Change effective on 21 October 2015
Heroku recently updated parts of its infrastructure. As a result of this update, the number of CPU cores visible to free, hobby, 1X and 2X dynos has changed.
Heroku is continually updating its infrastructure, so we recommend using WEB_CONCURRENCY instead of container metrics like CPU or memory to optimize dyno resource use.
