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).
Version 1.6.29beta02 [February 22, 2017]
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).
Version 1.6.29beta03 [March 1, 2017]
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,
as suggested in zlib FAQ, item 24.
Suppress clang warnings about implicit sign changes in png.c
Version 1.6.29 [March 16, 2017]
No changes.
Version 1.6.30beta01 [April 1, 2017]
Added missing "$(CPPFLAGS)" to the compile line for c.pic.o in
makefile.linux and makefile.solaris-x86 (Cosmin).

Document need to check for integer overflow when allocating a pixel
buffer for multiple rows in contrib/gregbook, contrib/pngminus,
example.c, and in the manual (suggested by Jaeseung Choi). This
is similar to the bug reported against pngquant in CVE-2016-5735.

Version 1.6.30rc02 [June 25, 2017]
Update copyright year in pnglibconf.h, make ltmain.sh executable.
Add a reference to the libpng.download site in README.
Version 1.6.30 [June 28, 2017]
No changes.
Version 1.6.31beta01 [July 5, 2017]
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

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.
Version 1.6.31beta04 [July 11, 2017]
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.
Version 1.6.31beta05 [July 13, 2017]
Added eXIf chunk support.
Version 1.6.31beta06 [July 17, 2017]
Added a minimal eXIf chunk (with Orientation and FocalLengthIn35mmFilm
tags) to pngtest.png.
Version 1.6.31beta07 [July 18, 2017]
Revised the eXIf chunk in pngtest.png to fix "Bad IFD1 Directory" warning.

report by John Smith)
Version 1.6.31 [July 27, 2017]
No changes.
Version 1.6.32beta01 [July 31, 2017]
Avoid possible NULL dereference in png_handle_eXIf when benign_errors
are allowed. Avoid leaking the input buffer "eXIf_buf".
Eliminated png_ptr->num_exif member from pngstruct.h and added num_exif
to arguments for png_get_eXIf() and png_set_eXIf().
Added calls to png_handle_eXIf(() in pngread.c and png_write_eXIf() in
pngwrite.c, and made various other fixes to png_write_eXIf().
Changed name of png_get_eXIF and png_set_eXIf() to png_get_eXIf_1() and
png_set_eXIf_1(), respectively, to avoid breaking API compatibility
with libpng-1.6.31.
Version 1.6.32beta02 [August 1, 2017]
Updated contrib/libtests/pngunknown.c with eXIf chunk.
Version 1.6.32beta03 [August 2, 2017]

Update libpng.3 and libpng-manual.txt about eXIf functions.
Version 1.6.32beta05 [August 2, 2017]
Restored png_get_eXIf() and png_set_eXIf() to maintain API compatibility.
Version 1.6.32beta06 [August 2, 2017]
Removed png_get_eXIf_1() and png_set_eXIf_1().
Version 1.6.32beta07 [August 3, 2017]
Check length of all chunks except IDAT against user limit to fix an
OSS-fuzz issue (Fixes CVE-2017-12652).
Version 1.6.32beta08 [August 3, 2017]
Check length of IDAT against maximum possible IDAT size, accounting
for height, rowbytes, interlacing and zlib/deflate overhead.
Restored png_get_eXIf_1() and png_set_eXIf_1(), because strlen(eXIf_buf)
does not work (the eXIf chunk data can contain zeroes).
Version 1.6.32beta09 [August 3, 2017]
Require cmake-2.8.8 in CMakeLists.txt. Revised symlink creation,
no longer using deprecated cmake LOCATION feature (Clifford Yapp).
Fixed five-byte error in the calculation of IDAT maximum possible size.
Version 1.6.32beta10 [August 5, 2017]
Moved chunk-length check into a png_check_chunk_length() private
function (Suggested by Max Stepin).
Moved bad pngs from tests to contrib/libtests/crashers
Moved testing of bad pngs into a separate tests/pngtest-badpngs script
Added the --xfail (expected FAIL) option to pngtest.c. It writes XFAIL
in the output but PASS for the libpng test.
Require cmake-3.0.2 in CMakeLists.txt (Clifford Yapp).
Fix "const" declaration info_ptr argument to png_get_eXIf_1() and the
num_exif argument to png_get_eXIf_1() (Github Issue 171).
Version 1.6.32beta11 [August 7, 2017]
Added "eXIf" to "chunks_to_ignore[]" in png_set_keep_unknown_chunks().
Added huge_IDAT.png and empty_ancillary_chunks.png to testpngs/crashers.
Make pngtest --strict, --relax, --xfail options imply -m (multiple).
Removed unused chunk_name parameter from png_check_chunk_length().
Relocated setting free_me for eXIf data, to stop an OSS-fuzz leak.
Initialize profile_header[] in png_handle_iCCP() to fix OSS-fuzz issue.
Initialize png_ptr->row_buf[0] to 255 in png_read_row() to fix OSS-fuzz UMR.
Attempt to fix a UMR in png_set_text_2() to fix OSS-fuzz issue.
Increase minimum zlib stream from 9 to 14 in png_handle_iCCP(), to account
for the minimum 'deflate' stream, and relocate the test to a point
after the keyword has been read.
Check that the eXIf chunk has at least 2 bytes and begins with "II" or "MM".
Version 1.6.32rc01 [August 18, 2017]
Added a set of "huge_xxxx_chunk.png" files to contrib/testpngs/crashers,
one for each known chunk type, with length = 2GB-1.
Check for 0 return from png_get_rowbytes() and added some (size_t) typecasts
in contrib/pngminus/*.c to stop some Coverity issues (162705, 162706,
and 162707).
Renamed chunks in contrib/testpngs/crashers to avoid having files whose
names differ only in case; this causes problems with some platforms
(github issue #172).
Version 1.6.32rc02 [August 22, 2017]
Added contrib/oss-fuzz directory which contains files used by the oss-fuzz
project (https://github.com/google/oss-fuzz/tree/master/projects/libpng).

