+- **Participants**: A list of users participating or watching a merge request.
+- [**Notifications**](../../profile/notifications.md): A toggle to select whether
+  or not to receive notifications for updates to a merge request.
+
+## Close a merge request
+
+If you decide to permanently stop work on a merge request,
+GitLab recommends you close the merge request rather than
+[delete it](#delete-a-merge-request). Users with
+Developer, Maintainer, or Owner [roles](../../permissions.md) in a project
+can close merge requests in the project:
+
+1. Go to the merge request you want to close.
+1. Scroll to the comment box at the bottom of the page.
+1. Following the comment box, select **Close merge request**.
+
+GitLab closes the merge request, but preserves records of the merge request,
+its comments, and any associated pipelines.
+
+### Delete a merge request
+
+GitLab recommends you close, rather than delete, merge requests.
+
+WARNING:
+You cannot undo the deletion of a merge request.
+
+To delete a merge request:
+
+1. Sign in to GitLab as a user with the project Owner [role](../../permissions.md).
+   Only users with this role can delete merge requests in a project.
+1. Go to the merge request you want to delete, and select **Edit**.

+
+WARNING:
+This feature might not be available to you. Check the **version history** note above for details.
+
+You can create a status check that sends merge request data to third-party tools.
+When users create, change, or close merge requests, GitLab sends a notification. The users or automated workflows
+can then update the status of merge requests from outside of GitLab.
+
+With this integration, you can integrate with third-party workflow tools, like
+ServiceNow, or the custom tool of your choice. The third-party tool
+respond with an associated status. This status is then displayed as a non-blocking
+widget within the merge request to surface this status to the merge request author or reviewers
+at the merge request level itself.
+
+The lack of a status check response does not block the merging of a merge request.
+
+You can configure merge request status checks for each individual project. These are not shared between projects.
+
+To learn more about use cases, feature discovery, and development timelines,
+see the [external status checks epic](https://gitlab.com/groups/gitlab-org/-/epics/3869).
+
+## View the status checks on a project
+
+Within each project's settings, you can see a list of status checks added to the project:
+
+1. In your project, go to **Settings > General**.
+1. Expand the **Merge requests** section.
+1. Scroll down to the **Status checks** sub-section.
+
+![Status checks list](img/status_checks_list_view_v14_0.png)
+
+This list shows the service name, API URL, and targeted branch.
+It also provides actions to allow you to create, edit, or remove status checks.
+
+## Add or update a status check
+
+### Add a status check
+
+Within the **Status checks** sub-section, select the **Add status check** button.
+The **Add status check** form is then shown.
+
+![Status checks create form](img/status_checks_create_form_v14_0.png)
+
+Filling in the form and selecting the **Add status check** button creates a new status check.
+
+### Update a status check
+
+Within the **Status checks** sub-section, select the **Edit** button
+next to the status check you want to edit.
+The **Update status check** form is then shown.
+
+![Status checks update form](img/status_checks_update_form_v14_0.png)
+
+Changing the values in the form and selecting the **Update status check** button updates the status check.
+
+### Form values
+
+For common form errors see the [troubleshooting](#troubleshooting) section below.
+
+#### Service name
+
+This name can be any alphanumerical value and **must** be set. The name **must** be unique for
+the project.
+The name **has** to be unique for the project.
+
+#### API to check
+
+This field requires a URL and **must** use either the HTTP or HTTPs protocols.
+We **recommend** using HTTPs to protect your merge request data in transit.
+The URL **must** be set and **must** be unique for the project.
+
+#### Target branch
+
+If you want to restrict the status check to a single branch,
+you can use this field to set this limit.
+
+![Status checks branch selector](img/status_checks_branches_selector_v14_0.png)
+
+The branches list is populated from the projects [protected branches](../protected_branches.md).
+
+You can scroll through the list of branches or use the search box
+when there are a lot of branches and the branch you are looking
+for doesn't appear immediately. The search box requires
+**three** alphanumeric characters to be entered for the search to begin.
+
+If you want the status check to be applied to **all** merge requests,
+you can select the **Any branch** option.
+
+## Delete a status check
+
+Within the **Status checks** sub-section, select the **Remove...** button
+next to the status check you want to delete.
+The **Remove status check?** modal is then shown.
+
+![Status checks delete modal](img/status_checks_delete_modal_v14_0.png)
+
+To complete the deletion of the status check you must select the
+**Remove status check** button. This **permanently** deletes
+the status check and it **will not** be recoverable.
+
+## Troubleshooting
+
+### Duplicate value errors
+
+```plaintext
+Name is already taken
+---
+External API is already in use by another status check
+```
+
+On a per project basis, status checks can only use a name or API URL once.
+These errors mean that either the status checks name or API URL have already
+been used in this projects status checks.
+

+- Extracting a portion of the `source` paths from the `sources` element and combining them with the
+  class `filename` path.
+- Checking if the candidate path exists in the project.
+- Using the first candidate that matches as the class full path.
 
