Well if you've seen the Topics on the left-side from that link (i.e. SEO, etc), it is described there what features were added and so on. Anyway, I'll try to provide as much details I can give for you here:
- Ajax-based mini cart (Minicart.UseAjaxAddToCart)
- Configurable URL-rewrites– Allows URL to be customized for search engine optimization (SEO) purposes
i.e.
Code:
<!-- AspDotNetStorefront Default Url Patterns -->
<add name="Product" url="p-{ProductID}-{SEName}.aspx" virtualPath="~/showproduct.aspx" checkPhysicalUrlAccess="false" />
<!-- <add name="Product" url="product/{ProductID}/{SEName}.aspx" virtualPath="~/showproduct.aspx" checkPhysicalUrlAccess="false" />-->
<add name="Category" url="c-{CategoryID}-{SEName}.aspx" virtualPath="~/showcategory.aspx" checkPhysicalUrlAccess="false" />
<!--<add name="Category" url="category/{CategoryID}/{SEName}.aspx" virtualPath="~/showcategory.aspx" checkPhysicalUrlAccess="false" />-->
- Addin - allows a developer to add custom logic to the storefront through addin system. Configurations -> Advanced -> Addin Manager
- Mobile browsing - automatically switch the skin to a streamlined mobile-friendly skin
- Ajax appconfig design - editing has become simplified by design.
- Multiple payment gateways - can now be selected within the software as a security precaution. Should the primary gateway call fail, the software will immediately roll over to the backup gateway.
- New improved product & entity maintenance pages
- New friendly error message handling (System.ShowFriendlyErrors and System.ErrorHandlingEnabled)
Hope this helps.
