187    <para>
188      The current HarfBuzz codebase is versioned 2.x.x and is stable
189      and under active maintenance. This is what is used in latest
190      versions of Firefox, GNOME, ChromeOS, Chrome, LibreOffice,
191      XeTeX, Android, and KDE, among other places.
192    </para>
193    <para>
194      Prior to 2012, the original HarfBuzz codebase (which, these days, is
195      referred to as <emphasis>harfbuzz-old</emphasis>) was derived from code
196      in <ulink url="http://freetype.org/">FreeType</ulink>,
197      <ulink url="http://pango.org/">Pango</ulink>, and
198      <ulink url="http://qt-project.org/">Qt</ulink>.
199      It is <emphasis>not</emphasis> actively developed or  maintained, and is
200      extremely buggy. All users of harfbuzz-old are encouraged to switch over
201      to the new HarfBuzz as soon as possible.
202    </para>
203    <para>
204      To make this distinction clearer in discussions, the current HarfBuzz
205      codebase is sometimes referred to as <emphasis>harfbuzz-ng</emphasis>.
206    </para>
207    <para>
208      For reference purposes, the harfbuzz-old source tree is archived
209      <ulink url="http://cgit.freedesktop.org/harfbuzz.old/">here</ulink>.
210      There are no release tarballs of harfbuzz-old whatsoever.
