0.3.0:
- alf's compression speed is now acceptably fast.

0.2.1 (never released):

- alf is now able to create .alf archives that are byte-for-byte
  identical with ones created by LZ.COM on the Atari.
- alf: compression is faster (but still too slow).
- alf: can now handle empty (0-byte length) files, which LZ.COM can't.
- alf: add some -t<x> options to control timestamps.
- unalf: actually use the timestamps in the .alf file.
- unalf: show 4-digit year with -v option.
- various bugfixes.
- add this CHANGES.txt file :)

0.2.0:

- alf command added.
- Project renamed to alftools, since unalf isn't a good description.

0.1.0 was released as "unalf".
