 ### Removed
 
+- Removed the deprecated `heroku/nodejs-npm` from the buildpack group for npm support ([#625](https://github.com/heroku/buildpacks-nodejs/pull/625))
 - Removed `heroku/procfile`, since it's being added directly to the Heroku builder images instead. If you override the Heroku builder images' default buildpack detection order (or use this buildpack with a non-Heroku builder image), you will need to append `heroku/procfile` to your buildpacks list.
