<h2>4.0 (17 June 2018)<a class="headerlink" href="#june-2018" title="Permalink to this headline">¶</a></h2>
<p>Breaking changes:</p>
<blockquote>
<div><ul class="simple">
<li>This release drops support for Python 2.6. (<a class="reference external" href="https://github.com/gcovr/gcovr/issues/250">#250</a>)</li>
<li>PIP is the only supported installation method.</li>
<li>No longer encoding-agnostic under Python 2.7.
If your source files do not use the system encoding (probably UTF-8),
you will have to specify a --source-encoding.
(<a class="reference external" href="https://github.com/gcovr/gcovr/issues/148">#148</a>, <a class="reference external" href="https://github.com/gcovr/gcovr/issues/156">#156</a>, <a class="reference external" href="https://github.com/gcovr/gcovr/issues/256">#256</a>)</li>
<li>Filters now use forward slashes as path separators, even on Windows.
(<a class="reference external" href="https://github.com/gcovr/gcovr/issues/191">#191</a>, <a class="reference external" href="https://github.com/gcovr/gcovr/issues/257">#257</a>)</li>
<li>Filters are no longer normalized into pseudo-paths.
This could change the interpretation of filters in some edge cases.</li>
</ul>
</div></blockquote>

<blockquote>
<div><ul class="simple">
<li>Added a test driver for gcovr.</li>
<li>Improved estimation of the <code class="docutils literal notranslate"><span class="pre"><sources></span></code> element when using gcovr with filters.</li>
<li>Added revision and date keywords to gcovr so it is easier to identify
what version of the script users are using (especially when they are
running a snapshot from trunk).</li>
<li>Addressed special case mentioned in [comment:ticket:3884:1]: do not
truncate the reported file name if the filter does not start matching
at the beginning of the string.</li>
<li>Overhaul of the <code class="docutils literal notranslate"><span class="pre">--root</span></code> / <code class="docutils literal notranslate"><span class="pre">--filter</span></code> logic. This should resolve the
issue raised in #3884, along with the more general filter issue
raised in [comment:ticket:3884:1]</li>
<li>Overhaul of gcovr’s logic for determining gcc/g++’s original working
directory. This resolves issues introduced in the original
implementation of <code class="docutils literal notranslate"><span class="pre">--object-directory</span></code> (#3872, #3883).</li>
<li>Bugfix: gcovr was only including a <code class="docutils literal notranslate"><span class="pre"><sources></span></code> element in the XML
report if the user specified <code class="docutils literal notranslate"><span class="pre">-r</span></code> (#3869)</li>
<li>Adding timestamp and version attributes to the gcovr XML report (see
#3877). It looks like the standard Cobertura output reports number of
seconds since the epoch for the timestamp and a doted decimal version
string. Now, gcovr reports seconds since the epoch and
“<code class="docutils literal notranslate"><span class="pre">gcovr</span> <span class="pre">``"+``__version__</span></code> (e.g. “gcovr 2.2”) to differentiate it
from a pure Cobertura report.</li>
