Added PNG_NO_ERROR_TEXT feature, with demo in contrib/pngminim Removed define PNG_WARN_UNINITIALIZED_ROW 1 /* 0: warning; 1: error */ because it caused some trouble. version 1.2.20beta02 [August 20, 2007] Avoid compiling pnggccrd.c on Intel-Apple platforms. version 1.2.20beta03 [August 20, 2007] Added "/D PNG_NO_MMX_CODE" to the non-mmx builds of projects/visualc6 and visualc71. version 1.2.20beta04 [August 21, 2007] Revised pngvcrd.c for improved efficiency (Steve Snyder). version 1.2.20rc1 [August 23, 2007] Revised pngconf.h to set PNG_NO_MMX_CODE for gcc-3.x compilers. version 1.2.20rc2 [August 27, 2007] Revised scripts/CMakeLists.txt Revised #ifdefs to ensure one and only one of pnggccrd.c, pngvcrd.c, or part of pngrutil.c is selected. version 1.2.20rc3 [September 1, 2007] Remove a little more code in pngwutil.c when PNG_NO_WRITE_FILTER is selected. Added /D _CRT_SECURE_NO_WARNINGS to visual6c and visualc71 projects. Compile png_mmx_support() in png.c even when PNG_NO_MMX_CODE is defined. Restored a "superfluous" #ifdef that was removed from 1.2.20rc2 pnggccrd.c, breaking the png_mmx_support() function. version 1.2.20rc4 [September 1, 2007] Removed Intel contributions (MMX, Optimized C).
