# 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.

- The maintainer fixes bugs of the part. Particularly, they should fix security vulnerabilities as soon as possible.

- They handle issues related the module on the Redmine or ML.

- They may be discharged by the 3 months rule [ruby-core:25764].

- They have commit right to Ruby’s repository to modify their part in the repository.

- They have “developer” role on the Redmine to modify issues.

- They have authority to decide the feature of their part. But they should always respect discussions on ruby-core/ruby-dev.

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.
