<h1>Upgrade a repo<a class="headerlink" href="#upgrade-a-repo" title="Permalink to this headline"></a></h1>
<p>In order to upgrade a previously installed repository, the “newt
upgrade” command should be issued:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>$ newt upgrade
</pre></div>
</div>
<p>Newt upgrade will look at the current desired version in
<code class="docutils literal notranslate"><span class="pre">project.yml</span></code>, and compare it to the version in <code class="docutils literal notranslate"><span class="pre">project.state</span></code>. If
these two differ, it will upgrade the dependency. Upgrade works not just
for the dependency in <code class="docutils literal notranslate"><span class="pre">project.yml</span></code>, but for all the sub-dependencies
that they might have.</p>
