Changes since the last public release (1.0.11):
Changes since the last public release (1.0.12):
Test for Windows platform in pngconf.h when including malloc.h (Emmanuel Blot)
Updated makefile.cygwin and handling of Cygwin's ALL_STATIC in pngconf.h
Added some never-to-be-executed code in pnggccrd.c to quiet compiler warnings.
Enabled PNG_MNG_FEATURES_SUPPORTED and enabled PNG_ASSEMBLER_CODE_SUPPORTED
by default.
Added runtime selection of MMX features.
Added png_set_strip_error_numbers function and related macros.
Added a check for attempts to read or write PLTE in grayscale PNG datastreams.
Eliminated the png_error about apps using png_read|write_init(). Instead,
libpng will reallocate the png_struct and info_struct if they are too small.
This retains future binary compatibility for old applications written for
libpng-0.88 and earlier.
Enabled user memory function by default.
Modified png_create_struct so it passes user mem_ptr to user memory allocator.
Increased png_mng_features flag from png_byte to png_uint_32.
Bumped shared-library (so-number) and dll-number to 3.
Updated contrib/gregbook
Updated makefile.ibmc
Added some typecasts to eliminate gcc 3.0 warnings. Changed prototypes
of png_write_oFFS width and height from png_uint_32 to png_int_32.
Updated example.c
Revised prototypes for png_debug_malloc and png_debug_free in pngtest.c
