34    - Configuration no longer requires a configuration file. All options can now be
35      entered on the commandline using '-O'. CvsGraph will still read the

37      is found.

46    - Implemented string drawing using freetype interface of libgd. It looks very
47      nice, but it is significantly slower than gd's standard bitmap fonts. Extra
48      configuration parameters *_ttfont and *_ttsize set font and size. Option
49      use_ttf enables ttf rendering. Note that gd's bitmap fonts are used as a
50      fallback in case where the ttfont contains errors or is not found.
51    
52    - The branch tag color and font can now be set separately using branch_tag_*
53      configuration options.
54    
55    - It is now possible to draw the connector lines between the boxes thicker
56      by setting thick_lines to something else than 1. Maximum thickness is
57      limited to lines of 11 pixels wide.
