   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.  
14    
15  - The branch tag color and font can now be set separately using branch_tag_*  - Implement new option to generate proper maps for different levels of HTML.
16    configuration options.    The option -x[34x] determines HTML 3.x (default), HTML 4.x or XHTML style
17      maps.
18    
19    - Implement a scheme to visualize merges based on tag names. If tags are
20      consistently named at the mergepoint and the destination, then these points
21      can be detected using regular expressions. Several new configuration
22      options, merge_*, describe the tags.
23    
24    - Implemented HTMLizing of expansion with %(...%). This prevents a possible
25      cross site scripting exploit when you use '<', '>' or '"' in tagnames.
26      This is a remote chance (you must be stupid to use these characters in a
27      tagname) but anyway, your system can be under attack.
28    
29    - Fixed backing up in the lexer. This improves speed slightly because no
30      rule requires lookahead over one character anymore.
31    
32    - Fixed a bug in the initial placing of left to right displaying.
33    
34    - Half-fixed a bug in the kerning code, where a loop-safeguard was triggered
35      way too soon (at 100 iterations). This has now been changed to 10000, but
36      should be dependent on the number of drawable branches, as the function is
37      _at least_ order O(N^2). However, more analysis is required to ensure
38      safe guarding under all circumstances.
39    
40    - Implemented folding of empty branches. Many uses of CVS create many
41      branches on the same revision but have no commits on them. This occurs
42      often with stable files like .cvsignore files and the like. A new
43      configuration option branch_fold enables imaging consequtive brances
44      with no commits in the same branch-box. This reduces images by a huge
45      factor (28000x1700 -> 2100x2300, i.e. a factor of 10). It also speeds up
46      drawing considerably. The branch_fold option is *on* by default.
47    
48    - Fix duplicate branch-boxes (branch_dupbox=true). No duplicates should be
49      created if there are no commits on a specific branch. There is no reason
50      for having two boxes on top of each other.
51    
52    - Implement folding for all branches on the same branchpoint if empty. New
53      option branch_foldall controls this behavior. See cvsgraph.conf(5) for
54      details. The imagemap is configured to map all branches within the box.
