 - Implement a workaround for browsers that do not understand unordered  
   y-coordinates in the imagemap when generated upside down.  
13    
14  - Fix the slowness of CvsGraph when parsing very large (typically -kb files) by  - Minor textual fixes in the config manual page
   bypassing the parsing of the actual deltatext. On my machine (K6-2/500/256M  
   it makes a difference of 7.5s vs 0.04s on a 93MByte file, without counting  
   disk-overhead; with disk-overhead it takes 12.5s).  Downside is that the  
   logentry cannot be expanded if the file is not parsed in full (see below).  
   Use option parse_logs to enable log-expansions.  
   
 - Implemented logentry expansions using %l and %L. You must enable full parsing  
   (option parse_logs) for this to work.  
   
 - Fixed a possible buffer overflow in the string expansion. However, this is a  
   very low-risk overflow, since it will trash the heap and _not_ the stack.  
   Furthermore, you need to pass strings from CGI directly to cvsgraph without  
   any checks to come even close to trash the heap.  
   
 - Fixed a segfault on IRIX in the bsearch calls. These lookups could be called  
   with a NULL pointer and IRIX's libc doesn't like that.  
   
 - Implement left to right and right to left images. The entire tree can now be  
   drawn horizontally when option left_right is set. Using both left_right and  
   upside_down results in right to left images.  
   
 - Implement limits on how many tags are printed in a revision box using new  
   config parameter rev_maxtags. Ellipsis (...) are printed if the limit becomes  
   active.  
15    
16  - Changed the configure script to handle libraries more intelligently. This  - Do a better job at drawing merge lines
   should be able to handle static libraries better.

 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 However, the scripts are no longer maintained because ViewCVS has  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.

98      If you are interested in tag-management with respect to the correct branch
99      information, then I suggest that you take a look at the contribution from
100      Henrik Carlqvist. He submitted some server-side scripts that can manage tags
101      in a better fashion than cvs on its own.
