Browser Performance Testing has run in a job named `performance` by default. With the introduction of [Load Performance Testing](https://docs.gitlab.com/ee/ci/testing/code_quality.html) in GitLab 13.2, this naming could be confusing. To make it clear which job is running [Browser Performance Testing](https://docs.gitlab.com/ee/ci/testing/browser_performance_testing.html), the default job name is changed from `performance` to `browser_performance` in the template in GitLab 14.0.
By default, the Code Quality feature has not provided support for Ruby 2.6+ if you're using the Code Quality template. To better support the latest versions of Ruby, the default RuboCop version is updated to add support for Ruby 2.4 through 3.0. As a result, support for Ruby 2.1, 2.2, and 2.3 is removed. You can re-enable support for older versions by [customizing your configuration](https://docs.gitlab.com/ee/ci/testing/code_quality.html#rubocop-errors).
By default, the `Ruby.gitlab-ci.yml` file has included Ruby 2.5.
To better support the latest versions of Ruby, the template is changed to use `ruby:latest`, which is currently 3.0. To better understand the changes in Ruby 3.0, please reference the [Ruby-lang.org release announcement](https://www.ruby-lang.org/en/news/2020/12/25/ruby-3-0-0-released/).
