VAssure enables Authors to manage several versions of one document.

Version management allows:

reviewing older versions of content
comparing different versions side by side
reverting to older versions of content
removing selected older versions

It is possible to have the following versions of a document:

published: one only
approved/unapproved: one only
pending: one only
last closed: one only
closed: multiple versions

An Author can choose which version of a document will be used as the initial content for a new version. It may be that the last editable version contains less correct information than the version before that. Alternatively it may be a new version of the document is needed that looks more like an older version.
