On Jan 25th, X-cart released the latest version of the 4.4.x branch. 4.4.5 is now available for download. If you downloaded it prior to January 30th, you will want to re-download it as they found a bug and updated the version with the fix for it. You can view more details and a change log on this X-cart Forum thread.
