Thread:Project:Support desk/auto-update a mediawiki upload?

We present the latest install file (*.zip) for our product on our mediawiki. We would like to update this file automatically from our daily build WITHOUT having to manually create a new link to it. Is anyone aware of a technique or extension that might enable this scenario? Have tried replacing the uploaded file manually with a new file that is named the same, but the link from the wiki breaks and will no longer retrieve it.

MediaWiki 1.20.2 PHP 5.3.8 (cgi-fcgi) MySQL 5.0.51b-community-nt

Thank you very much for any help, Jeff Freund
