Update the Heroku stack


AAPS users: mind the compatibility matrix!


It is good practice to maintain your Heroku stack up to date. Either when you receive an email from Heroku or when you update your Nightscout site (which is also a good habit).

  • Scroll down to the bottom of the page, select the master branch and click Deploy Branch

Hint

If you can’t select the master branch or Deploy Branch doesn’t do anything reconnect GitHub.

  • Build will start and information will scroll in the log window. Do not leave the page, do not interfere and wait for completion. It might take more than 10 minutes. Interrupting the process will lead to a broken site and you’ll need to restart deployment.

  • Wait until the deploy process completes and click View (if nothing happens click Manage App then upper right Open App)
