Right now I am using zen-cart 1.3.8de and I would like to update to 1.3.9f de. How I should proceed? I am using also some additional modules like: stock by attributes, HoverBox3, image-handler, Scrolling Sideboxes. What is the best solution for me? Thank you in advance for help. Template for zencart 1.3.8 will also fit to 1.3.9f ?
