Editing Help:Diff (section)

=== External links ===
The URL for a diff is based on the <code>oldid</code> value of the old revision. If a revision has oldid value 12345678, its URL is:
*<code><nowiki>https://en.wikipedia.org/w/index.php?title=PAGETITLE&oldid=12345678</nowiki></code>

You can strip the <code>title=PAGETITLE&</code> part from the URL and make it look like this:
*<code><nowiki>https://en.wikipedia.org/w/index.php?oldid=12345678</nowiki></code>

Then URLs for its diffs may take the forms:

*Diff with the current version:<br/><code><nowiki>https://en.wikipedia.org/w/index.php?diff=cur&oldid=123456789</nowiki></code>
*Diff with the previous version:<br/><code><nowiki>https://en.wikipedia.org/w/index.php?diff=prev&oldid=123456789</nowiki></code>
*Diff with version 10000001:<br/><code><nowiki>https://en.wikipedia.org/w/index.php?diff=100000001&oldid=123456789</nowiki></code>
*To show only a diff and not the page content, add <code>&diffonly=1</code> to any of the above:<br/><code><nowiki>https://en.wikipedia.org/w/index.php?diff=cur&oldid=123456789&diffonly=1</nowiki></code>

A shorter alternative to link to the diff with the previous version is:
*<code><nowiki>https://en.wikipedia.org/wiki/?diff=12345678</nowiki></code>
