Roadmap

Background: In recent years, Wikimedia Foundation's engineering planning has primarily taken place in a combination of internal goals documents and public project-level documentation. The purpose of this page is to establish a practice of sharing holistic engineering goals, initially primarily with a short term horizon, as a public document with open participation.

See also:
 * Product Whitepaper for Wikimedia Foundation product priority justifications; Strategic Plan for long-term WMF goals, some of which are engineering goals
 * Roadmap/Archive for an earlier effort to create a roadmap more focused on point releases of the MediaWiki software
 * Software deployments schedule

Previous months:
 * /2011/September
 * /2011/October
 * /2011/November
