Certbot 4.0 now supports six day TLS certificates

Certbot 4.0 has introduced support for Let’s Encrypt's new capability of issuing six-day TLS certificates, offering enhanced security by preventing long-term compromises due to private key exposure. The Certbot update includes dynamic renewal features, triggering at 1/3rd or 1/2 of the certificate's lifetime, promoting automation and reducing reliance on the revocation process. Users can choose between traditional 90-day cycles or shorter lifespan options using ACME profiles, allowing for a more agile and secure web experience.
