1.3.4 Document Versions

Documents in the Windows protocols documentation set are assigned a version number that changes each time the document is updated. The title page of each document contains a revision summary table that shows the top-level history of changes to the document. This revision summary table contains the date of each release and the corresponding version number, revision class, and comment that describes the change.

The version number and revision class are correlated as shown in the following table:
