Released 2004 April 15

moved web pages from cs.berkeley.edu to multivalent.sourceforge.net
license changed to GPL
PDF
- workarounds for buggy PDF generators
  - Ghostscript 5.x bug in generating inline images where Height is too big
  - FOP 0.20.3 inserts the Tc PDF operator in the middle of the TJ operator
- font tuning: spacing, baseline tracking, character unencoded by embedded PDF encoding uses font's intrinsic encoding, find X11 fonts, find Windows CJK fonts, better shaping of old OS9 fonts on OS X
- refinements on images: 4 bits per sample, Fax where /Width != /Columns
Tools
- ExtractText: further tuned word identification (from PDF's letter clusters)
- Compress and Uncompress were affected by the Ghostscript bug above

Released 2005 December 31
