no3.16.0405*New functionality*
* Added new functionality for specifying valid order quantities by intervals. This is enabled for custom products and makes it possible to say that a product has a minimum of 50, maximum of 5000 and intervals of 50, which previously only could be achieved by adding ALL valid order quantities manually.

*Bugfix*
* When setting minimum and maximum order-quantity to the same number the validation of order quantities was not enforced correctly allowing all quantities above the minimum.
