Cedar-14 stack end-of-life window begins 1 May 2019

Change effective on 01 May 2019

Cedar-14 EOL has been extended until November 2, 2020 due to the COVID-19 pandemic.

In accordance with Heroku’s stack update policy, the Cedar-14 stack was previously deprecated on 3 May 2018, and the end-of-life (EOL) window has begun as of 1 May 2019. Apps running on the Cedar-14 stack will continue to run, but you should upgrade your apps to a more recent stack as soon as possible.

For one year, apps running on the Cedar-14 stack will continue to build, and Heroku will continue to apply critical security updates to the stack.

To get a list of your apps that use the Cedar-14 stack, run the following two commands:

$ heroku plugins:install apps-table
$ heroku apps:table --filter="STACK=cedar-14"

You can also show apps by team:

$ heroku apps:table --team=my-team --filter="STACK=cedar-14"

See the Cedar-14 End-of-Life FAQ for more information.
