* 2005/12/12 23:19:49 Fixed bugs with FCS handling that could lead to
  unnecessary packet cropping (although this bug may have been

  unscrambling validation.  Fixed a bug in ipv6 scrambling (could
  break "common-prefix preservation property of the anonymization).

=== Release 0.2 ===

  caused by (undocumented?) Ether FCS bits sometimes found at the end

  "common-prefix preservation" property of the anonymization), added
  reverse lookup capability for holders of the secret key (ip4 only),
  updated dag_scrubber's repair mode to look beyond several KB for
  intelligible records.

* 2005/09/22 17:54:29 Added -M option for dag_scrubber (enforce
  monotonously increasing TS)
