Description
Hi 👋
This project uses Heroku's heroku/buildpacks:20 CNB builder image:
https://github.com/search?q=repo%3Asuperfly%2Fflyctl%20(heroku%2Fbuilder-classic%20OR%20heroku%2Fbuildpacks)&type=code
We have deprecated this builder image as of https://github.com/heroku/cnb-builder-images/pull/429.
Please migrate to heroku/builder:22 or heroku/builder:20, to continue to receive security updates, and to avoid disruption when the build time deprecation warning is upgraded to an error in the future.
More information on the difference between the various builder images can be seen here:
