<h2>Bugs Fixed<a class="headerlink" href="#bugs-fixed" title="Permalink to this headline">¶</a></h2>
<ol class="arabic simple">
<li>When using Apache 2.4 and daemon mode, the connection and request log
IDs from the Apache child worker processes were not being copied across
to the daemon process so that log messages generated against the request
would use the same ID in logs when using the <tt class="docutils literal"><span class="pre">%L</span></tt> format modifier.</li>
<li>When using Apache 2.4 and daemon mode, the remote client port
information was not being cached such that log messages generated
against the request would use the port in logs when using the <tt class="docutils literal"><span class="pre">%a</span></tt>
format modifier.</li>

<h2>Features Changed<a class="headerlink" href="#features-changed" title="Permalink to this headline">¶</a></h2>
<ol class="arabic simple">
<li>If <tt class="docutils literal"><span class="pre">sys.stdout</span></tt> and <tt class="docutils literal"><span class="pre">sys.stderr</span></tt> are used in the context of the
thread handling a request, calls against them to log messages will be
routed back via <tt class="docutils literal"><span class="pre">wsgi.errors</span></tt> from the per request WSGI <tt class="docutils literal"><span class="pre">environ</span></tt>
dictionary. This avoids the danger of logged messages from different
request handlers being intermixed as buffering will now be done on a per
request basis. Such messages will also be logged with the correct
connection and request log ID if the <tt class="docutils literal"><span class="pre">%L</span></tt> formatter is used in the
error log format.</li>

<li>Added new option <tt class="docutils literal"><span class="pre">--error-log-format</span></tt> to <tt class="docutils literal"><span class="pre">mod_wsgi-express</span></tt> to allow

<li>Pass through to the WSGI per request <tt class="docutils literal"><span class="pre">environ</span></tt> dictionary new values
for <tt class="docutils literal"><span class="pre">mod_wsgi.connection_id</span></tt> and <tt class="docutils literal"><span class="pre">mod_wsgi.request_id</span></tt>. These are
the Apache log IDs for the connection and request that it uses in log
