Version
  3.0 (2003.03.12)

=============================================================================

Differences from version 2.1:

- Suboptimal diffusion matrix replaced by cir(1, 1, 4, 1, 8, 5, 2, 9).

=============================================================================

Differences from version 2.0:

- Generation of ISO/IEC 10118-3 test vectors.
- Bug fix: nonzero carry was ignored when tallying the data length (this bug apparently only manifested itself when feeding data in pieces rather than in a single chunk at once).
- Support for MS Visual C++ 64-bit integer arithmetic.

Differences from version 1.0:

- Original S-box replaced by the tweaked, hardware-efficient version.
