Changes:

• Upgraded base distribution to Debian 12.x/Bookworm.
• Configuration console (confconsole):
  • Support for DNS-01 Let's Encrypt challenges. [ Oleh Dmytrychenko github: @NitrogenUA ]
  • Support for getting Let's Encrypt cert via IPv6 - closes #1785.
  • Refactor network interface code to ensure that it works as expected and supports more possible network config (e.g. hotplug interfaces & wifi).
  • Show error message rather than stacktrace when window resized to incompatable resolution - closes #1609. [ Stefan Davis ]
  • Bugfix exception when quitting configuration of mail relay. [ Oleh Dmytrychenko github: @NitrogenUA ]
  • Improve code quality: implement typing, fstrings and make (mostly) PEP8 compliant. [Stefan Davis & Jeremy Davis
• Firstboot Initialization (inithooks):
  • Refactor start up (now hooks into getty process, rather than having it's own service). [ Stefan Davis ]
  • Refactor firstboot.d/01ipconfig (and 09hostname) to ensure that hostname is included in dhcp info when set via inithooks.
  • Package turnkey-make-ssl-cert script (from common overlay - now packaged as turnkey-ssl). Refactor relevant scripts to leverage turnkey-ssl.
  • Refactor run script - use bashisms and general tidying.

• Web management console (webmin):
  • Upgraded webmin to v2.0.21.
  • Removed stunnel reverse proxy (Webmin hosted directly now).
  • Ensure that Webmin uses HTTPS with default cert (/etc/ssl/private/cert.pem).
  • Disabled Webmin Let's Encrypt (for now).
• Web shell (shellinabox):
  • Completely removed in v18.0 (Webmin now has a proper interactive shell).
