With the continuous growth of the Dev4Press, over the past year many things were changed to improve user experience and support. More such changes are coming and they will be introduced on March 4 2012. This will include improvements to forum, products info and more.
GD Products Center is under heavy development at the moment, and it will require a major change to the code that will save the data for products. This change will affect only some of the property types that can be used for products, to allow for fast data filtering and search.
