Meet the new X-Cart v5.3.6.
Upgrade to the new version is available to developers only so that we could test it together and make sure everything is okay before the upgrade is available in all the X-Cart stores. If your X-Cart installation is set to receive updates with the Developer wave, you are welcome to upgrade your store and share your feedback with us. We’re always here to answer all your questions about X-Cart 5.
