18    The imagemap generation also supports this, so you will still be able to point

28  - The boxes to identify the branches can now be drawn on both sides of the trunk.

 - ViewCVS (http://viewcvs.sourceforge.net) is now officially supporting the use  
   of CvsGraph in their code as of version 0.8. So, no bad hacks needed anymore  
   to get it working, and it always looks nice :-)
