Changes in 4.42:

Backward compatible with 4.41.

All obsolete functions still supported. Current applications will continue to work unchanged.

Faster.

Generates 'normal' fingerprints approximately 4-times faster than 4.41.

Bigger.

Fingerprint objects sizes are still powers-of-two. The idea of folding a fingerprint still applies.

Fingerprint objects can be created in sizes up to 1Gbit (2^30).

A practical limitation on our fingerprint algorithm it that it will only fill a fingerprint to the first 4Mbits (2^22). Larger fingerprints are created properly, and fold correctly down to smaller sizes.

New functions.

Now have the ability get or set individual bits (by bit-number), and to get or set ranges of bits.

Have the ability to control the path-length on fingerprint generation.
