Changes since the last public release (1.5.9):
Removed two useless #ifdef directives from pngread.c and one from pngrutil.c
Always put the CMAKE_LIBRARY in "lib" (removed special WIN32 case).
Removed empty vstudio/pngstest directory (Clifford Yapp).
Eliminated redundant png_push_read_tEXt|zTXt|iTXt|unknown code from
pngpread.c and use the sequential png_handle_tEXt, etc., in pngrutil.c;
now that png_ptr->buffer is inaccessible to applications, the special
handling is no longer useful.
Fixed bug with png_handle_hIST with odd chunk length (Frank Busse).
Added PNG_SAFE_LIMITS feature to pnglibconf.dfa and code in pngconf.h
to reset the user limits to safe ones if PNG_SAFE_LIMITS is defined.
To enable, use "CPPFLAGS=-DPNG_SAFE_LIMITS_SUPPORTED" on the configure
command or put "#define PNG_SAFE_LIMITS_SUPPORTED" in pnglibconf.h.
Revised the SAFE_LIMITS feature to be the same as the feature in libpng16.
Added information about the new limits in the manual.
Updated Makefile.in
Removed unused "current_text" members of png_struct and the png_free()
of png_ptr->current_text from pngread.c
Fixed PNG_LIBPNG_BUILD_BASE_TYPE definition.
Fixed CMF optimization of non-IDAT compressed chunks, which was added at
libpng-1.5.4. It sometimes produced too small of a window.
Reject all iCCP chunks after the first, even if the first one is invalid.
Added palette-index checking. Issue a png_benign_error() if an invalid
index is found.
Revised example.c to put text strings in a temporary character array
instead of directly assigning string constants to png_textp members.
This avoids compiler warnings when -Wwrite-strings is enabled.
Prevent PNG_EXPAND+PNG_SHIFT doing the shift twice.
Revised png_set_text_2() to avoid potential memory corruption (fixes
CVE-2011-3048).
