The main changes that we implemented were aimed at making nopCommerce more store owners and store managers oriented. We wanted to ease the work with the platform for different types of users: from beginner merchants to experienced managers. Making it happen, we focused on UI and UX and simplified and redesigned admin area.

Highlight features and changes

• Absolutely new redesigned admin area (responsive). “Basic” and “Advanced” modes for settings and product details pages (a store owner can choose which product properties he wants to see/edit). This way it'll much easier for new store owners to get started with nopCommerce.
• Usage of several discounts simultaneously (cumulative discounts).
• "Color square" specification attribute type (allow filtering by this type on catalog pages).
• Conditional checkout attributes.
• Added new product attribute type Image squares. It's very similar to "color squares" attribute type. But allows a store owner can upload pictures instead of choosing of colors. Attribute value images make it more clear to the customer what they are choosing.
• Better "instore pickup" support. Allow a store owner to configure (and a customer to choose) pickup locations.
• "Ship to the same address" checkbox to the "Billing address" step during checkout (configurable disabled by default).
