Announcing when languages pass the translation threshold to be exported to MediaWiki
Nike told me the translations in JSON files should be loaded anyway and I was able to select those languages in Special:Preferences, except tzm which was missing from Names.php and has since been fixed.
OK. I will add new languages to the news page as and when they appear in the log. Perhaps I will find out what a .json file is at Wikimania in London!
I have checked the list of messagesXx.php files in MW core against the list of language names and note that the language Aeb (Tunisian Spoken Arabic) also appears to be missing from the list of language names. Could you fix this also?
That's not the same thing, it might be a dummy language file; but I'll check.
As for JSON, Amir wrote a page on mediawiki.org which will hopefully be useful even before Wikimania :-), mw:Localisation file format.
