Getting the build number of the hero from environment variables on the cedar stack

I noticed that Heroku has a build version number, i.e. v251 when you deploy to a hero. Is there a way that I can read that from my application, maybe an environment variable? I have a node.js application on a cedar stack.

Not directly, but if you can access the Heroku API, you can get it from Heroku releases.

UPDATE

Run heroku releases and analyze the results in an environment variable each time you deploy.

How about using Dyno Metadata . It looks like the data you need is just an environment variable.
