What Are Versions?

Document libraries and lists in SharePoint have an option to track versions.

This option stores old versions of files or items each time a change is made. For example, if a user What Does Check-in/Check-out Mean? 27 uploads a document, and then another user edits the document and saves it, SharePoint saves the original document as a version of the file. Later, users can look at the version history of the file and choose to open a specific version or restore it (that is, make that version the current one).

SharePoint supports two types of versioning. In the first type, each change is regarded as a major change, and the version numbers go from 1 (the first time a document was uploaded) to 2 (after the first change) and then 3 and 4 and so on.

In the second type, each change is regarded as a minor change, unless the user specifies that it is a major one. The version numbers go from 0.1 (the first time a document was uploaded) to 0.2 (the first change) and so on, until a user selects the option to perform a major change, and the version number changes to 1.0, and subsequent changes raise it to 1.1, 1.2, and so on.