-As an example scenario, given the project's full path is `test-org/test-project`, and has the following file tree relative
-to the project root:
+#### Path correction example
 
-```shell
-Auth/User.cs
-Lib/Utils/User.cs
-src/main/java
-```
+As an example, a project with:
 
-In the Cobertura XML, the `filename` attribute in the `class` element assumes the value is a
-relative path to project's root.
+- A full path of `test-org/test-project`.
+- The following files relative to the project root:
 
-```xml
-<class name="packet.name" filename="src/main/java" line-rate="0.0" branch-rate="0.0" complexity="5">
-```
+  ```shell
+  Auth/User.cs
+  Lib/Utils/User.cs
+  src/main/java
+  ```
 
-And the `sources` from Cobertura XML with paths in the format of `<CI_BUILDS_DIR>/<PROJECT_FULL_PATH>/...`:
+In the:
 
-```xml
-<sources>
-  <source>/builds/test-org/test-project/Auth</source>
-  <source>/builds/test-org/test-project/Lib/Utils</source>
-</sources>
-```
+- Cobertura XML, the `filename` attribute in the `class` element assumes the value is a relative
+  path to the project's root:
 
-The parser extracts `Auth` and `Lib/Utils` from the sources and use these as basis to determine the class path relative to
-the project root, combining these extracted sources and the class filename.
+  ```xml
+  <class name="packet.name" filename="src/main/java" line-rate="0.0" branch-rate="0.0" complexity="5">

-If for example there is a `class` element with the `filename` value of `User.cs`, the parser takes the first candidate path
-that matches, which is `Auth/User.cs`.
+- `sources` from Cobertura XML, the following paths in the format
+  `<CI_BUILDS_DIR>/<PROJECT_FULL_PATH>/...`:
 
-For each `class` element, the parser attempts to look for a match for each extracted `source` path up to `100` iterations. If it reaches this limit without finding a matching path in the file tree, the class will not be included in the final coverage report.
+  ```xml
+  <sources>
+    <source>/builds/test-org/test-project/Auth</source>
+    <source>/builds/test-org/test-project/Lib/Utils</source>
+  </sources>
+  ```
+
+The parser:
+
+- Extracts `Auth` and `Lib/Utils` from the `sources` and uses these to determine the `class` path
+  relative to the project root.
+- Combines these extracted `sources` and the class filename. For example, if there is a `class`
+  element with the `filename` value of `User.cs`, the parser takes the first candidate path that
+  matches, which is `Auth/User.cs`.
+- For each `class` element, attempts to look for a match for each extracted `source` path up to
+  100 iterations. If it reaches this limit without finding a matching path in the file tree, the
+  class is not included in the final coverage report.
 
 NOTE:
-The automatic class path correction only works on `source` paths in the format of `<CI_BUILDS_DIR>/<PROJECT_FULL_PATH>/...`. If `source` will be ignored if the path does not follow this pattern. The parser assumes that
-the `filename` of a `class` element contains the full path relative to the project root.

+# Merge request widgets **(FREE)**
+
+The **Overview** page of a merge request displays status updates from services
+that perform actions on your merge request. All subscription levels display a
+widgets area, but the content of the area depends on your subscription level
+and the services you configure for your project.
+
+## Pipeline information
+
+If you've set up [GitLab CI/CD](../../../ci/README.md) in your project,
+a [merge request](index.md) displays pipeline information in the widgets area
+of the **Overview** tab:
+
+- Both pre-merge and post-merge pipelines, and the environment information, if any.
+- Which deployments are in progress.
+
+If an application is successfully deployed to an
+[environment](../../../ci/environments/index.md), the deployed environment and the link to the
+[review app](https://about.gitlab.com/stages-devops-lifecycle/review-apps/) are both shown.
+
+NOTE:
+When the pipeline fails in a merge request but it can still be merged,
+the **Merge** button is colored red.
+
+## Post-merge pipeline status
+
+When a merge request is merged, you can see the post-merge pipeline status of
+the branch the merge request was merged into. For example, when a merge request
+is merged into the [default branch](../repository/branches/default.md) and then triggers a deployment to the staging
+environment.
+
+Ongoing deployments are shown, and the state (deploying or deployed)
+for environments. If it's the first time the branch is deployed, the link
+returns a `404` error until done. During the deployment, the stop button is
+disabled. If the pipeline fails to deploy, the deployment information is hidden.
+
+![Merge request pipeline](img/merge_request_pipeline.png)
+
+For more information, [read about pipelines](../../../ci/pipelines/index.md).
+
+## Merge when pipeline succeeds (MWPS)
+
+Set a merge request that looks ready to merge to
+[merge automatically when CI pipeline succeeds](merge_when_pipeline_succeeds.md).
+
+## Live preview with Review Apps
+
+If you configured [Review Apps](https://about.gitlab.com/stages-devops-lifecycle/review-apps/) for your project,
+you can preview the changes submitted to a feature branch through a merge request
+on a per-branch basis. You don't need to checkout the branch, install, and preview locally.
+All your changes are available to preview by anyone with the Review Apps link.
+
+With GitLab [Route Maps](../../../ci/review_apps/index.md#route-maps) set, the
+merge request widget takes you directly to the pages changed, making it easier and
+faster to preview proposed modifications.
