PrestaShop 1.7 has been officially released after extensive beta testing, featuring a complete overhaul with the introduction of the Symfony2 framework primarily affecting the back office's product and module pages. It also includes a new 'classic' default theme and a 'starter theme' designed for easier custom theme creation, along with a reworked product management interface aimed at simplifying use for non-coders. The module listing has been redesigned to resemble an app store, enhancing user experience with better organization and accessibility for both installed and recommended modules.
