We do not allow gems that are fetched from Git repositories. All gems have

to be available in the RubyGems index. We want to minimize external build
dependencies and build times.
## License compliance
Refer to [licensing guidelines ](licensing.md ) for ensuring license compliance.

## Upgrade Rails
When upgrading the Rails gem and its dependencies, you also should update the following:
- The [`Gemfile` in the `qa` directory ](https://gitlab.com/gitlab-org/gitlab/-/blob/master/qa/Gemfile ).
- The [`Gemfile` in Gitaly Ruby ](https://gitlab.com/gitlab-org/gitaly/-/blob/master/ruby/Gemfile ),
to ensure that we ship only one version of these gems.
You should also update npm packages that follow the current version of Rails:
- `@rails/ujs`
- `@rails/actioncable`
