen. The relevant links to installation instructions have been added to the MonoTizen website.
Unfortunately this looks like this will be the last update for MonoTizen (hopefully they return) as Kitsilano Software will be concentrating on the Sailfish OS now. You can read more about this in Bob Summerwill's post entitled: Tizen is broken. We will be spending some time apart.
