-### Use a feature flag to roll out a `latest` template
-
-With a major version release like 13.0 or 14.0, [stable templates](#stable-version) must be
-updated with their corresponding [latest template versions](#latest-version).
-It may be hard to gauge the impact of this change, so use the `redirect_to_latest_template_<name>`
-feature flag to test the impact on a subset of users. Using a feature flag can help
-reduce the risk of reverts or rollbacks on production.
-
-For example, to redirect the stable `Jobs/Deploy` template to its latest template in 25% of
-projects on `gitlab.com`:
-
-```shell
-/chatops run feature set redirect_to_latest_template_jobs_deploy 25 --actors
-```
-
-After you're confident the latest template can be moved to stable:
-
-1. Update the stable template with the content of the latest version.
-1. Remove the migration template from `Gitlab::Template::GitlabCiYmlTemplate::TEMPLATES_WITH_LATEST_VERSION` const.
-1. Remove the corresponding feature flag.
-
-NOTE:
-Feature flags are enabled by default in RSpec, so all tests are performed
-against the latest templates. You should also test the stable templates
-with `stub_feature_flags(redirect_to_latest_template_<name>: false)`.

 ### Static Site Editor

 The Static Site Editor was deprecated in GitLab 14.7 and the feature is being removed in GitLab 15.0. Incoming requests to the Static Site Editor will be redirected and open the target file to edit in the Web IDE. Current users of the Static Site Editor can view the [documentation](https://docs.gitlab.com/ee/user/project/static_site_editor/) for more information, including how to remove the configuration files from existing projects. We will continue investing in improvements to the Markdown editing experience by [maturing the Content Editor](https://gitlab.com/groups/gitlab-org/-/epics/5401) and making it available as a way to edit content across GitLab.
