Think of it as a digital laboratory where community members can preview
upcoming software and give feedback to help improve them. This special
preference page lets designers and engineers experiment with new features on
a broad scale, but not in a disruptive manner.
Beta Features is released on all wikis worldwide on November 7, 2013. You
can test it now on MediaWiki.org <http://MediaWiki.org/> and on TestWiki.
Beta Features was developed by the Wikimedia Foundation's Design, Multimedia
and VisualEditor teams. Along with other developers, they will be adding new
features to this experimental program every few weeks.
Enjoy, and don't forget to let us know what you think!
