Minor versions for SharePoint custom list

Question

I developed a custom SharePoint 2007 list with one custom content type derived from Item. The problem is that I only get major versions that enable version control in the list. Is it possible to get a small version in a user list? If not, does anyone know a good approach to how this might be done for a custom list.

Answer 1

Minor versions are available only for lists based on SPDocumentLibrary, that is, for SPListItems there must be an associated SPFile. I think you're out of luck if you don't decide to implement the minor version as a custom column and save it using a custom ItemEventReceiver. Ugh.
