<p>An additional argument has been added to the <span class="bold"><strong>pgin</strong></span> and
<span class="bold"><strong>pgout</strong></span> functions provided to the memp_register function.
The application should be searched for any occurrences of
memp_register. For each one, if <span class="bold"><strong>pgin</strong></span> or <span class="bold"><strong>pgout</strong></span>
functions are specified, the <span class="bold"><strong>pgin</strong></span> and <span class="bold"><strong>pgout</strong></span> functions
should be modified to take an initial argument of a <span class="bold"><strong>DB_ENV *</strong></span>.
This argument is intended to support better error reporting for
applications, and may be entirely ignored by the <span class="bold"><strong>pgin</strong></span> and
<span class="bold"><strong>pgout</strong></span> functions themselves.</p>
