=== Usage ===
:{{tji|Diff4|diff|old: oldid|label|section: section name}}

*: <code>prev</code>{{snds}}Compare with the previous version of a page.
*: <code>next</code>{{snds}}Compare with the next version of a page.
*: ''id''{{snds}}This should be ''larger'' than <code>oldid</code> (when <code>oldid</code> is specified).
* {{para|old|oldid}} 
*: <code>''oldid''</code>{{snds}}The base ID onto which the diff is generated (optional). Parameter name <code>|old=</code> must be specified.
* <code>''label''</code>{{snds}}Text to display as link (optional). No label will generate a numbered link as the label.{{pb}}
* {{para|section|section name}}
*: <code>''section name''</code>{{snds}}The name of the section or anchor (optional) within the page intended to be the target of the link. Parameter name <code>|section=</code> must be specified.

===Examples===
{| class="wikitable"
! Code
! Output
|-
| {{tlx|Diff4|123456789}}
| {{Diff4|123456789}}
|-
| {{tlx|Diff4|123456789|An edit by User:Pgp688}}
| {{Diff4|123456789|An edit by User:Pgp688}}
|-
| {{tlx|Diff4|123456789|Same edit as above but links to "External links" section|section{{=}}External links}}
| {{Diff4|123456789|Same edit as above but links to "External links" section|section=External links}}
|-
| {{tlx|Diff4|123456789|old{{=}}4611964|All changes at article leading up to Pgp688's edit}}
| {{Diff4|123456789|old=4611964|All changes at article leading up to Pgp688's edit}}
|}

Unlike {{tl|Diff2}}, this template does not automatically determine the user's intended target when <code>''diff''</code> and <code>''oldid''</code> are both specified. Be sure to use correct numbers. If the IDs belong to different pages, the link will not work.{{pb}}See below:

{| class="wikitable"
! Code
! Output
|-
| {{tlx|diff4|123456789|old{{=}}123456788|Changes between revisions 123456789 and 123456788}}
| {{diff4|123456789|old=123456788|Changes between revisions 123456789 and 123456788}}
|}
