Changes since the last public release (1.6.26):
Version 1.6.27beta01 [October 28, 2016]
Version 1.6.27beta01 [November 2, 2016]
Restrict the new ADLER32-skipping to IDAT chunks. It broke iCCP chunk
handling.
handling: an erroneous iCCP chunk would throw a png_error and reject the
entire PNG image instead of rejecting just the iCCP chunk with a warning,
if build with zlib-1.2.8.1.
