SharePoint Major Version and Minor Version

A major version is usually one that represents a milestone, such as completion of an outline or a chapter. Major versions are numbered with whole numbers, such as 3.0, 4.0, and so on.

A minor version represents interim check-ins while a particular file is under development. Minor versions are numbered with decimals, such as 4.1, 4.2, 4.3, and so on.

In many organizations, versioning is set up so that only the owner of the file and people who can approve items can see minor versions. In others, it is set up so that anyone who can edit files in the library, or anyone who has Read permission to the library, can see all versions.

Note: Major and minor versions are available in libraries, but not in lists.

Limiting the number of versions is generally a good practice. It means you can conserve space on the server and reduce clutter for users. But, if your organization is required to save all versions for legal or other reasons, do not apply any limits.

• When you check out a file in a versioning-enabled library, a new version is created every time you check it back in. And, if major and minor versions are part of the configuration of your library, you can designate, at check-in, which type of version you are checking in. In libraries where check-out is required, versions are only created upon check-in.

• In libraries where check-out is not required, a new version is created the first time you save after opening the file. Each subsequent save overwrites the version that you created with the first save. If you close the application and then reopen the document, the first save will, once again, produce a version. This can cause the number of versions to proliferate very rapidly.
