Bogofilter 0.92.0 released

Bogofilter is a mail filter that classifies email as spam or ham
(non-spam) by a statistical analysis of the message's header and content
(body).  The program is able to learn from the user's classifications
and corrections.

The statistical technique is known as the Bayesian technique and its use
for spam was described by Paul Graham in his article "A Plan For Spam". 
Gary Robinson, in his weblog Rants, suggests some refinements for
improved discrimination between spam and ham.  Bogofilter's primary
algorithm uses the f(w) parameter and the Fisher inverse chi-square
technique that he describes.

Bogofilter is run by an MDA script to classify an incoming message as
spam or ham (using wordlists stored by BerkeleyDB).  Bogofilter provides
processing for plain text and html, supports multi-part mime message
with decoding of base64, quoted-printable, and uuencoded text and
ignores attachments, such as images.

Bogofilter is written in C.  Supported platforms: Linux, FreeBSD,
Solaris, OS X, HP-UX, AIX, RISC-OS, OS/2, ...

  files with CRLFs and X-Bogosity line as last header line.

* Added ESF options to bogofilter's and man page.
* Revised man pages' description of multi-parameter options.

* t.lock3 regression modified for solaris shell compatibility.

0.91.4	2004-06-20

* Fix abort during db_open (ds_open wasn't first calling
  ds_init).
* Added regression test t.lock3 for this fix.
* Revise datastore and database levels so that each level
  calls its own init() and cleanup() routines.

0.91.3	2004-06-15
	
* Added format specification '%I' to allow logging of the IP
  address from which an email was received.

* Avoid "Invalid buffer size, exiting." problems by discarding
  text from an excessively long html tag.

0.91.2	2004-06-11

* FAQ updated with info on multiple wordlists and ignore
  lists.
* FAQ updated with info on building as non-root user.

* Bogofilter's creation of new wordlists now includes
  .WORDLIST_VERSION token.
* Fix erroneous double opening of wordlists specified on
  command line.
* Corrected tests so that "make check" passes with qdbm and
  tdb.

* Fix included GSL compile for compilers that do not support
  "extern inline", such as Compaq C V6.3.

0.91.1	2004-06-04

* Use named constants for wordlist 'type' attribute to
  distinguish open modes of READ, WRITE, and CREATE so
  bogofilter will include .WORDLIST_VERSION in new database.
* Add DS_LOAD flag so bogoutil won't add .WORDLIST_VERSION
* Modify regression tests to use bogoutil to create empty
  wordlists (as needed).

* Fixed registration.  When multiple wordlists are specified,
  registration is to first regular wordlist.
* Added regresstion test for multiple wordlists.

* Lower output precision for regression tests, by using %f
  rather than %e, to mask differences between GSL versions.
* Updated TODO list and procmailrc.example

* Added code for Robinson's Effective Size Factor (ESF) 
  to score.c, bogotune.c, bogofilter.cf.example, etc.
* Added '-E' options to bogotune to suppress ESF scan.
* Revised bogotune's parameter ranges.

* Remove unreferenced enum wl_e.
* Add .WORDLIST_VERSION meta symbol.
* Change subnet prefix from url: to ip:
* Add -u switch to bogoutil to do wordlist upgrade.

* Added code for Robinson's Effective Size Factor (ESF) 
  to score.c, bogotune.c, bogofilter.cf.example, etc.
* Added '-E' options to bogotune to suppress ESF scan.
* Revised parameter ranges for coarse scan.

* Changed list address in FAQ to bogofilter.org
