This is a major version jump from Python 3.10 to 3.14, which skips three minor versions (3.11, 3.12, 3.13). Each of these versions introduced breaking changes and deprecations. While the Dockerfile uses certbot and certbot-dns-cloudflare which are generally compatible, this large version jump increases the risk of compatibility issues. Additionally, the GitHub workflow (.github/workflows/publish-docs.yml) and pre-commit configuration (.pre-commit-config.yaml) still reference Python 3.10, which will create inconsistency between development and production environments. Consider updating those files to match, or testing with Python 3.13 first as a more conservative intermediate step.
