title: Spyder does not update to V4
body: <p>Updating spyder does nothing. My system is still stuck on V3. Can someone help me get this onto V4 please?</p>
  
  <p>I start the Anaconda navigator.</p>
  
  <p>I start Spyder V3.3.6</p>
  
  <p>A prompt informs me that Spyder 4.0.1 is available.</p>
  
  <p>I follow the instructions at : <a href="https://docs.spyder-ide.org/installation.html" rel="noreferrer">https://docs.spyder-ide.org/installation.html</a></p>
  
  <p>Open an Anaconda command window and type: conda update spyder</p>
  
  <p>Get the following:</p>
  
  <pre><code>(base) C:\Users\user&gt;conda update spyder

  Updating spyder is constricted by
  
  anaconda -&gt; requires spyder==3.3.6=py37_0
  
  If you are sure you want an update of your package either try `conda update --all` or install a specific version of the package you want using `conda install &lt;pkg&gt;=&lt;version&gt;`
  
  done
  
  # All requested packages already installed.
