-This is a public release of libpng, intended for use in production codes.

+Changes since the last public release (1.2.1):
- Revised makefile.std in contrib/pngminus
- Include background_1 in png_struct regardless of gamma support.
- Revised makefile.netbsd and makefile.macosx, added makefile.darwin.
- Revised example.c to provide more details about using row_callback().
- Added makefile.so9.
- Removed type casts from all NULLs, except for those appearing in function
- calls when PNG_NO_TYPECAST_NULL is defined.
- Simplified png_create_info_struct() and png_creat_struct_2().
- Added error message if png_write_info() was omitted.
- Changed typecast of "size" argument to png_size_t in pngmem.c calls to
- the user malloc_fn, to agree with the prototype in png.h
- Added a pop/push operation to pnggccrd.c, to preserve Eflag (Maxim Sobolev)
- Updated makefile.sgi to recognize LIBPATH and INCPATH.
- Updated various makefiles so "make clean" does not remove previous major
- version of the shared library.
- Added a pop/push operation to pngvcrd.c, to preserve Eflag.
- Always allocate 256-entry internal palette, hist, and trans arrays, to
- avoid out-of-bounds memory reference caused by invalid PNG datastreams.
- Added a check for prefix_length > data_length in iCCP chunk handler.
+version 1.2.2beta1 [February 22, 2002]
+ Fixed a bug with reading the length of iCCP profiles (Larry Reeves).
+ Revised makefile.linux, makefile.gcmmx, and makefile.sgi to generate
+ libpng.a, libpng12.so (not libpng.so.3), and libpng12/png.h (not png.h)
+ Revised makefile.darwin to remove "-undefined suppress" option.
+ Added checks for gamma and chromaticity values over 21474.83, which exceed
+ the limit for PNG unsigned 32-bit integers when encoded.
+ Revised calls to png_create_read_struct() and png_create_write_struct()
+ for simpler debugging.
+ Revised png_zalloc() so zlib handles errors (uses PNG_FLAG_MALLOC_NULL_MEM_OK)
