OpenSSL 3.0.0 released
Version 3.0 of the OpenSSL TLS library has been released; the large version-number jump (from 1.1.1) reflects a new versioning scheme.

Certbot
A command line is a way of interacting with a computer by typing text-based commands to it and receiving text-based replies. Certbot is run from a command-line interface, usually on a Unix-like server. In order to use Certbot for most purposes, you’ll need to be able to install and run it on the command line of your web server, which is usually accessed over SSH.
