title: Why matplotlib doesn't update in Anaconda to the 2.0 version
body: <p>I was lately trying to update all my Anaconda packages:</p>
  
  <pre><code>conda update conda
  conda update anaconda
  </code></pre>
  
  <p>Some of them still were not updated, so I also did <code>conda update --all</code>.
  Right now my <code>conda version : 4.3.16</code>, which seems to be the latest release. However, for some reason, matplotlib still has old version:</p>
  
  <pre><code>conda list
  matplotlib                1.5.1               np111py35_0 
  </code></pre>
  
  <p>According to the <a href="https://docs.continuum.io/anaconda/changelog" rel="noreferrer">Anaconda changelog</a>, it should be updated to 2.0 version: <code>matplotlib from 1.5.3 to 2.0.0</code>. 
  My installed python version is <code>3.5.2</code>, if this matters.</p>
  
  <p><strong>UPD</strong>: Seems that spyder-app is blocking update because of problem with dependencies:</p>
  
  <pre><code> conda install anaconda=4.3.1
  UnsatisfiableError: The following specifications were found to be in conflict:
    - anaconda 4.3.1* -&gt; spyder 3.1.2 py34_0
    - spyder-app -&gt; spyder 2.3.3
  Use "conda info &lt;package&gt;" to see the dependencies for each package.
  
  conda install matplotlib=2
  UnsatisfiableError: The following specifications were found to be in conflict:
   - matplotlib 2.0*
   - spyder-app -&gt; spyder 2.3.0 -&gt; pyqt 4.* -&gt; qt &gt;=4.8.6,&lt;5.0
   - spyder-app -&gt; spyder 2.3.0 -&gt; pyqt 4.* -&gt; sip &gt;=4.16.4,&lt;4.18
   Use "conda info &lt;package&gt;" to see the dependencies for each package.
  </code></pre>
  
  <p><strong>UPD2</strong>: Problem was solved by removing spyder-app:</p>
  
  <pre><code>conda remove spyder-app
  conda update anaconda
  </code></pre>
  
  <p>Matlotlib was updated to the 2.0 version, among other updated packages. I also checked if Spyder IDE still works, and it still is able to run.</p>