parenthesis in contrib/pngminus/pnm2png.c (bug report by Christian Hesse).
Fixed off-by-one error in png_do_check_palette_indexes() (Bug report
by Mick P., Source Forge Issue #269).
Version 1.6.33beta02 [September 3, 2017]
Initialize png_handler.row_ptr in contrib/oss-fuzz/libpng_read_fuzzer.cc
to fix shortlived oss-fuzz issue 3234.
Compute a larger limit on IDAT because some applications write a deflate
buffer for each row (Bug report by Andrew Church).
Use current date (DATE) instead of release-date (RDATE) in last
changed date of contrib/oss-fuzz files.
Enabled ARM support in CMakeLists.txt (Bernd Kuhls).
Version 1.6.33beta03 [September 14, 2017]
Fixed incorrect typecast of some arguments to png_malloc() and
png_calloc() that were png_uint_32 instead of png_alloc_size_t
(Bug report by "irwir" in Github libpng issue #175).

issue 162, by rcdailey).
Version 1.6.33rc01 [September 20, 2017]
Initialize memory allocated by png_inflate to zero, using memset, to
stop an oss-fuzz "use of uninitialized value" detection in png_set_text_2()
due to truncated iTXt or zTXt chunk.
Initialize memory allocated by png_read_buffer to zero, using memset, to
stop an oss-fuzz "use of uninitialized value" detection in
png_icc_check_tag_table() due to truncated iCCP chunk.

Version 1.6.33rc02 [September 23, 2017]
Added an interlaced version of each file in contrib/pngsuite.
Relocate new memset() call in pngrutil.c.
Removed more redundant tests (suggested by "irwir" in Github issue #180).
Add support for loading images with associated alpha in the Simplified
API (Samuel Williams).

Revert contrib/oss-fuzz/libpng_read_fuzzer.cc to libpng-1.6.32 state.
Initialize png_handler.row_ptr in contrib/oss-fuzz/libpng_read_fuzzer.cc
Add end_info structure and png_read_end() to the libpng fuzzer.
Version 1.6.34 [September 29, 2017]
Removed contrib/pngsuite/i*.png; some of them caused test failures.
Version 1.6.35beta01 [March 6, 2018]
Restored 21 of the contrib/pngsuite/i*.png, which do not cause test
failures. Placed the remainder in contrib/pngsuite/interlaced/i*.png.

to be NULL, bug report by Lenard Szolnoki).
Version 1.6.35 [July 15, 2018]
Replaced the remaining uses of png_size_t with size_t (Cosmin)

* This is your unofficial assurance that libpng from version 0.71 and

/* zlib.h declares a magic type 'uInt' that limits the amount of data that zlib
* can handle at once. This type need be no larger than 16 bits (so maximum of
* 65535), this define allows us to discover how big it is, but limited by the
* maximuum for png_size_t. The value can be overriden in a library build
* maximum for size_t. The value can be overridden in a library build
* (pngusr.h, or set it in CPPFLAGS) and it works to set it to a considerably
* lower value (e.g. 255 works). A lower value may help memory usage (slightly)
* and may even improve performance on some systems (and degrade it on others.)
