Node.js support now defaults to the latest version

Change effective on 11 March 2013

Heroku Node.js now uses the latest versions of Node.js and npm by default. To use a specific version of Node.js and/or npm in your app, edit the engines section of your package.json:

{
  "name": "myapp",
  "version": "0.0.1",
  "engines": {
    "node": "0.8.x",
    "npm":  "1.2.x"
  }
}

The available versions of Node.js and npm can be found here:
