• Claudia and Ladish/gladish/laditools/python-laditools no longer exist. Specifically, the LADI tools are out of Debian, and Claudia depended on them. They are anyway replaced/replaceable by RaySession.
• patchage is gone because it is out of Debian and can easily be replaced by RaySession, Carla, or qjackctl patchbays.
• gtklick is gone because it has been removed from debian and does not seem to be used (see here and there) and can easily be replaced by gtick. Note that a gtklick package still exists to ease the transition to gtick (but it is empty).

• The nano-basket software disappears because it doesn't pack directly anymore and should be investigated. Since no one seems to use it, I'll use my time for something else
• The spek, and tinyeartrainer software are gone because they are out of Debian. Ditto: nobody seems to use them.
• The simplesysexxer package disappears completely. In LibraZiK-3, it was already a “transition” package, i.e. an empty package but causing the installation of another package: sysexxer-ng.
• raul disappears because it is out of debian and doesn't seem to be used.
• kmidimon is gone because it was removed from debian and doesn't seem to be used.
• mididings disappears because it was removed from debian and doesn't seem to be used.
• calf-ladspa is gone because it no longer exists in debian.
• jackeq is gone because it has been removed from debian and doesn't seem to be used.

Some software that was present in LibraZiK-3 has not (yet) been put in LibraZiK-4. The reason for this is that it takes time to do and I'm not sure if they are really used.
