Your Heroku account has one or more apps running on the Heroku-16 stack, which reaches end-of-life on May 1st, 2021.
What do I need to do?
Please upgrade your Heroku-16 apps to a newer stack using our Dev Center Guide.
What will happen to apps that are not upgraded?
From March 15th, 2021: To ensure all users notice the end-of-life warnings, a Heroku-16 app’s first deploy of the week will fail; all subsequent deploys are unaffected and your apps will continue to run. The frequency of these periodic alerts will increase as the end-of-life date draws closer, as outlined in the linked changelog article.
From May 1st, 2021: Heroku-16 will have reached end-of-life. Existing Heroku-16 apps will continue to operate, but they will no longer receive security updates and they will run at your own risk.
From June 1st, 2021: The building of Heroku-16 apps will no longer be allowed. All other non-build functionality will continue to work, and the apps will continue to run.
