Based<br /> on the concept of a project object model (POM), Maven can manage a<br /> project’s build, reporting and documentation from a central piece of<br /> information.</p> <p>You can find out more about Apache Maven at <a href="https://maven.apache.org">https://maven.apache.org</a></p> <p>You can download the appropriate sources etc. from<br /> the <a href="https://maven.apache.org/download.cgi">download page</a></p> <p> </p> <p>We really value the contributions of these non committers, so this section is<br /> focused on those individuals. Descriptions of the issues fixed can be found at<br /> the <a href="#Details">end of these release notes</a>.</p> <p>Issue Reporters of this release:</p> <ul> <li>Benoit GUERIN</li> <li>Christian Schulte</li> <li>Elliotte Rusty Harold</li> <li>Falko Modler</li> <li>Francesco Chicchiriccò</li> <li>Guillaume Nodet,</li> <li>guofei</li> <li>Joseph Walton</li> <li>Louis Mills</li> <li>Mark

<p>None.</p> <h2>Overview about the changes</h2> <ul> <li> <p>This release focuses mostly performance improvements, better memory footprint, and less CPU usage.</p> </li> <li> <p>We are continuing to convert Maven Core to use JSR 330 annotations instead of Plexus<br /> (still not finished, see MNG-5577).</p> </li> <li> <p>New support for ‘release’ qualifier (see MNG-6655).</p> </li> <li> <p>The <code>toolchain.xml</code> file supports environment variables (see MNG-6665).</p> </li> </ul> <h2>User visible Changes</h2> <p><code>toolchain.xml</code> now supports usage of environment variables which looks like this:</p> <figure class='code'> <figcaption><span></span></figcaption> <div class="highlight"> <table> <tr> <td class="gutter"> <pre class="line-numbers"><span
