Release Notes: This release adds ARMv8 support and improves unknown chunk support.
Release Notes: This release removes two stray lines of code in arm/arm_init.c which were accidentally inserted in libpng-1.6.4 and caused compilation to fail on the ARM platform.
Release Notes: This release adds minor improvements in speed and footprint.
Release Notes: This release provides a minor update to the ARM support. There are new "pngfix" and "png-fix-itxt" programs in the contrib/tools directory. "pngfix" optimizes the CMF bytes of the zlib datastream in the IDAT chunks, and "png-fix-itxt" fixes PNG files that were created with libpng-1.6.0 or 1.6.1 that have an incorrect length field in the iTXt chunks.
Release Notes: This is a cleanup release with no new features or significant bugfixes. The default gamma handling is improved in the new simplified API.
