Phabricator is an open-source software development platform. In Wikimedia, many projects use Phabricator for project management, software bug reporting and feature requests (see How to report a bug).
Go to Wikimedia Phabricator
Get started
Phabricator is for software bug reports, feature requests, and planning work.
  • To ask technical questions about Wikimedia projects, see m:Tech
  • To ask technical questions about MediaWiki in non-WMF installations, see Project:Support desk
If you have questions, check the Help page. Your questions are very welcome.
For a basic overview what Phabricator is and can do, watch the tutorial videos (or see these slides if your bandwidth is limited).
Common first actions are:
Weekly update / maintenance window
Phabricator doesn't have releases, and therefore it is up to us to decide how close do we want to follow the upstream version. There is a weekly window for updates and other maintenance tasks on Wednesdays at 5:00PM Pacific (Thursday Midnight, 0:00 UTC) (check your timezone) and users will get redirected to Phabricator/Maintenance​. We don't necessarily update Phabricator every week, but we reserve this window to use as needed, usually twice per month, depending on the urgency of outstanding bugs fixed upstream. The expected downtime during this window is between 0 and 30 minutes.
For specific bugs and changes, query for resolved tasks of the latest update date under "Milestones" and check the corresponding latest upstream Changelog items.
