Changes

MatterControl requires Mono version 3.10 or above. MatterControl works best with Mono 4.4. As of this writing (12/29/16) Earlier versions are not supported. There is a bug in an issue with Mono 4.6 and later that prevents the cloud services from establishing a full connection. The [[Cloud/Connection_Display | connection indicator]] will remain yellow. All other features are fully functional.

If you are on an older version of Ubuntu (before Xenial 16.04 LTS) or Fedora Debian that does not have the latest Mono then you can add the official Xamarin repository to get up to date. The official MatterControl download currently comes with a shell script to do this automatically on Debian based distros.
