                <p>Apache OpenWhisk uses semantic versioning. Version numbers
                  use the form <code>major.minor.incremental-build</code> and
                  are incremented as follows:</p>
                    <ul>
                      <li><em>major version</em>: for incompatible API changes.</li>
                      <li><em>minor version</em>: for new functionality added in a backward-compatible manner.</li>
                      <li><em>incremental version</em>: for forward-compatible bug fixes.</li>
                      <li><em>build</em>: optional postfix to distinguish intermediate builds.</li>

                <h4>Unified Releases</h4>
                <p>A complete OpenWhisk system combines a number of
                   software components including action runtimes, CLI
                   tools, the core platform, the package catalog,
                   event providers, and deployment packaging. The
                   project makes periodic time-based unified releases
                   that bundle a compatible set of OpenWhisk's individually
                   released software components to make it easier for
                   users to install a coherent and complete OpenWhisk
                   system on their own machines.</p>
                <p>The available unified releases are:

                           We have not made a post-incubation release of this package yet.
                           Hide the download until we do.  The old one is not really usable (NodeJS 6 based)
                           and was removed from the downloads section a while ago.

          <h3>Developer Builds</h3>
          <p>Most of the Apache OpenWhisk project component repositories
            are configured within GitHub to automatically generate interim
            builds (not
            <a href="#apache-releases">official release builds</a>)
            for each merged Pull Request (PR) and/or on
            a nightly basis.  These builds, by default, are tagged
            <b><em>'nightly'</em></b> and appear under their respective GitHub
            component's release tab and are intended for developer
            evaluation and testing only.
          </p>
          <p>In some special cases,
            Committers on the project may choose to use GitHub to tag
            certain builds as they become closer to being Release Candidate
            (RC) builds.  However, <em>any build tagged within GitHub with
            either 'nightly' or any other tag <strong>do NOT have
            official Apache project release status</strong>.</em>
            All official Apache OpenWhisk release builds
            undergo a rigorous process to be approved and are linked
            <a style="font-weight:normal;" href="#apache-releases">above</a>.
          </p>
          <p>To be clear, <strong>GitHub "releases" are not official
            Apache OpenWhisk project releases.</strong>
