v3.0.0

• Add support for DNS-01 challenges.
  • Check out the list of all currently supported authenticators.
  • This also means it is now possible to request wildcard certificates!
  • PR by XaF.
• Make it possible to define which authenticator to use on a certificate basis.
  • Like with ECDSA/RSA, you can add the authenicator's name in the cert_name to override the default.
  • PR by XaF.
• Make it possible to use same cert_name across multiple config files.
  • The scripts will remember all domain names associated with the cert name.
  • This means you can now use as many config files as you want and have them all point to a single certificate.
• Add BATS.
  • A lot unit tests for the Bash functions we use in the util.sh file.
  • Also add it as a GitHub action.
  • A huge thank you to XaF for providing the foundation for this.
• Add ability to override found server_name.
  • By adding a comment on the server_name line the script will now use that instead.
  • This enables you to easily group domains under a common wildcard certificate (example config).
• Any server name beginning with '~' will be ignored.
  • This character means that the server name is a regex, and we cannot use it when requesting certificates.
• Use ECDSA certificates by default.
  • You now have to explicitly set USE_ECDSA=0 to disable this.
• We aren't actually introducing any breaking changes, but such a large change deserves a major release.
• Update documentation.
• Update examples.
