Cedar-14 app build disablement previews
Change effective on 01 October 2020
On April 3, 2020, we communicated the extension of the Cedar-14 EOL window to November 2, 2020 due to the COVID-19 pandemic.
Today, we are announcing temporary Cedar-14 build disablement previews on October 19 and October 26 to bring awareness to the impending EOL. During these temporary build disablements Cedar-14 apps will continue to run, but you will not be able to build and deploy new versions, emulating the Cedar-14 EOL window closure.
Cedar-14 EOL time table:
- May 3, 2018: Heroku announced deprecation of Cedar-14 for April 2019.
- May 1, 2019: EOL window for Cedar-14 began. Apps on Cedar-14 will continue to run, build, and receive security updates. Apps and builds running on later stacks will not be affected.
- April 3, 2020: Postponed the Cedar-14 Build EOL to November 2nd, 2020.
October 19, 2020: First build disablement preview for Cedar-14 apps at the following time:
- UTC: 17:00 - 21:00

October 26, 2020: Second build disablement preview for Cedar-14 apps at the following time:

- November 2, 2020: The updated EOL window for Cedar-14 will end. Apps on Cedar-14 will continue to run, but will not build or receive security updates. Apps running on later stacks will not be affected.
We advise you to upgrade your apps to a more recent stack as soon as possible.
To get a list of your apps that use Cedar-14, 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"
