Code Stewards
Code Stewards are ultimately responsible for the development policies, support, and overall health of the code in question. As MediaWiki continues to grow and become further depended on by millions of users, it has become increasingly important that the code-base remains healthy while also enabling the continue evolution of its capabilities. Code Stewards enable this by committing to a base level of support such as bug fixes and code reviews. For more information regarding stewardship, please see Development policy/Code Stewardship.

Frontend and backend libraries that are published by Wikimedia and bundled with MediaWiki core.

Upstream projects and libraries
There are many upstream projects on which MediaWiki, extensions, and/or Wikimedia depend. Some of them were "invented here", as stand-along libraries, or split out as part of the Library infrastructure for MediaWiki project. Some of them are widely-used third party tools to which community members provide improvements or support. Others are merely used with gratitude.
