 - Fix warnings in readconf on some 'older' compiler systems.  
13    
14  - Implement new option to generate proper maps for different levels of HTML.  - Fix POSIX compliance in timezone handling. Only putenv() is used now.
15    The option -x[34x] determines HTML 3.x (default), HTML 4.x or XHTML style  
16    maps.  - Fix branch-count when branches get folded.
17    
18  - Implement a scheme to visualize merges based on tag names. If tags are  - Fix configure script to detect gd-2 problems (Thanks to Russell Yanofsky)

20    can be detected using regular expressions. Several new configuration  - Work around CVSNT wrong keyword ordering breaking rcsfile(5) ordering
21    options, merge_*, describe the tags.  
22    - Fix complaining about a new CVSNT keyword properties
23  - Implemented HTMLizing of expansion with %(...%). This prevents a possible  
24    cross site scripting exploit when you use '<', '>' or '"' in tagnames.  - Fix mergepoint1 syntax used by CVSNT allowing revision numbers as argument
   This is a remote chance (you must be stupid to use these characters in a  
   tagname) but anyway, your system can be under attack.  
   
 - Fixed backing up in the lexer. This improves speed slightly because no  
   rule requires lookahead over one character anymore.  
   
 - Fixed a bug in the initial placing of left to right displaying.  
   
 - Half-fixed a bug in the kerning code, where a loop-safeguard was triggered  
   way too soon (at 100 iterations). This has now been changed to 10000, but  
   should be dependent on the number of drawable branches, as the function is  
   _at least_ order O(N^2). However, more analysis is required to ensure  
   safe guarding under all circumstances.  
   
 - Implemented folding of empty branches. Many uses of CVS create many  
   branches on the same revision but have no commits on them. This occurs  
   often with stable files like .cvsignore files and the like. A new  
   configuration option branch_fold enables imaging consequtive brances  
   with no commits in the same branch-box. This reduces images by a huge  
   factor (28000x1700 -> 2100x2300, i.e. a factor of 10). It also speeds up  
   drawing considerably. The branch_fold option is *on* by default.  
   
 - Fix duplicate branch-boxes (branch_dupbox=true). No duplicates should be  
   created if there are no commits on a specific branch. There is no reason  
   for having two boxes on top of each other.  
   
 - Implement folding for all branches on the same branchpoint if empty. New  
   option branch_foldall controls this behavior. See cvsgraph.conf(5) for  
   details. The imagemap is configured to map all branches within the box.

 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.

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