Changes since 2.40:
===================
       2.67 (December 03, 2004)

       +   This is a patch release that fixes a bug in the
           Whiplash signature scheme. The bug was in the new code
           added to support canonicalization of domains. It
           caused the signature algorithm to generate no signa-
           tures on valid content.

       2.66 (December 02, 2004)

       +   Introduced support for country domain canonicalization
           in the Whiplash signature scheme. This means domains
           like foo.co.uk would be extracted correctly by
           Whiplash. This change affords a considerable improve-
           ment in accuracy.

       +   Modified the revocation logic to do signature-only
           communications with the server. All versions of
           razor-agents prior to this sent the entire message on
           razor-revoke, and even though the backend would drop
           the messages after computing signatures, this entailed
           a privacy risk. From this version on razor-agents will
           _never_ send the contents of a revoked message to the
           backend servers.

       +   Fixed a bug in "se" (supported engines) computation,
           which was broken when the "se" mask was larger than 8
           bits. This would sometimes disable the use of engine 4
           (ehash). This fix would also afford an increase in
           accuracy due to ehash being used everytime.

       +   Fixed a bug in report by message. Version 2.61 would
           drop MIME headers on certain spam messages which would
           cause the backend to ignore these messages as mal-
           formed.

2.61 (July 06, 2004)
       +   Introduced the Whiplash signature scheme. Whiplash
           signatures are based on canonical domain names present
           in URLs embedded in spam messages. A Whiplash signa-
           ture is also a function of the length of the spam mes-
           sage. It's important to note that not all whiplashes
           are used as classifiers. The Whiplash engine is aug-
           mented by sophesticated logic on the Razor2 backend to
           select the Whiplashes that are used to filter spam.

       +   Fixed a bug in MIME parser whereby some broken MIME
           mails were invisible to the system. [Bug #788723]

       +   We override the "use_engines" parameter in the config
           file because this version supports different engines
           but leaves the config file untouched. [Bug #984374]

       +   Engine 1 support completely removed. Engine 1 was a
           signature scheme compatible with the old razor v1 sig-
           natures, which is no longer supported on the backend.
           [Bug #975490]
