Recently I noticed that the creators have released an update to version 1.21. From what I can tell, this version only adds support for Windows Vista, so it may not be an important upgrade if (like me) you have no plans to buy Vista.
In my aforementioned article, I wished that the creators of DriveImage XML would add the ability to create scheduled backups. I must give them credit – the software now has this ability, though it was added in a version previous to 1.21. This alone is incentive to upgrade if you are still using a much older version.
