-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

+   libpng-1.6.31-*.asc (armored detached GPG signatures)
+
+Changes since the last public release (1.6.30):
+
+  Guard the definition of _POSIX_SOURCE in pngpriv.h (AIX already defines it;
+    bug report by Michael Felt).
+  Revised pngpriv.h to work around failure to compile arm/filter_neon.S
+    ("typedef" directive is unrecognized by the assembler). The problem
+    was introduced in libpng-1.6.30beta01.
+  Added "Requires: zlib" to libpng.pc.in (Pieter Neerincx).
+  Added special case for FreeBSD in arm/filter_neon.S (Maya Rashish).
+  Added instructions for disabling hardware optimizations in INSTALL.
+  Added "--enable-hardware-optimizations" configuration flag to enable
+    or disable all hardware optimizations with one flag.
+  Updated CMakeLists.txt to add INTEL_SSE and MIPS_MSA platforms.
+  Changed "int" to "png_size_t" in intel/filter_sse2.c to prevent
+    possible integer overflow (Bug report by John Bowler).
+  Quieted "declaration after statement" warnings in intel/filter_sse2.c.
+  Added scripts/makefile-linux-opt, which has hardware optimizations enabled.
+  Removed one of the GCC-7.1.0 'strict-overflow' warnings that result when
+    integers appear on both sides of a compare.  Worked around the others by
+    forcing the strict-overflow setting in the relevant functions to a level
+    where they are not reported (John Bowler).
+  Changed "FALL THROUGH" comments to "FALLTHROUGH" because GCC doesn't like
+    the space.
+  Worked around some C-style casts from (void*) because g++ 5.4.0 objects
+    to them.
+  Increased the buffer size for 'sprint' to pass the gcc 7.1.0 'sprint
+    overflow' check that is on by default with -Wall -Wextra.
+  Added eXIf chunk support.
+  Added a minimal eXIf chunk (with Orientation and FocalLengthIn35mmFilm
+    tags) to pngtest.png.
