This is the problematic commit:

commit f5918bdcc05d7924dc204b57307023eb1ef011f0

    LaTeX export: use org-export-latex-hyperref-format
    
    * lisp/org-latex.el (org-export-latex-links) : Replaced hard coded
    hyperref format with custom
      variable `org-export-latex-hyperref-format'

Note that href is not same as hyperref.
