   <span class="post-date-author">By Tomaz Muraus on Dec 09, 2019</span>

   <div class="post-content">
     <p>We are pleased to announce the release of Libcloud 2.7.0.</p>

 <p>Among various smaller bug fixes, this release also includes a couple of big
 new features.</p>

 <p>Highlights include:</p>

 <ul>
   <li>Initial type annotations / hints support for the base Libcloud compute API.</li>
   <li>S3 driver class has been updated to support <code class="language-plaintext highlighter-rouge">region</code> argument in the same
 manner as other drivers which support multiple regions (no more messy class
 per region approach). For backward compatibility reasons, “class per region”
 approach will still be supported until the next major release.</li>
   <li>New <code class="language-plaintext highlighter-rouge">start_node()</code> and <code class="language-plaintext highlighter-rouge">stop_node()</code> method have been added to the base
 Libcloud compute API and the existing drivers which implement
 <code class="language-plaintext highlighter-rouge">ex_start_node()</code> and <code class="language-plaintext highlighter-rouge">ex_stop_node()</code> methods have been updated to
 implement those new methods. Old <code class="language-plaintext highlighter-rouge">ex_</code> methods will continue to work for
 backward compatibility reasons.</li>
 </ul>

 <p>Full change log can be found at
 <a href="https://libcloud.readthedocs.io/en/latest/changelog.html#changes-in-apache-libcloud-v2-7-0">https://libcloud.readthedocs.io/en/latest/changelog.html#changes-in-apache-libcloud-v2-7-0</a>.</p>

 <h3 id="dropping-support-for-python-27-and-python-34">Dropping support for Python 2.7 and Python 3.4</h3>

 <p>Libcloud was among some of the other early larger Python projects which have
 supported Python 2.x and Python 3.x simultaneously using a single code base
 from 2011.</p>

 <p>Over the years, the landscape has changed a lot. A lot of the users now use
 Python 3 as a default and a lot of the popular Python projects now not only
 support Python 3, but also make Python 3 the only supported Python version.</p>

 <p>In addition to that, <a href="https://pythonclock.org/">Python 2.7 will not be maintained past January 2020</a>.</p>

 <p>We have decided to sign the <a href="https://python3statement.org/">Python 3 statement</a> and drop support for Python
 2.7 and Python 3.4 in the next major release (v3.0.0) which will coincide
 with Python 2.7 EOL early next year.</p>

 <p>This means that Libcloud v2.7.0 will be the last major release which still
 supports Python 2.7 and 3.4.</p>

 <p>The change itself is still work in progress. People who are interested in it
 can check the following PR <a href="https://github.com/apache/libcloud/pull/1377">https://github.com/apache/libcloud/pull/1377</a>.</p>

 <h4 id="how-does-this-affect-me">How does this affect me?</h4>

 <p>If you still need to use Python 2.7 or Python 3.4 after Libcloud v3.0.0 is
 out, you will be able to do that by utilizing one of the older Libcloud
 releases which still supports that Python version.</p>

 <p>All the new feature development and improvements will land in new release
 which support Python &gt;= 3.5 only, but we may still do a release in the
 v2.7.x release series if a major bug or a security issue is found.</p>

 <h4 id="how-does-this-affect-the-libcloud-development-team">How does this affect the Libcloud development team?</h4>

 <p>Supporting Python 2.x and Python 3.x through a single code base was never
 totally trivial.</p>

 <p>This is especially true for our project which doesn’t use <code class="language-plaintext highlighter-rouge">six</code> Python 2
 / 3 compatibility library, but uses custom glue / wrapper code for that.</p>

 <p>There are multiple reasons why we didn’t use <code class="language-plaintext highlighter-rouge">six</code> - one is that we still
 needed to support Python 2.5 which is not supported by <code class="language-plaintext highlighter-rouge">six</code> and another
 one is that we didn’t want to introduce another dependency on the end user in
 the days where Python packaging was still very much in the infancy.</p>

 <p>Dropping support for Python 2.7 and Python 3.4 will allow us to streamline our
 code and remove a lot of the code which is not needed anymore.</p>

 <p>This will result in easier development and cleaner code.</p>

 <h3 id="download">Download</h3>
