Introducing Test CloudApps - In order to help CAT developers during the design and testing phase of CATs as well as simplify the End User experience, we have introduced the notion of Test CloudApps. Test CloudApps are any CloudApp launched from the Designer UI and they are hidden from End Users. For more details, see Testing CATs on our docs site.
Pricing Support - Building upon the recent addition of Spot or On-Demand pricing support for ServerArray and Server resources in API 1.5, you can now also specify Spot or On-Demand pricing when launching raw instances via API 1.5.
