title: Anaconda won't update spyder 4
body: <p>I just installed Anaconda and haven't changed anything. When I start spyder3 it tells me spyder 4 is available. 
  So I decided to update it.
  I tried </p>
  
  <pre><code>conda update  --all
  
  conda update conda
  
  conda update spyder
  </code></pre>
  
  <p>. </p>
  
  <p>It all gave no errors, but when I start spyder it's all fine. I know this should work because I already did this in the past. 
  Every help very appreciated. </p>
