Answers.Body: <p>I ran into this error when updating a live Craft site. My local update had gone fine. So I ended up editing my <code>craft/app/Info.php</code> file (live) from:</p>
  
  <pre><code>define('CRAFT_VERSION', '2.6');
  define('CRAFT_BUILD', '2949');
  </code></pre>
  
  <p>to just:</p>
  
  <pre><code>define('CRAFT_VERSION', '2.6.2949');
  </code></pre>
  
  <p>I then ran into the error:</p>
  
  <blockquote>
    <p>Internal Server Error Use of undefined constant CRAFT_MIN_VERSION_REQUIRED</p>
  </blockquote>
  
  <p>So again, I updated my <code>craft/app/Info.php</code> to add the line:</p>
  
  <pre><code>define('CRAFT_MIN_VERSION_REQUIRED', '2.1.2570');
  </code></pre>
  
  <p>It then logged me in and and asked me to finish updating SEOmatic, so I clicked <code>Update</code> and it was running fine again but showing the following depreciation errors:</p>
  
  <blockquote>
    <p>craft()->getBuild() has been deprecated. As of Craft 2.6.2951,
    craft()->getVersion() returns the complete version number
    (X.Y.Z).  /var/www/craft/app/etc/behaviors/AppBehavior.php (149)</p>

  Had a plugin installed which had been using CRAFT\_BUILD and as its been deprecated it was throwing the error, problem was could access admin to update plugin.
  
  Manually, entered CRAFT\_BUILD and other deprecated info into `craft/app/Info.php` and it let me login to fix.
