Manual talk:$wgRestrictDisplayTitle

what would be a use case for this setting set to true? NSK Nikolaos S. Karastathis 23:18, 23 October 2008 (UTC)
 * iPod, among other things. -- Skiz zerz  00:39, 24 October 2008 (UTC)
 * No, for iPod, $wgAllowDisplayTitle = true would be sufficient.
 * For concrete use cases you'd have to ask the dozens of people who asked about this on the #mediawiki channel. I suppose people like to be able to control the display title completely -- especially, to shorten it. So the page Manual:Foo/Bar could show the title "Bar". Another use case would be the ability use characters in the title that are illegal in page names: the page called Pre-Tag could show the title &lt;pre&gt;. -- Duesentrieb ⇌ 07:42, 24 October 2008 (UTC)


 * This setting (set to false) is especially useful for multilingual wikis: your wiki can display "Main Page" for the English version and "Página Principal" for the Portuguese version at "Main Page/pt", for instance. Capmo 17:37, 30 March 2009 (UTC)


 * It is also very useful when using url parameters to change the contents of a page: http://xn--ssongsmat-v2a.nu/ssm/N%C3%A4ringsv%C3%A4rde_f%C3%B6r?livsmedel=%C3%84pple+m+skal rotsee (talk) 12:01, 18 January 2013 (UTC)

MediaWiki 1.22 change not covered in Release notes
I cannot find anything in the Release_notes/1.22 that covers the statement "Additionally, some inline CSS rules like display: none; which can cause the text to be hidden or unselectable are disallowed. MediaWiki version:	= 1.22" --Peculiar Investor (talk) 18:24, 8 December 2013 (UTC)
