Hello, i was wondering if there is a risk that custom created classes can be incompatible with future versions if itop?

What i am referring to is if i create a new object following this guide.
http://www.combodo.com/wiki/doku.php?id=customization:add-class-sample

Will the data in that class still be "usable" with future versions of itop?
