I'm filling in for our SP admin, who is unreachable, and can't figure out which permission level I need to assign so that a group of users only see major versions of documents.
Apparently someone who should only be able to see major versions has been able to see a minor version of a document on our SharePoint site (They saw v1.11). It could be that the offending content was part of 1.0 thus permissions aren't the real issue but I'm investigating this as a first step.
AFAIK I would be applying the permissions to entire folders and not to particular documents.
