Just to be sure, in both files, matlab.el and and matlab-mode.el?

Ok, a last question then, as Philip wrote 

,----

But what is meant by «bump the Version header"
since this header somehow seems to be determined by 
     (package-version-join
      (package-desc-version (cadr (assq 'matlab-mode package-alist))))

But if I run eval-sexep this returns 
"20191223.2012"


So I don't see any place where I manually change the Version header. Or
are we talking about adding a (git) tag?

I guess I need something  like this (stolen from auctex, who BTW use 😉
