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