 - Fix warnings in readconf on some 'older' compiler systems.  
13    
14  - Implement new option to generate proper maps for different levels of HTML.  - Add patch from Henrik Carlqvist <henca@users.SourceForge.net>
15    The option -x[34x] determines HTML 3.x (default), HTML 4.x or XHTML style          * add option rev_hidenumber for disabling revision number display.
16    maps.          * add option tag_ignore_merge for disabling merge_from/merge_to display
17              if matched with tag_ignore.
18  - Implement a scheme to visualize merges based on tag names. If tags are  
19    consistently named at the mergepoint and the destination, then these points  - Add option merge_findall so that merge_from/merge_to tags can have multiple
20    can be detected using regular expressions. Several new configuration    matches.
21    options, merge_*, describe the tags.  
22    
23  - Implemented HTMLizing of expansion with %(...%). This prevents a possible  
24    cross site scripting exploit when you use '<', '>' or '"' in tagnames.  Known BUGS
25    This is a remote chance (you must be stupid to use these characters in a  ----------
26    tagname) but anyway, your system can be under attack.  
27    - The timezone variable does not seem to exist on Mac OSX. I have no clue how
28  - Fixed backing up in the lexer. This improves speed slightly because no    to patch this yet.
29    rule requires lookahead over one character anymore.    Anyhow, the timezone problem is much worse, because it needs to be calculated
30      from the revision's commit-time and not the current timezone (Daylight saving
31  - Fixed a bug in the initial placing of left to right displaying.    must be accounted for at commit's time, not current).
   
 - 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.

 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.
