<h2>Bug Fixes<a class="headerlink" href="#bug-fixes" title="Permalink to this headline">¶</a></h2>
<p>1. A negative value for content length in response wasn&#8217;t being rejected.
Where invalid header was being returned in response original response
status was being returned instead of a 500 error.</p>
<p>2. Fix bug which was resulting in logging destined for !VirtualHost !ErrorLog
going missing or ending up in main Apache error log.</p>

<h2>Features Added<a class="headerlink" href="#features-added" title="Permalink to this headline">¶</a></h2>
<p>1. Optimise sending of WSGI environment across to daemon process by
reducing number of writes to socket. For daemon mode and a simple hello
world application this improves base performance by 40% moving it
significantly closer to performance of embedded mode.</p>
<p>This is a backport of change from version 2.0 of mod_wsgi.</p>
