New configuration

Changed configuration

New user-facing features in 1.39

 * is now a wikitext built-in magic word, expanding to .  This is conventionally used as an escape mechanism to allow the use of   in unnamed template arguments.  Defining Template:= to expand to something other than   has been deprecated since 1.36, with affected pages put into a special tracking category for migration.
 * (T284020) Bot passwords are now supported when using the REST API.

Bug fixes in 1.39

Languages updated in 1.39
MediaWiki supports over 350 languages. Many localisations are updated regularly. Below only new and removed languages are listed, as well as changes to languages because of Phabricator reports.


 * Actual localization was added for several languages, which were already in Names.php and even used for a Wikipedia:
 * (T313200) Added language support for Rundi (Kirundi, rn).
 * (T310976) Added language support for Tumbuka (ChiTumbuka, tum).
 * (T314270) Added language support for Kanuri (kr).
 * (T313199) Added language support for Sylheti (syl).
 * (T311975) Added language support for Ghanaian Pidgin (gpe).
 * (T307080) Added language support for Okinawan (ryu).
 * (T307887) Added language support for Mooré (mos).
 * (T308813) Added language support for Nigerian Pidgin (pcm).
 * (T309763) Added language support for Tai Nüa (tdd).
 * (T310040) Added language support for Fante (fat).

 * (T315677) Removed French fallback from the Fula language (ff).
 * (T304920) In Swahili, The "Media" namespace is now "Media", as in English, and the "File" namespace is now "Faili". The old name of the "File" namespace was "Picha", and it's kept for backwards compatibility. If you manage a wiki in Swahili, and you use "Faili:" as a namespace anywhere in wikitext, and you mean to use it as "Media:", these need to be replaced to "Media:".
 * (T309866) Some namespace translations were updated for Kyrgyz (ky). The old ones are retained as aliases for backwards compatibility.
 * (T117845) Started the renaming of the language codes for Serbian from sr-ec and sr-el to sr-cyrl and sr-latn.
