Minor Version Comments Not Displaying For All Users

Hi all,

I have an issue with a document library in my business. The document library is set up so that only library owners and authors of documents can see minor versions. For the rest of the business, only major versions are visible when visiting the library.  This is necessary because we cannot have people using draft versions - only the last approved major version should be used.

The issue I have is that I want all users to be able to see the check-in comments of minor versions. Currently, only the author and site owners can see the minor version comments. The rest of the business can only see the major version comments. 

In the screenshot below, you can see the minor version comments (eg. 3.1 and 3.2) in the top screenshot, as viewed by the author. In the bottom screenshot, you can only see the major version comments (2.0, 3.0 and 4.0), as seen by a site visitor. 

This means that people utilising the document do not have clear visibility of what has changed. Is there any way to fix this so that visitors can see all version comments, while only being able to access approved major versions?
