Deployments

Upcoming major(ish) software deployments and operations changes. For past deployments, see Software deployments/2011 archive. For an exhaustive list of past site changes, see Server admin log. For our long-term roadmap, see mw:Roadmap. Please provide UTC times for all deployments (PDT times optional).

This page is hosted on wikitech because it needs to be accessible during site outages.

• Scheduling: If you see a potential conflict with your upcoming deployment, please mail out to private-l@lists.wikimedia.org to discuss.
• Communicating: Every major or new feature deployment should be announced on the Wikimedia blog; you can ask Guillaume (gpaumier@wikimedia.org) for support. For routine and maintenance deployments, listing them here is enough.

• Reminder - daylight savings time has begun for most timezones in the US (PST -> PDT)! When recording both UTC and PDT times, remember that PDT is GMT -7
