This version adds grayscale native support (PGM format), plus four binarization methods. It also adds an internal preprocessor including deskewing, balancing, thresholding, and interpolation, and has been packaged for NetBSD. There are various new features including border path computing, barcode search, detection of extremities, PAGE only mode, the flea, the spyhole, instant threshold, per-depth optimized X code, many bugfixes, and other interface enhancements. The documentation was updated (but not finished), and a glossary was added.
