In addition to the ability to quickly make ready-to-print PDF catalogs from the Magento database, store owners can rest easy knowing that any catalog posted to their web site is always up to date. For example, say a Magento store owner creates a PDF catalog featuring the products from the Kitchenware category.
The store owner can make sure that catalog is kept up-to-date by designating it as Always Fresh™. This is a new Catalog-on-Demand feature that automatically updates the PDF within 24 hours of any data changes. The cool thing is that the link never changes! The owner simply posts the link to the website, and never has to worry about it becoming obsolete. Read more about Catalog Edition.
