Ah, we should add an {% else %} clause to the {% ifchanged %} tag --
that'd be a nice addition.
For this solution, you could use {% regroup %}. The {% regroup %} tag
is pretty complex and kind of hard to understand, but it's powerful
for times like these.
{% regroup post_list by created as date_list %}
(Now post_list is a list of objects grouped by distinct "created" values.
Each one has a "grouper" and a "list" attribute.)
{% for date in date_list %}
<tr><th class="info" colspan="2"><span class="date">
{{ date.grouper|date:"Y.m.d" }}
</span></th></tr>
{% for entry in date.list %}
{{ entry.headline }} ...whatever
{% endfor %}
<hr />
{% endfor %}
