WenQuanYi Zen Hei ChangeLog:

2008/10/27  Qianqian Fang (fangqq#gmail_com) (Prayer 0.8.34.cvs20081027):
          1. more than 1000 characters were manually improved 
             since the last release (0.6) (by three-leg-cat)
          2. the ttc file size is only 11M with two font faces
          3. all missing (~760) CJK Extension A Hanzi now complete
             the phase of stroke decomposition and will be added
             to the font in the next major release

2008/09/06  Qianqian Fang (fangqq#gmail_com) (Prayer 0.8.34):
          1. added monospaced face, Zen Hei Mono, into the font
          2. font format was updated from ttf to ttc to reduce
             file sizes
          3. streamlining the ttc font creating in the nightly-
             build script.

2008/07/23  Qianqian Fang (fangqq#gmail_com) (Prayer 0.8.32):
          1. extracted the radical information from 17,000 Hanzis
             and modify the glyph generation script so that we could 
             use unified radical glyphs for all characters sharing
             the same radicals; this greatly improved the look and
             feel of the font
          2. performed more aggressive outline simplification to 
             reduce the font size
          3. hand-tunning the radical positions for 500 Hanzi
          4. all CJK Basic Hanzi (i.e. GBK, 20932 char.) were reviewed
             and make sure that their shape match the Chinese goverment 
             national standards (project BlueSky)

2008/06/20  Qianqian Fang (fangqq#gmail_com) (Prayer 0.6.26):
          1. corrected more than 10 bugs in the glyph generation

             HZG,SZZG,HZZZG,SWG,PN,TPN,WG,PD,D,N,PT
          3. automatically combine HG,SG if they follow
          4. more sophisticated algorithm for edge aligment and 
             margin calculation
          5. stroke thickness was slightly fine-tuned

2008/06/18  Qianqian Fang (fangqq#gmail_com) (Prayer 0.6.23):
          1. added vertical metrics
          2. fix wrong bitmap glyph advance under Windows

          3. fix incorrect reference mapping order for CJK Radical Supplement
             for blocks U2E9A-U2EB2 and U2EC0-U2EC1
          4. used the traditional forms for U2EEF and U2ECE, added U2EE1

          7. added GASP table
          8. thousands (precisely, 6749) of Hanzi glyphs were optimized and 
             updated based on the structures from National Standard GB18030
             (55% of CJK basic Hanzi has been reviewed so far)
          9. add Chinese font names in the fontconfig pattern match 
             in 44-wqy-zenhei.conf
         10. add 66-wqy-zenhei-sharp.conf for users who prefer bitmaps
         11. the TTF file size is 2.6M smaller than 0.5.23 ! even the
