Changes since the previous public release (1.6.34):
Restored 21 of the contrib/pngsuite/i*.png, which do not cause test
failures. Placed the remainder in contrib/pngsuite/interlaced/i*.png.
Added calls to png_set_*() transforms commonly used by browsers to
the fuzzer.
Removed some unnecessary brackets in pngrtran.c
Fixed miscellaneous typos (Patch by github user "luzpaz").
Change "ASM C" to "C ASM" in CMakeLists.txt
Fixed incorrect handling of bKGD chunk in sub-8-bit files (Cosmin)
Added hardware optimization directories to zip and 7z distributions.
Fixed incorrect bitmask for options.
Fixed many spelling typos.
Make png_get_iCCP consistent with man page (allow compression-type argument
to be NULL, bug report by Lenard Szolnoki).
Replaced the remaining uses of png_size_t with size_t (Cosmin)
Fixed the calculation of row_factor in png_check_chunk_length
(reported by Thuan Pham in SourceForge issue #278)
Added missing parentheses to a macro definition
(suggested by "irwir" in GitHub issue #216)
IMPORTANT licensing update: libpng license v2
---------------------------------------------

The new libpng license comprises the terms and conditions from the zlib
license, and the disclaimer from the Boost license.
The legacy libpng license, used until libpng-1.6.35, is appended to the
new license, following the precedent established in the Python Software
Foundation License version 2.
From now on, the list of contributing authors shall be maintained in a
separate AUTHORS file. The lists of previous contributing authors,
mentioned in the legacy libpng license and considered to be an integral
part of that license, are kept intact, with no further updates.
