I have released version 2.67 of razor-agents on sourceforge. The
version released yesterday (2.66), has a bug that manifests in
terms of disabling the Whiplash engine. If you are running 2.66,
please upgrade immediately.

Here's a link to the tarball:

Change log:

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 signatures 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 improvement 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 malformed.

cheers,
vipul
