@ -6129,6 +6129,73 @@ Version 1.6.40 [June 21, 2023]
Updated the configurations and the scripts for continuous integration.
Cleaned up the code, the build scripts, and the documentation.
Version 1.6.41 [January 24, 2024]
Added SIMD-optimized code for the LoongArch LSX hardware.
(Contributed by GuXiWei, JinBo and ZhangLixia)
Fixed the run-time discovery of MIPS MSA hardware.
(Contributed by Sui Jingfeng)
Fixed an off-by-one error in the function png_do_check_palette_indexes(),
which failed to recognize errors that might have existed in the first
column of a broken palette-encoded image. This was a benign regression
accidentally introduced in libpng-1.6.33. No pixel was harmed.
(Contributed by Adam Richter; reviewed by John Bowler)
Fixed, improved and modernized the contrib/pngminus programs, i.e.,
png2pnm.c and pnm2png.c
Removed old and peculiar portability hacks that were meant to silence
warnings issued by gcc version 7.1 alone.
(Contributed by John Bowler)
Fixed and modernized the CMake file, and raised the minimum required
CMake version from 3.1 to 3.6.
(Contributed by Clinton Ingram, Timothy Lyanguzov, Tyler Kropp, et al.)
Allowed the configure script to disable the building of auxiliary tools
and tests, thus catching up with the CMake file.
(Contributed by Carlo Bramini)
Fixed a build issue on Mac.
(Contributed by Zixu Wang)
Moved the Autoconf macro files to scripts/autoconf.
Moved the CMake files (except for the main CMakeLists.txt) to
scripts/cmake and moved the list of their contributing authors to
scripts/cmake/AUTHORS.md
Updated the CI configurations and scripts.
Relicensed the CI scripts to the MIT License.
Improved the test coverage.
(Contributed by John Bowler)
Version 1.6.42 [January 29, 2024]
Fixed the implementation of the macro function png_check_sig().
This was an API regression, introduced in libpng-1.6.41.
(Reported by Matthieu Darbois)
Fixed and updated the libpng manual.
Version 1.6.43 [February 23, 2024]
Fixed the row width check in png_check_IHDR().
This corrected a bug that was specific to the 16-bit platforms,
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.
