 <p>{% trans %}The core History module tracks when each logged-in user has most recently visited each content item page on the site. This allows content to be marked as <em>new</em> or <em>updated</em> for each user, meaning that it was newly created or has been updated since the last time they visited its page. These records are kept for one month, meaning that content older than one month is never marked as new or updated.{% endtrans %}</p>
