Hi Devs, We recently updated the term "Service Group" with "Cartridge Group" to make it more sensible in Composite Application Model. The main reason for this was that those groups are aggregating cartridges, not services.
Even though we did this change we did not update the REST API method context, it was defined as /groups. Since groups is a more generic term I have now renamed it to /cartridgeGroups. The reason for this change is that once we announce 4.1.0-alpha developer preview, we might not be able to do any changes to the API definition. With this modification I have updated the REST API Reference documentation and all the sample applications. If you have any local artifact deployment scripts please update them accordingly.
