A new parameter has been added to the comparison

<div class="itemizedlist">
|

<ul type="disc">

<a href="../api_reference/C/dbset_bt_compare.html" class="olink">DB->set_bt_compare()</a>

parameter required in the callback's signature. It is

intended for internal use only. In customer code, the
|
||
parameter must be set to <code class="literal">NULL</code>.
