 ---------------------------------------------
 
- * Hardened calculations in chroma handling to prevent overflows, and
-   relaxed a constraint in cHRM validation to accomodate the standard
-   ACES AP1 set of color primaries.
+ * Added support for the cICP chunk.
+   (Contributed by Lucas Chollet and John Bowler)
+ * Adjusted and improved various checks in colorspace calculations.
    (Contributed by John Bowler)
- * Removed the ASM implementation of ARM Neon optimizations and updated
-   the build accordingly. Only the remaining C implementation shall be
-   used from now on, thus ensuring the support of the PAC/BTI security
-   features on ARM64.
-   (Contributed by Ross Burton and John Bowler)
- * Fixed the pickup of the PNG_HARDWARE_OPTIMIZATIONS option in the
-   CMake build on FreeBSD/amd64. This is an important performance fix
-   on this platform.
- * Applied various fixes and improvements to the CMake build.
-   (Contributed by Eric Riff, Benjamin Buch and Erik Scholz)
- * Added fuzzing targets for the simplified read API.
-   (Contributed by Mikhail Khachayants)
- * Fixed a build error involving pngtest.c under a custom config.
-   This was a regression introduced in a code cleanup in libpng-1.6.43.
-   (Contributed by Ben Wagner)
- * Fixed and improved the config files for AppVeyor CI and Travis CI.
+ * Rearranged the write order of colorspace chunks for better conformance
+   with the PNG v3 draft specification.
+   (Contributed by John Bowler)
+ * Raised the minimum required CMake version from 3.6 to 3.14.
+ * Forked off a development branch for libpng version 1.8.
