Pull Requests

Contributions to RubyGems are made via GitHub pull requests, which must be approved by a project committer other than the author. To approve a PR, a maintainer can leave a comment including the text “@bundlerbot r+”, indicating that they have reviewed the PR and approve it. Bundlerbot will then automatically create a merge commit, test the merge, and land the PR if the merge commit passes the tests.

This process guarantees that our release branches always have passing tests, and reduces siloing of information to a single contributor. For a full list of possible commands, see the Bundlerbot documentation.

Long-Term Support

RubyGems will support Ruby versions for as long as the Ruby team supports that Ruby version. That means that the latest RubyGems release will always support the currently-supported Ruby versions, and RubyGems security fixes will be released for any RubyGems version that shipped inside a currently-supported Ruby version.

Bugfix Releases

RubyGems generally releases bugfixes from the master branch. We may mix bug fixes and new features in the same release. RubyGems does not guarantee it will ship bugfix releases for previous minor or major versions.

For example, after RubyGems 2.5 is released, the RubyGems team will not provide non-security fixes for RubyGems 2.4, or any earlier versions.

Security Releases

Security releases will be made for RubyGems minor versions that were included in a currently-supported Ruby release.

For example, since RubyGems 2.0 was shipped in Ruby 2.0, RubyGems 2.0 will receive security fixes until Ruby 2.0 reaches end-of-life.

Ruby Version Support

When a Ruby version reaches end-of-life the following minor release of RubyGems will drop backwards compatibility with that Ruby version.

For example, since Ruby 2.2 has reached end-of-life, future RubyGems minor releases will only support Ruby 2.3 and above. As of this writing RubyGems is at version 2.7, so when RubyGems 2.8 is released, it will only support Ruby 2.3 and later.

Release Process

Releases of new versions should follow these steps, to ensure the process is smooth and no needed steps are missed.

Steps for security releases

  • Obtain CVE numbers as needed from HackerOne or Red Hat.
  • Agree on a release date with ruby-core, so patches can be backported to older Ruby versions as needed.
  • Avoid releasing security updates on Fridays, so platform services don’t have to work on weekends.
  • Continue with the regular release process below.

Steps for all releases

  • Confirm milestone on GitHub is complete
  • Update History.txt
  • Update Manifest.txt
  • Create and push git tag
  • Create and push rubygems-update gem and tgz
  • Publish blog post

Committer Access

RubyGems committers may lose their commit privileges if they are inactive for longer than 12 months. Committer permission may be restored upon request by having a pull request merged.

This is designed to improve the maintainability of RubyGems by requiring committers to maintain familiarity with RubyGems activity and to improve the security of RubyGems by preventing idle committers from having their commit permissions compromised or exposed.

Changing These Policies

These policies were set in order to reduce the burden of maintenance and to keep committers current with existing development and policies. RubyGems work is primarily volunteer-driven which limits the ability to provide long-term support. By joining Ruby Together you can help extend support for older RubyGems versions.
