  <p>...dumped in STDOUT every time your run a spring boot app?</p>
  
  <p>I switched all logging to ERROR in my logback.xml, but that did nothing:</p>
  
  <pre><code>&lt;root level="ERROR"&gt;
      &lt;appender-ref ref="STDOUT" /&gt;
  &lt;/root&gt;
  </code></pre>
  
  <p><strong>edit: It's not called a "Logo" in the documentation. The search-friendly-term is a "banner".</strong></p>
