Predictably with such a long time between updates there have been major changes. Along with a number of minor bug fixes, and an updated UI, the application has been fully updated to support iOS4 and the iPhone 4's retina display.
Reporting for MS Azure and the Rackspace Cloud has been added in addition to the existing status reporting for Google App Engine, Google Apps and Amazon Web Services.
The best part? This new release of Cloud Status is now available for free thanks to the generous support of WatchMouse, the application and website monitoring people.
