V0.5 (25 February 98)
=====================
Portability aids, bug fixes and other improvements from several contributors:

- JPEG images could be closed multiply (p_jpeg.c)
- Introduce Mac and Win32 porting defs (p_port.h)
- Use define for path separator which is needed for the Mac's ":"
  (p_port.h, p_font.h)
- Rename structure member private to private_data for C++ compatibility
  (pdf.h, p_font.c, p_gif.c, p_jpeg.c, p_tiff.c)
- NeXT portability: include libc.h (imagepdf.c, pdfclock.c, pdfgraph.c, 
  text2pdf.c)
- Don't use malloc.h (afmparse.c)
- Change variable handling in make build process (makefile)
- Fix bug in octal character representation (p_text.c)
- Introduce word and character spacing functions (p_text.c)
- Fix subtle bug in font embedding: fonts with additional data after
  the zeros portion were not properly embedded (p_font.c)

Environment bindings:
- Introduces BINDINGS directory which will collect several language and
  environment bindings for PDFlib.
- Sample CGI script for the PDFclock example (BINDINGS/CGI/clock.cgi)

Several bugfixes, due to Detlev Droege's comments after
testing with his PDFviewer:

- Avoid empty /Filter arrays for uncompressed binary images (p_image.c).
- Change erroneous number of color components in demo page (pdfdemo.c).
- Implement consistency check for color components vs. color space
  (p_image.c)
- Write binary magic number for all files (ASCII and binary) (p_basic.c).
- Change "Producer" to "Creator" in sample application (hello.c).
- AFM handler crashed in case the AFM parser gave up on certain AFMs (p_font.c).
- AFM parser didn't correctly handle newer version 4.0 AFMs (afmparse.c).
- Use AFM 4.0 key "StdVW" for a more accurate /StemV in font descriptor 
  (p_font.c).
- API CHANGE: Change RGB parameters from byte to float since
  gray values are float parameters too (p_color.c).


V0.4 (8 September 97)
=====================
First public release.

- Generating multiple PDFs with embedded images resulted in wrong
  XObject numbers for the second and following PDFs. Use image_number
  from the PDF structure instead of a static variable.
  (p_image.c, p_basic.c)
- Makefile for Watcom C 10.6 included in the distribution, support
  Windows build (makefile.wat).
