Changes from version 1.6.46 to version 1.6.47
Changes from version 1.6.47 to version 1.6.48
---------------------------------------------
* 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 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)
* Fixed the floating-point version of the mDCv setter `png_set_mDCv`.
(Reported by Mohit Bakshi; fixed by John Bowler)
* Added #error directives to discourage the inclusion of private
libpng implementation header files in PNG-supporting applications.
* Added the CMake build option `PNG_LIBCONF_HEADER`, to be used as an
alternative to `DFA_XTRA`.
* Removed the Travis CI configuration files, with heartfelt thanks for
their generous support of our project over the past five years!
