Extra Product Fields has been updated to allow a new permanent Product Type field to select which extra fields are available for entry during product editing. Types can have nested sub-types and extra fields can be restricted to any or all product types and will automatically be available for any sub-type for the types to which they are available.

New configuration variables control how (or if) the Product Type is displayed in the catalog and whether it can be directly searched (it will appear in the new Advanced Quick Search box if it can) or used to filter the product listing.

The extra field listing filter code has been rewritten to be intelligent so that, just as with the existing osCommerce Category/Manufacturer filter, the filters will only display if more than one value for the filtering field exists in the product listing being browsed and only the values that are used in that listing will be shown in the drop down menu.
