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.

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.

1.6.40
Fixed the eXIf chunk multiplicity checks.
Fixed a memory leak in pCAL processing.
Corrected the validity report about tRNS inside png_get_valid().
Fixed various build issues on *BSD, Mac and Windows.
Updated the configurations and the scripts for continuous integration.
Cleaned up the code, the build scripts, and the documentation.

Historically, the MD5 checksums in our LFS files serve as a protection
against broken downloads, or accidentally corrupted source files.
While the sources are nowadays downloaded via HTTPS, it make sense to
beef up integrity protection for them, since transparently intercepting
TLS is believed to be feasible for more powerful actors, and the state
of the public PKI ecosystem is clearly not helping.
Therefore, this patch switches from MD5 to BLAKE2, updating all LFS
files as well as make.sh to deal with this checksum algorithm. BLAKE2 is
notably faster (and more secure) than SHA2, so the performance penalty
introduced by this patch is negligible, if noticeable at all.
In preparation of this patch, the toolchain files currently used have
been supplied with BLAKE2 checksums as well on
https://source.ipfire.org/.

Most of these files still used old dates and/or domain names for contact

Just some housekeeping... :-)

These all fix a potential "NULL dereference" bug that has existed in libpng
since version 0.71 of June 26, 1995. To be vulnerable, an application
has to load a text chunk into the png structure, then delete all text, then
add another text chunk to the same png structure, which seems to be
an unlikely sequence, but it has happened.
