= 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.
