However, for your own projects, we strongly advise pinning each module to the exact version\n\u003e you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic\n\u003e approach for updating versions to avoid unexpected changes.\n\n\n\n\n\n\n\n\n\u003c!-- markdownlint-disable --\u003e\n## Makefile
