v2: - some great rewords from John
    - link to the stable contribute guide

    Note that I am not quite sure how the specific release date to be
    added in the Scheduling section. Something like following?

        <p>17.05
        <ul>
                <li>Proposal deadline: February 26
                <li>Integration deadline: March 30
                <li>Release: May 2

                <li>v17.02.1 Release: May 17
                <li>v16.11.2 Release: May 17
        </ul>
