Changes

# <ol><li> String Functions (via Scribunto and Lua) e.g. <nowiki>{{#invoke:String|len|This is a string whose length we want to measure}}</nowiki> gives {{#invoke:String|len|This is a string whose length we want to measure}} (requires the [[Module:String]] be added in addition to the extensions)# <li> Links to your Windows shared resources via '''Universal Naming Convention''' ([[mw:UNC links|UNC links]]) are supported. (requires changes to LocalSettings <ref><code>$wgPFEnableStringFunctions = true;</code> and <code>array_push($wgUrlProtocols, "file://");</code></ref> as well as the [[Template:Unc|unc template]] There's quite a bit of history behind this (string functions) <ref>In 2013, it was determined that this extension would never be enabled on Wikimedia wikis (see phabricator:T8455). As a workaround, use String-handling templates or [[Module:String]] https://www.mediawiki.org/wiki/Extension:StringFunctions</ref> )
