Helpful first

Sorry you have to deal with this. You can stay on Heroku. Here is what to change before November 1, 2026:

1. List your Heroku-22 apps. Install the apps-table CLI plugin, then run heroku apps:table --filter="STACK=heroku-22".
2. Move each app to Heroku-24 or Heroku-26. Set the new stack and fix buildpack or native library issues in a test app first.
3. Deploy before the failures start. Finish before November 1, 2026 so your deploys do not fail at a bad time.
