Hold off on upgrading to YAK version 1.3.9. There’s an annoying bug in the settings screen — for which I’ve just released 1.4.0.

The following changes are included in these 2 releases (note: replace { } with [ ] in the tags below):

• an override setting for confirmation email subject
• 2 new tags: {yak_back_to_cc} and {yak_back_to_address}, to be used on an authorize.net or paypal error page (when payment processing returns an error)
• initial support for Google Analytics (including new tag {yak_google_analytics} for the final confirmation page).
• support for html confirmation emails
• removed __autoload which was colliding with another plugin
• add proper monetary formatting to total on cart
• facility to override the message displayed when the customer’s basket is empty
• facility to embed customer details in the final confirmation page (after confirming order).
  The following tags are now available:

  {yak_customer_name}
  {yak_customer_phone}
  {yak_customer_address}
