<h1>Version 4.2.8<a class="headerlink" href="#version-4-2-8" title="Permalink to this headline">¶</a></h1>
<p>Version 4.2.8 of mod_wsgi can be obtained from:</p>

<div><a class="reference external" href="https://github.com/GrahamDumpleton/mod_wsgi/archive/4.2.8.tar.gz">https://github.com/GrahamDumpleton/mod_wsgi/archive/4.2.8.tar.gz</a></div></blockquote>

<h2>Known Issues<a class="headerlink" href="#known-issues" title="Permalink to this headline">¶</a></h2>
<p>1. The makefiles for building mod_wsgi on Windows are currently broken and
need updating. As most new changes relate to mod_wsgi daemon mode, which is
not supported under Windows, you should keep using the last available
binary for version 3.X on Windows instead.</p>
</div>
<div class="section" id="bugs-fixed">
<h2>Bugs Fixed<a class="headerlink" href="#bugs-fixed" title="Permalink to this headline">¶</a></h2>
<p>1. Disable feature for dumping stack traces on daemon process shutdown when
a timeout occurs when using Python prior to 2.5. This is because the C API
functions are not available in older Python versions.</p>
<p>2. If using Python 3.4 the minimum MacOS X version you can use is 10.8.
This needs to be inforced as Apache Runtime library has a definition in
header files which changes sizes from 10.7 to 10.8 and trying to compile
for compatability back to 10.6 as Python 3.4 tries to enforce, will cause
mod_wsgi daemon mode processes to crash at runtime.</p>
<p>3. Python 3.3+ pyvenv style virtual environments would not work with
mod_wsgi via the <tt class="docutils literal"><span class="pre">WSGIPythonHome</span></tt> directive or the <tt class="docutils literal"><span class="pre">home</span></tt> option to the
<tt class="docutils literal"><span class="pre">WSGIDaemonProcess</span></tt> directive. This is because the support in Python for
pyvenv will not work with embedded systems which set the equivalent of
<tt class="docutils literal"><span class="pre">PYTHONHOME</span></tt> via the Python C API.</p>
<p>The underlying problem in Python is described in issue:</p>
<blockquote>
<div><ul class="simple">
<li><a class="reference external" href="http://bugs.python.org/issue22213">http://bugs.python.org/issue22213</a></li>
</ul>
</div></blockquote>
<p>of the Python issue tracer.</p>
<p>To support both normal virtualenv style virtual environments and pyvenv
style virtual environments, the manner in which virtual environments are
setup by mod_wsgi has been changed. This has at this point only been done
on UNIX systems however, as it isn&#8217;t known at this point whether the same
trick will work on Windows systems.</p>
