Previously, any exceptions raised in a user call back would bubble out
of the <code class="docutils literal notranslate"><span class="pre">process</span></code> method, which is typically in the GUI event
loop. Most GUI frameworks simple print the traceback to the screen
and continue as there is not always a clear method of getting the
exception back to the user. However PyQt5 now exits the process when
it receives an un-handled python exception in the event loop. Thus,

<h2>Path.intersects_bbox always treats the bounding box as filled<a class="headerlink" href="#path-intersects-bbox-always-treats-the-bounding-box-as-filled" title="Link to this heading">#</a></h2>
<p>Previously, when <code class="docutils literal notranslate"><span class="pre">Path.intersects_bbox</span></code> was called with <code class="docutils literal notranslate"><span class="pre">filled</span></code> set to
<code class="docutils literal notranslate"><span class="pre">False</span></code>, it would treat both the path and the bounding box as unfilled. This
behavior was not well documented and it is usually not the desired behavior,
since bounding boxes are used to represent more complex shapes located inside
the bounding box. This behavior has now been changed: when <code class="docutils literal notranslate"><span class="pre">filled</span></code> is
<code class="docutils literal notranslate"><span class="pre">False</span></code>, the path will be treated as unfilled, but the bounding box is still
treated as filled. The old behavior was arguably an implementation bug.</p>
<p>When <code class="docutils literal notranslate"><span class="pre">Path.intersects_bbox</span></code> is called with <code class="docutils literal notranslate"><span class="pre">filled</span></code> set to <code class="docutils literal notranslate"><span class="pre">True</span></code>

the old behavior is actually desired, the suggested workaround is to call

of windowing function values to be one. In Matplotlib and Numpy the
standard windowing functions are scaled to have maximum value of one,
which usually results in a sum of the order of n/2 for a n-point
signal. Thus the amplitude scaling <code class="docutils literal notranslate"><span class="pre">magnitude_spectrum()</span></code> was
off by that amount when using standard windowing functions (<a class="reference external" href="https://github.com/matplotlib/matplotlib/issues/8417">Bug 8417</a> ). Now the
