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