<p>The names of two fields in the lock statistics changed in the Berkeley DB 4.4
release. The <span class="bold"><strong>st_nconflicts</strong></span> field was renamed to be
<span class="bold"><strong>st_lock_wait</strong></span>, and the <span class="bold"><strong>st_nnowaits</strong></span> field was renamed to
be <span class="bold"><strong>st_lock_nowait</strong></span>. The meaning of the fields is unchanged
(although the documentation has been updated to make it clear what these
fields really represent).</p>
