Greetings,
The Wikimedia Foundation is planning to upgrade MediaWiki, the
software powering Wikipedia and its sister sites, to its latest
version.
The upgrade will happen in several stages over the month, starting this week.
You can still help to test it before it is enabled, to avoid
disruption and breakage.
More information:
