    🔄 Changed

    • 🗄 We deprecated support for Python 3.4 in Certbot and its ACME library. Support for Python 3.4 will be removed in the next major release of Certbot. certbot-auto users on RHEL 6 based systems will be asked to enable Software Collections (SCL) repository so Python 3.6 can be installed. certbot-auto can enable the SCL repo for you on CentOS 6 while users on other RHEL 6 based systems will be asked to do this manually.
    • --server may now be combined with --dry-run. Certbot will, as before, use the staging server instead of the live server when --dry-run is used.
    • --dry-run now requests fresh authorizations every time, fixing the issue where it was prone to falsely reporting success.
    • ⚡️ Updated certbot-dns-google to depend on newer versions of google-api-python-client and oauth2client.
    • 🐧 The OS detection logic again uses distro library for Linux OSes
    • 🚚 certbot.plugins.common.TLSSNI01 has been deprecated and will be removed in a future release.
    • 🚚 CLI flags --tls-sni-01-port and --tls-sni-01-address have been removed.
    • The values tls-sni and tls-sni-01 for the --preferred-challenges flag are no longer accepted.
    • ✂ Removed the flags: --agree-dev-preview, --dialog, and --apache-init-script
    • acme.standalone.BaseRequestHandlerWithLogging and acme.standalone.simple_tls_sni_01_server have been deprecated and will be removed in a future release of the library.
    • certbot-dns-rfc2136 now use TCP to query SOA records.
