XV is Year 2000 Compliant!
The product "XV 3.10a" does not employ any date scheme, and as such, will be unaffected by the Y2K issue.
The same can be said for all previous versions of XV, as well.
Of course, given that XV is an image viewer/manipulator, the preceding statement would seem fairly obvious. You know it - I know it. Still, the question gets asked often enough, so there's the Official Answer. Enjoy!
