# 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]](https://blade.ruby-lang.org/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.
