title: How can I version bump all my dependencies?
body: <p>Having <code>yarn outdated</code> is quite informative but I'd like to avoid running over package by package doing <code>yarn upgrade</code>.</p>
  
  <p>From yarn's documentation, just <code>yarn upgrade</code> without arguments is said to upgrade all dependencies but there's no change in my project's <code>package.json</code> and <code>yarn outdated</code> shows the same packages versions than before.</p>
  
  <p>Is there some command or argument that just bumps all my dependencies?</p>
  
  <p>If not, is the practice discouraged in some way?</p>
