++2013-02-23  Jay Berkenbilt  <ejb@ql.org>
++
++	* Bug fix: properly handle overridden compressed objects.  When
++	caching objects from an object stream, only cache objects that,
++	based on the xref table, would actually be resolved into this
++	stream.  Prior to this fix, if an object stream A contained an
++	object B that was overridden by an appended section of the file,
++	qpdf would cache the old value of B if any non-overridden member
++	of A was accessed before B.  This commit fixes that bug.
