Greetings,

The Wikimedia Foundation will be upgrading MediaWiki to version 1.18 on all Wikimedia sites over the next weeks.

The upgrade will happen in at least three stages; we will display a CentralNotice banner for each stage, focusing on the wikis affected.

The English version of the landing page is at http://meta.wikimedia.org/wiki/Wikimedia_maintenance_notice

Please help update the localized landing page in your language if it exists. You may also create a new subpage for your language if it doesn't already exist.

You can also check that there is a translation of the banner itself in your language at http://meta.wikimedia.org/wiki/CentralNotice/Generic_maintenance_notice

Thank you in advance. I'm available if anyone has questions or comments.
