Some input for improving user output of whonixcheck Whonix News Update Notification is needed here.
Current messages are, when Whonix Debian Packages are outdated:
Whonix News Download Result: Installed Whonix Debian Package $whonix_deb_package_version is outdated! You can automatically update using Whonix's internal updater. Please update using: sudo apt-get update && sudo apt-get dist-upgrade
Or when Whonix’s Build Version is outdated (This is what happened when Whonix moved from Debian testing [Whonix 7] to Debian stable [Whonix 8] and updating using apt-get Whonix Debian Packages wasn’t supported, the whole build version was declared deprecated. The goal is not to do this again, but still, you’ll never know and it’s good having this option around.)
Whonix News Download Result: Whonix Build $whonix_build_version is outdated! Sorry, automatically updating this Whonix version is not possible. You have to manually download a new Whonix image.
Both messages doesn’t say “no devs are putting thought into these versions which are declared outdated anymore, for security reasons you should update”, because “outdated” doesn’t mean “not safe”.
