Maintainers

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

Branch Maintainers

A branch maintainer is responsible for backporting commits into stable branches and publishing Ruby patch releases.

The list of current branch maintainers is available in the wiki.

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.

No maintainer means that there is no specific maintainer for the part now. The member of ruby core team can fix issues at anytime. But major changes need consensus on ruby-core/ruby-dev.

Bundled gems upstream repositories and maintainers

The maintanance policy of bundled gems is different from Module Maintainers above. Please check the policies for each repository.

The ruby core team tries to maintain the repositories with no maintainers. It may needs to make consensus on ruby-core/ruby-dev before making major changes.
