- * 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.
+ * 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.

+ * Fixed a build issue on Mac.
+ (Contributed by Zixu Wang)
+ * Moved the Autoconf macro files to scripts/autoconf.
