Build-key command from easy-rsa package disappeared?

Hello all
After an upgrade from 18.04 to 20.04 we noticed that some commands we used to create certs, are not present anymore.
Does anyone know if this command was superseded?
The command is build-key (/usr/share/easy-rsa/build-key)

The package name is easy-rsa. It appears Focal got a new major version (2.2.2-2 -> 3.0.6-1) and as a result, some of the binaries are different.

Consider checking out the upstream docs, which also have some notes about version 3.0.
