Template:Diff4/doc

Usage
Unlike diff2 this template doesn't guess users' intent. Be careful. Don't guess numbers: if IDs you specify belong to different pages, your link won't work:

Parameters

 * old:The revision to show difference since.
 * new (or first unnamed parameter, mandatory):The revision to show difference up to.
 * title (or second unnamed parameter):The caption of the link.
 * section:The section to be linked to (in new revision).
