The license has been changed to a two-clause BSD
license with the option
to switch to GPL version 2 or any later version.
The compression speed
has been increased considerably, and the user can
now chose between
roughly the same speed as fastlz with a better
compression ratio, or a
faster speed than fastlz at a slightly worse
compression ratio. The lzf
utility has been improved to act much more like
other similar utilities
(e.g. gzip).
