PLEASE NOTE: The plugin now uses the built-in Wordpress Custom Post Type system. This allows for more flexibility, better SEO, better deep linking, better caching, etc but it may change the relationships your site has with the store pages and products. Be sure to make a backup and if possible, test on a dev environment first!
ADDITIONAL NOTE: This plugin is meant to be customized! It will work "out of the box" with just about any theme, but it may not match your site or be as "pretty" as you'd like. Additionally, if your theme uses featured images in the header of posts, you may have to make adjustments to ensure the display of the products is to your liking.

In order to upgrade from a previous version you will need to follow the steps below:
Once installed, the easiest way to upgrade to future versions is to use the automatic upgrade feature built into WordPress. You will be automatically notified of any updates to the plugin and given the option to install them with a single click.
