13  - The entire tree can now be drawn upside-down. This is usefull if you have  
14    many revisions in a trunk and want to see the latest first. The configuration  - Add patch from Henrik Carlqvist <henca@users.SourceForge.net>
15    includes an option 'upside_down' with a boolean argument. You can override the          * add option rev_hidenumber for disabling revision number display.
16    default value on the command-line with the '-u' switch, which will negate the          * add option tag_ignore_merge for disabling merge_from/merge_to display
17    configured value.            if matched with tag_ignore.
18    The imagemap generation also supports this, so you will still be able to point  
19    and shoot on and between the revisions.  - Add option merge_findall so that merge_from/merge_to tags can have multiple
20      matches.
21  - You can now instruct CvsGraph to ommit all revisions that are not tagged. This  
22    is highly usefull for very large trees/trunks to reduce the produced image  
23    size. Note that the first and the last revision in a trunk are not hidden.  
24    A new configuration option 'strip_untagged' with boolean argument enables this  Known BUGS
25    feature. Alternatively, the command-line provides option '-s' wich negates the  ----------
26    value set in the configuration file. You can also strip the first revision if  
27    it is untagged using '-S' and/or strip_first_rev.  - The timezone variable does not seem to exist on Mac OSX. I have no clue how
28      to patch this yet.
29  - The boxes to identify the branches can now be drawn on both sides of the trunk.    Anyhow, the timezone problem is much worse, because it needs to be calculated
30    Configuration option 'branch_dupbox' with boolean argument activates this    from the revision's commit-time and not the current timezone (Daylight saving
31    feature, which is usefull when the tree is drawn upside-down.The command-line    must be accounted for at commit's time, not current).
32    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 :-)

 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.
