All right, I have finished the second version of the patch.

What do you think?

* lisp/ox-html.el (
org-html-mathjax-options,

): Update to MathJax 3 while maintaining compatibility with MathJax 2.
All legacy options get converted automatically, except for the 'path'
option which must now point to MathJax 3 or later and not MathJax 2.

+*** HTML export uses MathJax 3+ instead of MathJax 2
+
+Org 9.6 uses MathJax 3, a ground-up rewrite of MathJax 2 released
+in 2019.  The new version brings modularity, better and faster
+rendering, improved LaTeX support, and more.
+
+For more information about new features, see:

+https://docs.mathjax.org/en/latest/upgrading/whats-new-3.1.html
+https://docs.mathjax.org/en/latest/upgrading/whats-new-3.2.html
+
+For instance, one can typeset calculus with the built-in =physics=
+package or chemistry with the built-in =mhchem= package, like in
+LaTeX.
+
+During the export, Org automatically converts all legacy MathJax 2
+options to the corresponding MathJax 3+ options, except for the =path=
+which must now point to a file containing MathJax version 3 or later.
+
+Further, if you need to use a non-default =font= or =linebreaks= (now
+=overflow=), then the =path= must point to MathJax 4 or later.
+
+See the updated =org-html-mathjax-options= for more details.

+To maintain compatibility with pre-9.6 Org that used MathJax 2,
+the following conversions take place.
+
+The legacy \"autonumber\" option, with the value \"AMS\",
+\"None\", or \"All\", becomes the \"tags\" option set to the
+value \"ams\", \"none\", or \"all\", respectively.
+
+Any legacy values of the \"scale\" option, specified as
+percentage strings, become converted to unit-interval numbers.
+For example, a legacy scale of \"150\" becomes a scale of 1.5.
+
+The legacy \"linebreaks\" option, with the value \"true\" or
+\"false\", becomes the \"overflow\" option set to the value
+\"linebreak\" or \"overflow\", respectively.
+
+The legacy values of the \"font\" option, namely \"TeX\",
+\"STIX-Web\", \"Asana-Math\", \"Neo-Euler\", \"Gyre-Pagella\",
+\"Gyre-Termes\", \"Latin-Modern\", become converted to the
+corresponding MathJax 4+ font names.
+
+Legacy options and values always take precedence.
