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]
Initialized btoa[] in pngstest.c
Stop memory leak when returning from png_handle_eXIf() with an error
(Bug report from the OSS-fuzz project).
Version 1.6.32beta04 [August 2, 2017]
Replaced local eXIf_buf with info_ptr-eXIf_buf in png_handle_eXIf().
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 compatability.
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.
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).
Version 1.6.32 [August 24, 2017]
No changes.
There is no documentation in the "cdlabelgen" script that can be
extracted using perldoc(1). Remove the rule invoking perldoc(1)
and remove the need for perldoc(1) as a build tool, which fixes the
build error due to missing
documentation.
Greatly simplify the patch to the project Makefile by moving some
of the logic in the package Makefile. Almost no changes to the
package Makefile are needed if the appropriate variables are
overridden on the make(1) command line.
NEW set term {pngcairo|pdfcairo} pointscale <factor>
NEW "save fit" back-ported from version 5.2 as a replacement for "update"
CHANGE deprecate "update" command (but do not remove it)
CHANGE allow placement of circles in 3D plots using axis coordinates
CHANGE ignore invalid z coordinate for 3D objects placed in "set view map"
CHANGE distinguish 'bind "shift-Button1"' from 'bind "Button1"'
CHANGE use Mingw-w64 and MSVC popen rather than built-in "fake" popen
FIX rangelimited y2 axis could produce spurious diagonal line across plot
FIX assignment of x/y dimensions in "binary record=(a,b) ... with image"
FIX negative array index caused by hidden3d degenerate polygon
FIX object clipping in "set view map"
FIX cairo terminals: scale textbox border linewidth by terminal linewidth
FIX canvas terminal: initialization of plot dimensions (affects first zoom)
FIX crash in stats if no usable data is found
FIX do not use LaTeX formatting in tabular output
FIX additional sanity checks for input data format
FIX more consistent handling of plot 'with table'
FIX incorrect, possibly empty, command string was saved for previous fit
FIX 2D images with logscale axes could fail (segfault)
FIX nested iteration containing an empty range
This package uses CMake to configure the software. Include the
GNUInstallDirs CMake module to define CMAKE_INSTALL_<dir> macros,
and use CMAKE_INSTALL_MANDIR as the location for the installed
manpages. The correct environment variables are passed so that
${CMAKE_INSTALL_MANDIR} points into ${PKGMANDIR}.

Sat, 12 Aug 2017 05:05:24 +0200 Daniel Friesel <derf+feh@finalrewind.org>
* Release v2.19.2
* Show ImageMagick loader errors unless --quiet is specified
* Fix crash when handling certain media keys (introduced in 2.19.1)
This new release includes a significant number of improvements and bug fixes. In particular:
* Multi-threading support at decoding side
* Several speed optimisations both at encoder and decoder, and both on Wavelet Transform and Entropy Coding parts. On our test set, a single-threaded execution is now around 20% faster (encoding or decoding).
* Huge memory consumption reduction at decoding side (~60% reduction on large images)
* Several important bug fixes, in particular the one that was preventing OpenJPEG to encode lossless in some specific situations, as well as those related to mode switches (BYPASS/LAZY, RESTART/TERMALL, etc).
* Several security fixes thanks to the inclusion of OpenJPEG in the Google OSS Fuzz project.
Beside that, several improvements have been brought to the project maintenance, like inclusion of benchmarking scripts to compare speed with latest available kakadu binaries.
And, last but not least, API and ABI are 100% compatible with previous version.

Libfpx is The Flashpix OpenSource Toolkit a library for reading and
writing FlashPix images.
This product includes software developed by the contributors and Digital
Imaging Group, Inc. (http://www.digitalimaging.org/) for use in the
Flashpix Toolkit Project.
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.
