Can modules created in one version of IVF be expected to be usable in other versions? It appears to us that modules created in IVF 10 were usable by IVF 9.1, but that is not true for modules compiled with IVF 12 when using IVF 10.
Modules and objects can be used with later compiler versions - we do not support use with older versions. We don't often change the module version but when we do it's to fix a bug or add functionality (for example, classes).
