 - Fix warnings in readconf on some 'older' compiler systems.  
13    
14  - Implement new option to generate proper maps for different levels of HTML.  - Fix all numeric author ID
15    The option -x[34x] determines HTML 3.x (default), HTML 4.x or XHTML style  
16    maps.  - Changed acceptable mail policy. See below in this file
17    
18  - Implement a scheme to visualize merges based on tag names. If tags are  - Fix incomplete parsing of access keyword in rcsfile
19    consistently named at the mergepoint and the destination, then these points  
20    can be detected using regular expressions. Several new configuration  - Fix missing branch_bgcolor in manpage
21    options, merge_*, describe the tags.  
22    - Fix author names with spaces but not in @ encapsulation
23  - Implemented HTMLizing of expansion with %(...%). This prevents a possible  
24    cross site scripting exploit when you use '<', '>' or '"' in tagnames.  - Added multiple merge_{from,to,color} matching. Now several regex

26    tagname) but anyway, your system can be under attack.  
27    - Added dynamic colors and strings for more flexibility in visual
28  - Fixed backing up in the lexer. This improves speed slightly because no    representations of the tree.
29    rule requires lookahead over one character anymore.  
30    - Added keyword rev_idtext to define the revision ID in a revision
31  - Fixed a bug in the initial placing of left to right displaying.    box. Normally this would show the revision number, but can now be
32      changed dynamically.
33  - Half-fixed a bug in the kerning code, where a loop-safeguard was triggered  
34    way too soon (at 100 iterations). This has now been changed to 10000, but  - Fix dashed lines when stripped revisions have mergepoints attatched
   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.

 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.

115    - contrib/automatic_documentation:
116      If you are interested in tag-management with respect to the correct branch
117      information, then I suggest that you take a look at the contribution from
118      Henrik Carlqvist. He submitted some server-side scripts that can manage tags
119      in a better fashion than cvs on its own.
