Changes since the last public release (1.5.9):

Version 1.5.10beta01 [February 24, 2012]
  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.

Version 1.5.10beta02 [February 27, 2012]
  Updated Makefile.in

Version 1.5.10beta03 [March 6, 2012]
  Removed unused "current_text" members of png_struct and the png_free()
    of png_ptr->current_text from pngread.c
  Added palette-index checking.

Version 1.5.10beta04 [March 10, 2012]
  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.
