  25 Changes since the last public release (1.6.28):
  26
  27   Readded "include(GNUInstallDirs)" to CMakeLists.txt (Gianfranco Costamagna).
  28   Moved SSE2 optimization code into the main libpng source directory.
  29     Configure libpng with "configure --enable-intel-sse" or compile
  30     libpng with "-DPNG_INTEL_SSE" in CPPFLAGS to enable it.
  31   Simplified conditional compilation in pngvalid.c, for AIX (Michael Felt).
  32   Avoid conditional directives that break statements in pngrutil.c (Romero
  33     Malaquias)
  34   The contrib/examples/pngtopng.c recovery code was in the wrong "if"
  35     branches; the comments were correct.
  36   Added code for PowerPC VSX optimisation (Vadim Barkov).
  37   Avoid potential overflow of shift operations in png_do_expand() (Aaron Boxer).
  38   Change test ZLIB_VERNUM >= 0x1281 to ZLIB_VERNUM >= 0x1290 in pngrutil.c
  39     because Solaris 11 distributes zlib-1.2.8.f that is older than 1.2.8.1.
  40   Suppress clang warnings about implicit sign changes in png.c
