Since: - It has been end of life upstream since 2023-06-27, so is no longer receiving security updates. - The buildpack has been warning about its end of life in the build log output since 2023-02-08 (see #1404, #1460). - The `setuptools` and `pipenv` packaging toos have already dropped support for Python 3.7, which means we're blocked on upgrading to newer versions of them in the buildpack. - The upgrade from Python 3.7 to Python 3.8+ in most cases requires no changes to an application at all, or else some small dependency updates (compared to say the upgrade from Python 2 to 3). - Python 3.7 is not compatible with OpenSSL 3, and so only works on the Heroku-20 stack which itself will be deprecated in 2024. - Any apps that must stay on Python 3.7 short term, can pin to the previous buildpack version (`v238`) as a stop-gap. Closes heroku/roadmap#198. GUS-W-12345803.
