Features

System Wide

Added support for full language files other than English. Chinese has been added to this version.
Added the ability to filter the transaction report in the admin to show only transactions that have not been processed by the datafeed. Additionally, you can process individual unfed transactions by clicking on the link in the details of the transaction.
When a transaction is completed by the datafeed fails an email is now sent to all users with access to that store.
Added ^^sub_token_url^^ as a valid place holder for the receipt email template.
Added the ability to cancel your own FoxyCart subscription directly from the admin.
The FoxyCart admin is now completely versioned as of 060. This will give us increased flexibility to update the admin and add new features without breaking existing live stores.
Added language customization support for PayPoint Gateway, PayPal Payflow Pro, and Cybersource.
You can now get rated shipments from FedEx provided you have your Account Number, Production Password, Production Meter Number and Authentication Key.
Improved FedEx error messages
You can now directly add and remove user access to your FoxyCart store admin. Just use the new add user menu item.

Checkout

True guest checkout support with configurable options in the admin under the checkout template. The customer experience on the checkout can be either guest and account (defaulting to account), guest and account (defaulting to guest), guest only or account only.
Paypal Express is now supported as a payment gateway option.
Multiple Payment options are now supported on the checkout including Purchase Order, Credit or Debit card and Paypal express.
In the admin, you can now specify how you would like the customer's address to be rated. It can either bet to commercial, residential or you can have it dynamically determine one or ther other based on if they field in the company field.
Added the Issue Number and Start Date for Maestro and Solo UK debit cards.
Added a "receipt continue" url to the admin so this value no longer has to be set via JavaScript. This is where the customer will land after hitting continue on the receipt. The default behavior is to return to the initial referrer URL or the store's home page if there isn't a referrer.
Added URL encoding to Google analytics and if no product code was provided as the SKU for Google, the product name is used.

API

Implemented subscription_get and subscription_cancel API calls using the sub_token or the sub_token_url.

Improvements, Notes, & Bug Fixes

Cart

Improved the method in which an "update" is required on the cart after changing quantities. Removed the span.fc_cart_notice elements as part of this change.

Added the classes fc_text and fc_text_short to the quantity input fields on the cart.

Fixed a bug where cart=updateinfo breaks if you currently have something in your cart. Now it empties your cart first (patched back to 0.5.1).
Added custom classes for product options, based on the option name. So, for example, a custom product option named color would yield a class of fc_cart_item_color on the parent <li> element.
All html is now stripped from the data sent to the cart.

When emptying the line items from the cart, coupons are now also removed.
