<p>
Databases can now be configured as heaps by passing the access type
<code class="literal">DB_HEAP</code> to <a href="../api_reference/C/dbopen.html" class="olink">DB-&gt;open()</a>. Heap size can be
configured with <a href="../api_reference/C/dbset_heapsize.html" class="olink">DB-&gt;set_heapsize()</a>, and <a href="../api_reference/C/dbstat.html" class="olink">DB-&gt;stat()</a> now returns heap
statistics in the structure <code class="literal">DB_HEAP_STAT</code> when
applied to a heap database.
