 - The entire tree can now be drawn upside-down. This is usefull if you have  
   many revisions in a trunk and want to see the latest first. The configuration  
   includes an option 'upside_down' with a boolean argument. You can override the  
   default value on the command-line with the '-u' switch, which will negate the  
   configured value.  
   The imagemap generation also supports this, so you will still be able to point  
   and shoot on and between the revisions.  
   
 - You can now instruct CvsGraph to ommit all revisions that are not tagged. This  
   is highly usefull for very large trees/trunks to reduce the produced image  
   size. Note that the first and the last revision in a trunk are not hidden.  
   A new configuration option 'strip_untagged' with boolean argument enables this  
   feature. Alternatively, the command-line provides option '-s' wich negates the  
   value set in the configuration file. You can also strip the first revision if  
   it is untagged using '-S' and/or strip_first_rev.  
   
 - The boxes to identify the branches can now be drawn on both sides of the trunk.  
   Configuration option 'branch_dupbox' with boolean argument activates this  
   feature, which is usefull when the tree is drawn upside-down.The command-line  
   option '-b' negated the configured value.  
   
 - Configuration no longer requires a configuration file. All options can now be  
   entered on the commandline using '-O'. CvsGraph will still read the  
   configuration file if one is avaliable, but it is no longer an error if none  
   is found.  
   
 - If no file is entered on the command-line, then the input is taken from  
   standard input, like all decent *nix programs.  
   
 - 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 :-)  
   
 - Implemented string drawing using freetype interface of libgd. It looks very  
   nice, but it is significantly slower than gd's standard bitmap fonts. Extra  
   configuration parameters *_ttfont and *_ttsize set font and size. Option  
   use_ttf enables ttf rendering. Note that gd's bitmap fonts are used as a  
   fallback in case where the ttfont contains errors or is not found.  
13    
14  - The branch tag color and font can now be set separately using branch_tag_*  - Add regex method for ignoring tags in the generation of the graph. Old trees
15    configuration options.    are overpolulated and this is a way to reduce it even further. New config
16      options tag_ignore, tag_nocase and tag_negate.

23    - The timezone variable does not seem to exist on Mac OSX. I have no clue how
24      to patch this yet.
25      Anyhow, the timezone problem is much worse, because it needs to be calculated
26      from the revision's commit-time and not the current timezone (Daylight saving
27      must be accounted for at commit's time, not current).

 Alternately, you can hack the 'cvsweb' package to call CvsGraph. There are  
 several scripts and patches available from the CvsGraph homepage (see below for  
 address). However, the scripts are no longer maintained because ViewCVS has  
 native support now.
