I received mail regarding one of our apps (App ID: 311):
Subject: “[eunice-crowdbotics-311] Your app’s stack is deprecated (Heroku-16)”
From May 1st 2021, Heroku-16 will be end-of-life, and apps using it will no longer receive security updates, and be run at your own risk.
From June 1st 2021, builds will no longer be allowed for Heroku-16 apps.
Please upgrade to a newer stack as soon as possible.
See the Heroku-16 End-Of-Life FAQ for more details.
What should be our next steps, if any?
