We have posted updates to the core cart downloads that address some minor issues including UPS and USPS rate generator updates, admin reporting fixes, cart stability updates and some minor PCI compliance patches to address recent changes in PCI requirements.
We will be releasing a new FULL cart release shortly but we are still working with our developers on fully testing the new features prior to posting the public download.
This is a recommend upgrade for all live installs but it is not a critical (required) update.
If you have already downloaded / installed the cart, please login to your account to download the latest version. The new files / fixes are located in the /Upgrade/ folder in the downloaded zip file.
Simply upload the folders (/sitestorepro/ and /estore_admin/) inside the /Upgrade/ folder up to your hosting account to overwrite the files/folders of the same name on your live install(s).
The upgrade will not affect any design work, customizations or data on your live installs.
