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.
