3.11.0

• Potentially breaking change: wpsc_add_to_cart() now checks the $_REQUEST super global, rather than $_POST. This allows for future features, such as populating carts from a URL token, etc. Anywhere you may have code that checks for $_POST, in this context, it should now check $_REQUEST. See #1852.
• Fix: Improvements to internationalization across the board, including updates to introduce compatibility for translate.wordpress.org.
• Fix: Show admin notice if administrator has not set any target markets. See #711.
• Fix: Check post_status more stringently in single page template controller. See #844.
• Fix: The Google Analytics integration was calculating products once, not once per quantity in the cart. See #1718.
• Fix: The Google Analytics integration was incompatible with the Yoast Analytics plugin. See #1736.
• Fix: Resolve scenarios where variation combinations for products that were unavailable could still allow for cart addition (adding the parent product, rather than the variation). See #1373.
• Fix: Order totals on sales log page did not count Closed Orders, but did Orders Received. This has been reversed, as that is the paradigm used throughout the rest of the project. See #1728.
• Fix: Deleting a purchase log now also deletes the purchase meta associated with that log. See #1877.
• Fix: Deleting a purchase log now also deletes the download status entries for that log. See #1964.
• Fix: In the rare occurrence that an insert for a purchase log entry fails, we now return an error saying so. See #1892.

• Enhancement: General performance improvements surrounding meta retreival, especially for countries. Including caching, cache invalidation, etc. See #1894.
