With 14.04 nearing it's LTS, getting 16.04 stable is indispensable. We intend to add this in a couple of months.
I have marked this request as accepted and $5 USD have been added to your account for the same. Once this OS is publicly available on Cloudrino, we shall add another $30 USD credit to your account.
Thank you for requesting this. We're grateful to have you on board. 😄
