Changes from version 1.6.45 to version 1.6.46
Changes from version 1.6.46 to version 1.6.47
---------------------------------------------
* Added support for the mDCV and cLLI chunks.
* Modified the behaviour of colorspace chunks in order to adhere
to the new precedence rules formulated in the latest draft of
the PNG Specification.
(Contributed by John Bowler)
* Fixed a build issue affecting C89 compilers.
This was a regression introduced in libpng-1.6.45.
(Contributed by John Bowler)
* Added makefile.c89, specifically for testing C89 compilers.
* Cleaned up contrib/pngminus: corrected an old typo, removed an old
workaround, and updated the CMake file.
* Fixed a latent bug in `png_write_iCCP`.
This would have been a read-beyond-end-of-malloc vulnerability,
introduced early in the libpng-1.6.0 development, yet (fortunately!)
it was inaccessible before the above-mentioned modification of the
colorspace precedence rules, due to pre-existing colorspace checks.
(Reported by Bob Friesenhahn; fixed by John Bowler)
