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]
