|
||||
Changes from version 1.6.42 to version 1.6.43
|
||||
---------------------------------------------
|
||||
|
||||
* 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)
|

|
||||
|
||||
Changes from version 1.6.40 to version 1.6.41
|
||||
---------------------------------------------
|
||||
|
||||
* 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.
|
||||
* 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 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.
|
||||
* 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.
