Release Notes: A fix for a bug in compression level zero, and a new class which permits input from a BufferedImage, so that you can create PNGs from an 8-bit-per-pixel source. The new class requires Java 1.2; the original still works with Java 1.1.
Release Notes: Addition of "sub" and "up" filters. Documentation moved to a new directory. Test program updated. You can now set compression level for Deflater.
Release Notes: Initial release.
