The MWE below works fine with TeXLive 2019 and produces:
But with TexLive 2020 version (MacTeX) I get
! LaTeX Error: File `tikz-berge.sty` not found
! LaTeX Error: File `tikz-kiviat` not found
It seems as if these packages are no longer part of the TeXLive distribution and are marked on CTAN as having "been taken temporarily out of circulation to give the author time to investigate some problems.".
As my original question as to what happened to these pacakges was addressed in the comments (now documented in the text of this question), I am wondering what is the best way to proceed if someone needs the versions of these pacakges that were available before (and worked fine, at least for some cases that I know of).
My solution as of now is that I have the following directoes in my local tree:
texmf-local/tex/latex/tkz-berge
texmf-local/tex/latex/tkz-graph
texmf-local/tex/latex/tkz-kiviat
which contain the versions of the .sty from the TeXLive2019 release. This seems to be working as of now, but leads me to the following questions:
How do I automate the detection of a new version of this, should it be available in a future release.
The logic for removing a package that has been there for many years escapes me, especially since it was provding some working functioality. If anyone can elaboarate on this that would be useful to know.
