As many of you know, Amazon made some chnages recently and introduced some more requirements for the calls made to their datafeed. To comply with their requirements we had to change the amazon plugin core.
To update your plugin just download the latest Storestacker install.zip from halfagain.com/delivery/ (the new Amazon plugin is build in the zip, as is a free plugin) and upload the /plugins/Amazon/ folder. Then login to your store admin.php, go to Plugins menu, and click Setup for Amazon (and/or Amazon UK, whatever you use).
There are not many changes from user point of view, just one more field to fill: Amazon WebServices Secret Access Key. This is listed in your AWS account, on same page with the other key you need to fill (same as before), WebServices Access key ID
For a full store update see
http://halfagain.com/forum/help-zone/updating-your-site-to-current-versionImportant note: The new Amazon signature requests coding the request string in sha256 algo, only introduced and supported from php5. Which means that if your server still has php4, the new amazon plugin will not work. You will need to update your php version to php5 (or ask your host to do that if you are on a shared host that still use php4)
