As of August 17, 2023, Dependabot will no longer support Python 3.6 or 3.7, which have reached their end-of-life. If your code uses these versions, Dependabot will no longer be able to open pull requests in your repository and will log errors. Update to at least Python 3.8 to ensure your code is secure and Dependabot can still run.
