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.
(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.
