Fixed a typo in pngrutil.c, introduced in libpng-1.5.6, that interferes
with "blocky" expansion of sub-8-bit interlaced PNG files (Eric Huss).
Version 1.6.11beta04 [April 13, 2014]
Version 1.6.11beta04 [April 19, 2014]
Made progressive reading of interlaced images consistent with the
behavior of the sequential reader and consistent with the manual. The
row_callback now receives the proper pass number and unexpanded rows,
when png_combine_row is not used or not built, by moving some code
out of the PNG_READ_INTERLACING_SUPPORTED blocks.
