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.

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.

Fixed a preprocessor condition in pngread.c that broke build-time configurations like contrib/conftest/pngcp.dfa.

Added CMake build support for LoongArch LSX.

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.

Marked the installed libpng headers as system headers in CMake.

Updated the build support for RISCOS.

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.

Replying to Xi Ruoyao:

Oops, apng patch does not apply.

It seems trivial and can be manually corrected.

[Bruce Dubbs]

There is a new patch now that applies correctly.
