+### Testing done
+
+<!-- Comment:
+Provide a clear description of how this change was tested.
+At minimum this should include proof that a computer has executed the changed lines.
+Ideally this should include an automated test or an explanation as to why this change has no tests.
+Note that automated test coverage is less than complete, so a successful PR build does not necessarily imply that a computer has executed the changed lines.
+If automated test coverage does not exist for the lines you are changing, you must describe the scenario(s) in which you manually tested the change.
+For frontend changes, include screenshots of the relevant page(s) before and after the change.
+For refactoring and code cleanup changes, exercise the code before and after the change and verify the behavior remains the same.

 ### Proposed changelog entries
 
-* Entry 1: Issue, Human-readable Text
-* ...
+- human-readable text
 
-<!-- Comment: 
-The changelogs will be integrated by the core maintainers after the merge.
+<!-- Comment:
 The changelog entry should be in the imperative mood; e.g., write "do this"/"return that" rather than "does this"/"returns that".
 For examples, see: https://www.jenkins.io/changelog/
+
+Do not include the Jira issue in the changelog entry.
+Include the Jira issue in the description of the pull request so that the changelog generator can find it and include it in the generated changelog.
+
+You may add multiple changelog entries if applicable by adding a new entry to the list, e.g.
+- First changelog entry
+- Second changelog entry
+-->
+
+### Proposed changelog category
+
+/label <update-this-with-category>
+
+<!--
+The changelog entry needs to have a category which is selected based on the label.
+If there's no changelog then the label should be `skip-changelog`.
+
+The available categories are:
+* bug - Minor bug. Will be listed after features
+* developer - Changes which impact plugin developers
+* dependencies - Pull requests that update a dependency
+* internal - Internal only change, not user facing
+* into-lts - Changes that are backported to the LTS baseline
+* localization - Updates localization files
+* major-bug - Major bug. Will be highlighted on the top of the changelog
+* major-rfe - Major enhancement. Will be highlighted on the top
+* rfe - Minor enhancement
+* regression-fix - Fixes a regression in one of the previous Jenkins releases
+* removed - Removes a feature or a public API
+* skip-changelog - Should not be shown in the changelog
+
+Non-changelog categories:
+* web-ui - Changes in the web UI
+
+Non-changelog categories require a changelog category but should be used if applicable,
+comma separate to provide multiple categories in the label command.

 ### Proposed upgrade guidelines
 
 N/A
 
-### Submitter checklist
+<!-- Comment:
+Leave the proposed upgrade guidelines in the pull request with the "N/A" value if no upgrade guidelines are needed.
+The changelog generator relies on the presence of the upgrade guidelines section as part of its data extraction process.
+-->
 
-- [ ] (If applicable) Jira issue is well described
-- [ ] Changelog entries and upgrade guidelines are appropriate for the audience affected by the change (users or developer, depending on the change) and are in the imperative mood. [Examples](https://github.com/jenkins-infra/jenkins.io/blob/master/content/_data/changelogs/weekly.yml)
-  * Fill-in the `Proposed changelog entries` section only if there are breaking changes or other changes which may require extra steps from users during the upgrade
-- [ ] Appropriate autotests or explanation to why this change has no tests
-- [ ] New public classes, fields, and methods are annotated with `@Restricted` or have `@since TODO` Javadoc, as appropriate. 
-- [ ] For dependency updates: links to external changelogs and, if possible, full diffs

+- [ ] New or substantially changed JavaScript is not defined inline and does not call `eval` to ease future introduction of Content Security Policy (CSP) directives (see [documentation](https://www.jenkins.io/doc/developer/security/csp/)).
