We've discovered two critical bugs in 2015 SP1 that require a hotfix. Note that these bugs only affect SP1, so if you're running 2015 without SP1 these bugs do not affect you. Here is an overview of the bugs:

• Google Analytics ecommerce tracking does not record sales
  
• The Foundation4 Responsive theme, and themes derived from the SP1 version of it, prevent non-US customers from checking out in Firefox and Chrome due to browser validation of the postal code field

Also included in the hotfix is an update to the enhanced link attribution code for Google Analytics (what's that?) and support for the latest Bing Ads (formerly Microsoft AdCenter) conversion tracking code.

How Do I Get It?
If you have a current BV.NEXT plan you can download the hotfix from your account right now. If your BV.NEXT plan has expired you can renew it from the downloads page.

Installation
Installation is simple. Download "BV Commerce 2015 - hotfix #1" from your account and unzip the file. Copy the contents of the \www folder to the root of your website. Note that if you've made any customizations to your site you will want to merge your changes with these files. Also, if your site theme was created from the "Foundation4 Responsive" theme you will want to merge the changes to this theme with your theme.
