Making endnotes clickable links with hyperref

Question

I would like to use the endnotes package, hyperref and biblatex together to have links to my endnotes. Here is a MWE that shows how the links don't show up:

\begin{filecontents}{testbib.bib}
@Book{jones00,
  author =   {Douglas Jones},
  title =    {A book},
  publisher =    {The metasyntactic variable publishing company},
  year =     2000}
\end{filecontents}

\documentclass{article}
\usepackage{endnotes}
\usepackage[autocite=footnote,notetype=endonly,style=verbose-trad1]{biblatex}
\bibliography{testbib}
\let\footnote\endnote
\usepackage{hyperref}
\begin{document}
Something\autocite[p.12]{jones00} something else\footnote{another endnote?}

\theendnotes
\end{document}

I'm open to other end-note producing options that work better with hyperref, but I'd rather stick with article document class.

Answer 1

I once uncovered the following code on comp.text.tex, credited to Ulrich Dirr:

Load it with the endnotes package (after hyperref) and enjoy.

Answer 2

It seems that this is not a biblatex issue. The hyperref README states on page 18 that the endnotes package is "[u]nsupported".

Answer 3

Use the enotez package (\usepackage{enotez}).

For details see: https://tex.stackexchange.com/a/228296/42648

Answer 4

enotez works well, but we had a problem when it was used together with a large collection of style files. Instead, defined a simple mod of endnotes that worked in that environment. Also used two options where you can click either on the note number or on the text marked with that number. The latter seems useful for small font displayed on a tablet when it is difficult to hit the very small note number. Here is a complete example.

A fuller blast ne'er shook our battlements.

What ribs of oak, when mountains melt on them,
Can hold the mortise? What shall we hear of
