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

Item syntax:
 * Project name
 * [Qualifier keyword] Action item [Owner(s)] [Completion keyword]

Examples:
 * New unicorn engagement
 * [Needs consensus] Deploy unicorns [Brion/Tim]
 * Deploy unicorns [Brion/Tim] [DONE]

Continuous Responsibilities

 * Code review
 * RT review / ops tasks
 * Community extension review and deployment
 * Bug triages and general bug fixes
 * New extension deployment (Review queue)
 * Labs maintenance
