-Changes since the last public release (1.6.16):

-

-  Removed duplicate PNG_SAFE_LIMITS_SUPPORTED handling from pngconf.h

-  Corrected the width limit calculation in png_check_IHDR().

-  Removed user limits from pngfix. Also pass NULL pointers to

-    png_read_row to skip the unnecessary row de-interlace stuff.

-  Added testing of png_set_packing() to pngvalid.c

-  Regenerated configure scripts in the *.tar distributions with libtool-2.4.4

-  Implement previously untested cases of libpng transforms in pngvalid.c

-  Fixed byte order in 2-byte filler, in png_do_read_filler().

-  Made the check for out-of-range values in png_set_tRNS() detect

-    values that are exactly 2^bit_depth, and work on 16-bit platforms.

-  Merged some parts of libpng-1.6.17beta01 and libpng-1.7.0beta47.

-  Added #ifndef __COVERITY__ where needed in png.c, pngrutil.c and

-    pngset.c to avoid warnings about dead code.

-  Do not build png_product2() when it is unused.

-  Display user limits in the output from pngtest.

-  Eliminated the PNG_SAFE_LIMITS macro and restored the 1-million-column

-    and 1-million-row default limits in pnglibconf.dfa, that can be reset

-    by the user at build time or run time.  This provides a more robust

-    defense against DOS and as-yet undiscovered overflows.

-  Added PNG_WRITE_CUSTOMIZE_COMPRESSION_SUPPORTED macro, on by default.

-  Allow user to call png_get_IHDR() with NULL arguments (Reuben Hawkins).

-  Rebuilt configure scripts with automake-1.15 and libtool-2.4.6

-  Moved png_set_filter() prototype into a PNG_WRITE_SUPPORTED block

-    of png.h.

-  Avoid runtime checks when converting integer to png_byte with

-    Visual Studio (Sergey Kosarevsky)

-  Removed some comments that the configure script did not handle

-    properly from scripts/pnglibconf.dfa and pnglibconf.h.prebuilt.

-  Free the unknown_chunks structure even when it contains no data.

-  Updated CMakeLists.txt to add OSX framework, change YES/NO to ON/OFF

-    for consistency, and remove some useless tests (Alexey Petruchik).

-  Remove pnglibconf.h, pnglibconf.c, pnglibconf.pre, pnglibconf.dfn,

-    and pnglibconf.out instead of pnglibconf.* in "make clean" (Cosmin).

-  Fixed simplified 8-bit-linear to sRGB alpha. The calculated alpha

-    value was wrong.  It's not clear if this affected the final stored

-    value; in the obvious code path the upper and lower 8-bits of the

-    alpha value were identical and the alpha was truncated to 8-bits

-    rather than dividing by 257 (John Bowler).

+

+Changes since the last public release (1.6.28):

+

+  Readded "include(GNUInstallDirs)" to CMakeLists.txt (Gianfranco Costamagna).

+  Moved SSE2 optimization code into the main libpng source directory.

+    Configure libpng with "configure --enable-intel-sse" or compile

+    libpng with "-DPNG_INTEL_SSE" in CPPFLAGS to enable it.

+  Simplified conditional compilation in pngvalid.c, for AIX (Michael Felt).

+  Avoid conditional directives that break statements in pngrutil.c (Romero

+    Malaquias)

+  The contrib/examples/pngtopng.c recovery code was in the wrong "if"

+    branches; the comments were correct.

+  Added code for PowerPC VSX optimisation (Vadim Barkov).

+  Avoid potential overflow of shift operations in png_do_expand() (Aaron Boxer).

+  Change test ZLIB_VERNUM >= 0x1281 to ZLIB_VERNUM >= 0x1290 in pngrutil.c

+    because Solaris 11 distributes zlib-1.2.8.f that is older than 1.2.8.1.

+  Suppress clang warnings about implicit sign changes in png.c
