Starting from this version CelesteCS Math add-on is provided in two versions: for Confluence Server and Confluence Cloud. Both add-ons share the same code base, thus most new features will appear in both versions. CelesteCS Math Cloud add-on is hosted on Google App Engine servers, so it becomes a highly-available and secure solution, but at the same time it is still simple and easy to use. CelesteCS Math add-on is still hosted on parent Confluence Server's host.
