versionchanged / versionadded annotation titles missing in downloadable docs

[Ulrich Petri]

The downloadable docs don't contain the titles for the versionchanged / versionadded annotations. The html source contains the respective divs with optional content but the "New in Django ..." and "Changed in Django ..." title spans are missing.

Example from the html version (ref/settings.html#engine):

Online version:

<div class="versionchanged">
    <span class="title">Changed in Django 1.9:</span> 
    <p>The <code class="docutils literal"><span class="pre">django.db.backends.postgresql</span></code> backend is named <code class="docutils literal"><span class="pre">django.db.backends.postgresql_psycopg2</span></code> in older releases. For backwards compatibility, the old name still works in newer versions.</p>
</div>

Downloadable version:

<div class="versionchanged">
    <p>The <code class="docutils literal"><span class="pre">django.db.backends.postgresql</span></code> backend is named <code class="docutils literal"><span class="pre">django.db.backends.postgresql_psycopg2</span></code> in older releases. For backwards compatibility, the old name still works in newer versions.</p>
</div>

To clarify, the "downloadable docs" are at ​https://docs.djangoproject.com/m/docs/django-docs-dev-en.zip.

The script to build them is at ​https://github.com/django/djangoproject.com/blob/master/docs/management/commands/update_docs.py. I'm not sure if the problem is in that script or somewhere else.
