Extension:EmailDiff

The EmailDiff extension modifies outgoing notification emails by providing a text diff of all changes made. This enables you to see the changes without having to leave your mail client.

Edit the template
The extension works by replacing the word $PAGEDIFF in the email notification template with the actual diff. Therefore, you will need to edit the MediaWiki:Enotif_body page on your wiki to add that string.

It is recommended that you put some short summary information at the top before the diff. Here is one suggested layout:

Page: $PAGETITLE Summary: $PAGESUMMARY $PAGEMINOREDIT User: $PAGEEDITOR Time: $PAGEEDITDATE $PAGEDIFF $NEWPAGE
