 There are currently a few exceptions to the "use package name" rule:
 
-* **packaging**: used for changes that change the npm package layout in all of our packages, e.g. public path changes, package.json changes done to all packages, d.ts file/format changes, changes to bundles, etc.
-* **changelog**: used for updating the release notes in CHANGELOG.md
-* **sample/#**: for the example apps directory, replacing # with the example app number
-* none/empty string: useful for `style`, `test` and `refactor` changes that are done across all packages (e.g. `style: add missing semicolons`)
-<!-- * **aio**: used for docs-app (angular.io) related changes within the /aio directory of the repo -->
