  <note>
    <para>
      The current HarfBuzz codebase is versioned 2.x.x and is stable
      and under active maintenance. This is what is used in latest
      versions of Firefox, GNOME, ChromeOS, Chrome, LibreOffice,
      XeTeX, Android, and KDE, among other places.
    </para>
    <para>
      Prior to 2012, the original HarfBuzz codebase (which, these days, is
      referred to as <emphasis>harfbuzz-old</emphasis>) was derived from code
      in <ulink url="http://freetype.org/">FreeType</ulink>,
      <ulink url="http://pango.org/">Pango</ulink>, and
      <ulink url="http://qt-project.org/">Qt</ulink>.
      It is <emphasis>not</emphasis> actively developed or  maintained, and is
      extremely buggy. All users of harfbuzz-old are encouraged to switch over
      to the new HarfBuzz as soon as possible.
    </para>
    <para>
      To make this distinction clearer in discussions, the current HarfBuzz
      codebase is sometimes referred to as <emphasis>harfbuzz-ng</emphasis>.
    </para>
    <para>
      For reference purposes, the harfbuzz-old source tree is archived

      There are no release tarballs of harfbuzz-old whatsoever.
