Changes since the last public release (1.6.1):
Version 1.6.2beta01 [April 14, 2013]
Updated documentation of 1.5.x to 1.6.x changes in iCCP chunk handling.
Fixed incorrect warning of excess deflate data. End condition - the
warning would be produced if the end of the deflate stream wasn't read
in the last row. The warning is harmless.
Corrected the test on user transform changes on read. It was in the
png_set of the transform function, but that doesn't matter unless the
transform function changes the rowbuf size, and that is only valid if
transform_info is called.
Corrected a misplaced closing bracket in contrib/libtests/pngvalid.c
(Flavio Medeiros).
Corrected length written to uncompressed iTXt chunks (Samuli Suominen).
Version 1.6.2rc01 [April 18, 2013]
Added contrib/tools/fixitxt.c, to repair the erroneous iTXt chunk length
written by libpng-1.6.0 and 1.6.1.
