InnerGrid (and IG V) are the ancestors of Fura. From 2001 to 2006, GridSystems developed the InnerGrid family under a proprietary software licensing model. InnerGrid has been discontinued, but some of our customers still use IG V, so we provide support for them under special contracts. Yet, we encourage all our customers and communities to either update to Fura Enterprise Edition or start using Fura in the Cloud. Please, feel free to contact us if you require any further information.
