The March 3, 2011 revision adds a configuration variable that determines whether you are allowed to create unending sale prices. This will appear under My Store in Configuration. If set to true then the expiration date for the sale can be left blank to create sale prices that never expire. If set to false a valid expiration date will be required in order to create a new sale price or named sale. Note that this only applies when you create or edit a sale, it does NOT have any effect on sale prices that are already stored in the database. All of the PHP files for this contribution have been updated to accommodate this new feature.

The complete contribution is enclosed with update instructions for those who already have installed it. Upgrade basically involves replacing all of the admin side PHP files for the contribution, installing a new configuration variable into the database, and making some minor modifications to one function in admin/includes/functions/general.php to allow for reposting variables.
