• Upgraded base distribution to Debian 11.1/Bullseye.
  • caching proxy:
    • Switch from Polipo (only cached http and is no longer available in Debian) to Squid. Squid is configured as a caching http/https proxy. Using 'squid-openssl' package, it is configured to act as a MITM (man in the middle) caching proxy - closes #1560.
  • fab:
    • Port code to python3 and major code refactoring.
    • Use new 'turnkey-chroot' library for use in 'fab-chroot'.
    • Use xorriso (instead of genisoimage) for generating ISO. This provides UEFI boot support (note this only supports booting the ISO via UEFI; additional work in di-live required to complete UEFI install support). Part of #1435. NOTE: The UEFI support started for v17.0 di-live and ISO builds has been (temporarily) rolled back and won't be implmented in v17.0.
  • pool:
    • Port code to python3 and major code refactoring. Closes #1272.
    • (Still not pre-installed by default).
  • bootstrap:
    • Include 'ca-certificates' package (to support https apt repos via squid https proxy).
  • corestrap:
    • Support the option of using a "corestrap", rather than a minimalist bootstrap. A corestrap is a bootstrap, but with all core packages (except the kernel) pre-installed. It is larger than the bootstrap, but speeds up builds significantly.
  • Note: Please refer to turnkey-core's 17.0 changelog for changes common to all appliances. Here we only describe changes specific to this appliance.
