libpng-2.0
* Fri Aug 01 2025 Petr Vorel <pvorel@suse.cz>
- version update to 1.6.50:
* Improved the detection of the RVV Extension on the RISC-V platform.
(Contributed by Filip Wasil)
* Replaced inline ASM with C intrinsics in the RVV code.
(Contributed by Filip Wasil)
* Fixed a decoder defect in which unknown chunks trailing IDAT, set
to go through the unknown chunk handler, incorrectly triggered
out-of-place IEND errors.
(Contributed by John Bowler)
* Fixed the CMake file for cross-platform builds that require `libm`.
- version update to 1.6.49:
* Added SIMD-optimized code for the RISC-V Vector Extension (RVV).
(Contributed by Manfred Schlaegl, Dragos Tiselice and Filip Wasil)
* Added various fixes and improvements to the build scripts and to
the sample code.
- version update to 1.6.48:
* Fixed the floating-point version of the mDCv setter `png_set_mDCv`.
(Reported by Mohit Bakshi; fixed by John Bowler)
* Added #error directives to discourage the inclusion of private
libpng implementation header files in PNG-supporting applications.
* Added the CMake build option `PNG_LIBCONF_HEADER`, to be used as an
alternative to `DFA_XTRA`.
* Removed the Travis CI configuration files, with heartfelt thanks for
their generous support of our project over the past five years!
- version update to 1.6.47:
* Modified the behaviour of colorspace chunks in order to adhere
to the new precedence rules formulated in the latest draft of
the PNG Specification.
(Contributed by John Bowler)
* Fixed a latent bug in `png_write_iCCP`.
This would have been a read-beyond-end-of-malloc vulnerability,
introduced early in the libpng-1.6.0 development, yet (fortunately!)
it was inaccessible before the above-mentioned modification of the
colorspace precedence rules, due to pre-existing colorspace checks.
(Reported by Bob Friesenhahn; fixed by John Bowler)
- version update to 1.6.46:
* Added support for the mDCV and cLLI chunks.
(Contributed by John Bowler)
* Fixed a build issue affecting C89 compilers.
This was a regression introduced in libpng-1.6.45.
(Contributed by John Bowler)
* Added makefile.c89, specifically for testing C89 compilers.
* Cleaned up contrib/pngminus: corrected an old typo, removed an old
workaround, and updated the CMake file.
- version update to 1.6.45:
* Added support for the cICP chunk.
(Contributed by Lucas Chollet and John Bowler)
* Adjusted and improved various checks in colorspace calculations.
(Contributed by John Bowler)
* Rearranged the write order of colorspace chunks for better conformance
with the PNG v3 draft specification.
(Contributed by John Bowler)
* Raised the minimum required CMake version from 3.6 to 3.14.
* Forked off a development branch for libpng version 1.8.
* Tue Oct 29 2024 Guillaume GARDET <guillaume.gardet@opensuse.org>
- version update to 1.6.44:
* Hardened calculations in chroma handling to prevent overflows, and
relaxed a constraint in cHRM validation to accomodate the standard
ACES AP1 set of color primaries.
(Contributed by John Bowler)
* Removed the ASM implementation of ARM Neon optimizations and updated
the build accordingly. Only the remaining C implementation shall be
used from now on, thus ensuring the support of the PAC/BTI security
features on ARM64.
(Contributed by Ross Burton and John Bowler)
* Fixed the pickup of the PNG_HARDWARE_OPTIMIZATIONS option in the
CMake build on FreeBSD/amd64. This is an important performance fix
on this platform.
* Applied various fixes and improvements to the CMake build.
(Contributed by Eric Riff, Benjamin Buch and Erik Scholz)
* Added fuzzing targets for the simplified read API.
(Contributed by Mikhail Khachayants)
* Fixed a build error involving pngtest.c under a custom config.
This was a regression introduced in a code cleanup in libpng-1.6.43.
(Contributed by Ben Wagner)
* Fixed and improved the config files for AppVeyor CI and Travis CI.

and removed a spurious compiler warning from the 64-bit builds.
(Reported by Jacek Caban; fixed by John Bowler)
* Added eXIf chunk support to the push-mode reader in pngpread.c.
(Contributed by Chris Blume)
* Added contrib/pngexif for the benefit of the users who would like
to inspect the content of eXIf chunks.
* Added contrib/conftest/basic.dfa, a basic build-time configuration.
(Contributed by John Bowler)
* Fixed a preprocessor condition in pngread.c that broke build-time
configurations like contrib/conftest/pngcp.dfa.
(Contributed by John Bowler)
* Added CMake build support for LoongArch LSX.
(Contributed by GuXiWei)
* Fixed a CMake build error that occurred under a peculiar state of the
dependency tree. This was a regression introduced in libpng-1.6.41.
(Contributed by Dan Rosser)
* Marked the installed libpng headers as system headers in CMake.
(Contributed by Benjamin Buch)
* Updated the build support for RISCOS.
(Contributed by Cameron Cawley)
* Updated the makefiles to allow cross-platform builds to initialize
conventional make variables like AR and ARFLAGS.
* Added various improvements to the CI scripts in areas like version
consistency verification and text linting.
* Added version consistency verification to pngtest.c also.
