For more information on the new Web API service, please visit the Web API page.

The new Web API interface improves the performance and functionality of the web service (User Story #3586). For more information on the new Web API service, please visit the this page.

It is now possible to have multiple instances of inmation services running on the same machine. This means that multiple Connectors can be installed on a single computer or a Connector and Server can be installed on the same machine but can be independent of one another and considered part of different systems. For more information about installing separate service instances, please visit the system documentation section. (User Story #3884)
