At the same time as we deployed the free account, we also released the following improvements:
The "Payment" link is now named "Upgrades" and you can manage your subscription from there. The new tiers are included. Note that if you wish to upgrade your account, you first have to cancel your current subscription.
Campaign Edit Visibility is now easier and more secure. The visibility buttons now include checks to make sure you can't make mistakes. The Campaign Details now also has the button bar like in the campaign list.
Facebook sharing and several other issues have been resolved.
