Changes since the last public release (1.0.46): Changes since the last public release (1.0.47):
version 1.0.47 [July 16, 2009] version 1.0.48 [August 13, 2009]
Revised libpng*.txt and libpng.3 to mention calling png_set_IHDR()
multiple times and to specify the sample order in the tRNS chunk,
because the ISO PNG specification has a typo in the tRNS table.
Changed several PNG_UNKNOWN_CHUNK_SUPPORTED to
PNG_HANDLE_AS_UNKNOWN_SUPPORTED, to make the png_set_keep mechanism
available for ignoring known chunks even when not saving unknown chunks.
Added PNG_NO_HANDLE_AS_UNKNOWN in the PNG_LEGACY_SUPPORTED block of
pngconf.h, and moved the various unknown chunk macro definitions
outside of the PNG_READ|WRITE_ANCILLARY_CHUNK_SUPPORTED blocks.
Added a reference to the libpng license in each source file.
Rebuilt configure scripts with autoconf-2.63.
Added a prototype for png_64bit_product() in png.h
Expanded the information about prototypes in the libpng style section of
the documentation.
Rebuilt configure scripts with autoconf-2.64.
Avoid a possible NULL dereference in debug build, in png_set_text_2().
(bug introduced in libpng-0.95, discovered by Evan Rouault)
Replaced *.tar.lzma with *.tar.xz in distribution. Get the xz codec
from <http://tukaani.org/xz>.
Reject attempt to write iCCP chunk with negative embedded profile length
