<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>We have a feed with 2 items one 1 month old and one 6 months old.<br>
"Discard items older than" is set to "3 months and 3 weeks".<br>
This keeps only one item in the db.<br>
I change "Discard items older than" to Never and update the feed items.</p>
<p>Expected outcome: I have 2 items<br>
Outcome: I have only 1 item</p>
<p>This is due to the fact that the feed hasn't changed and "if ($has_new_content)" condition is not met, hence the items are not imported again.</p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>The hash should be based on the "Discard items older than" value too.</p>
