Maintainers ↑

This page describes the current module, library, and extension maintainers of Ruby.

Module Maintainers ↑

A module maintainer is responsible for a certain part of Ruby.

A submaintainer of a module is like a maintainer. But The submaintainer does not have authority to change/add a feature on his/her part. They need consensus on ruby-core/ruby-dev before changing/adding. Some of submaintainers have commit right, others don’t.
