            Apache Polygene™ (Java Edition) is split in two downloads: sources and binaries. Both downloads are available in the <code>zip</code> and <code>tar.gz</code> formats. The source code is also available on <a href="https://github.com/apache/polygene-java" target="_blank">Github</a>.
        </p>
        <p>
            The source distributions contains the whole Apache Polygene™ (Java Edition) source tree.
            See the included <code>README</code> for build guidance.
        </p>
        <p>
            The binary distributions contains Apache Polygene™ (Java Edition) artifacts (classes, javadocs and sources jars), helpers to download all needed dependencies, plus a local copy of the whole documentation website including browsable javadoc.

        <h2>Versioning</h2>

        <p>Apache Polygene™ versioning tries to stick to;</p>
        <ul>
            <li>For changes in the 3rd version digit, for instance from 1.3.1 to 1.3.2, only bug fixes have occurred.</li>
            <li>For changes in the 2nd version digit, for instance from 1.3.1 to 1.4, more features have been added.</li>
            <li>For changes in the 1st version digit, for instance from 1.3.1 to 2.0, incompatibilities have been introduced.</li>
        </ul>
        <p>
            However, this will only be true for APIs.
            For SPIs and especially Runtimes, we reserve the right of incompatible changes between releases in the
            second digit.
        </p>
        <p>
            We reserve the right that these dependencies on other systems may change between releases.
            For instance, a change between 1.1 and 1.2 was that CGLib was dropped and replaced by ASM
            as a new dependency.
