The Change Log is:

* New Features and Improvements *
- The "clamavmodule" scanner cannot unpack archives of RAR version 3.
  2 new configuration settings allow you to unpack the latest RAR archives
  for testing by the "clamavmodule" scanner.
  It also enables the contents of the RAR archive to be checked for illegal
  filenames and filetypes, and also to see if they are password-protected.
  Unrar Command = /usr/bin/unrar
  Unrar Timeout = 50
- "Allow Password-protected Archives" can now be a ruleset when using the
  clamavmodule virus scanner.
- Multiple "Subject:" lines are removed. The 1st one is kept.
- If the "Unrar Command" is defined and points to an executable program,
  it will automatically be used by the "clamav" scanner. No -wrapper
  tweaking is needed to do this any more.
- You can now use shell environment variables such as $HOSTNAME or
  ${HOSTNAME} in MailScanner.conf and its relatives.
- More improvements to the phishing net.
- More additions to the starter phishing.safe.sites.conf file.
- Removed my spam.assassin.prefs.conf file in favour of the one from
  www.fsl.com, with just enough changes to produce an identical file
  layout to my previous versions.
- Re-enabled ALL_TRUSTED rule after comments from Matt Kettler. Thanks!
- Added long comment about ALL_TRUSTED rule, many thanks to Matt Kettler.
- Improved screen behaviour of RPM-based init.d script.
- Greatly improved RAR archive handler, thanks to Rick Cooper.
- Changed IPBlock DSN to 550 and made it easily configurable.
  Look for "$FailCode" in the CustomConfig.pm code and the IPBlock cron job.
- Changed the "Envelope-From" and "Envelope-To" headers to include your
  organisation's name.
- Made date and time stamps consistent across whole system.
- Added extra rules to the phishing net to avoid false alarms with some
  examples of Microsoft's .NET system.
- Added Custom Functions to implement multiple input and output queues for
  ZMailer users. Many thanks to MailScanner-devel at pert.com.ar (Leonardo
  Helman and Mariano Absatz) for all their hard work implementing this.
- Improved RedHat init.d script so reload is handled better for Postfix.
- Changed default supplied values for "Allow xxxxx Tags" to disarm all of
  these tags.
- Added 20 minute timeout to bitdefender's autoupdate script. Easy to set
  the timeout to your own value, just look at the start of the script.
- Added support for non-hashed queue directories for Postfix 2.2.

* Fixes *
- Fixed problem with missing Attachment-Warning when encountering a virus
  that is both silent and non-forging.
- Improved output format of Sender warning, and removed duplicate lines.
- In IPBlock facility, changed MTA dsn to 451 to temporarily refuse the
  connections, rather than the total block it used to do.
- Removed erroneous log output from SpamAssassin bayes-rebuilder.
- Postfix problem fixes.
- Fixed SpamAssassin Bayes database rebuild timeout problem.
- Fixed Exim problem with removing multiple "Subject:" headers.
- Fixed Postfix problem with removing multiple "Subject:" headers.
- Fixed problems in new Unrar code when renaming files in archives.
- Fixed problems in earlier betas with occasional missing attachment
warnings.
- Fixed directory problem in vexira-autoupdate.
- Fixed problems with defunct processes when not virus scanning.
- Fixed problem with filename checks not happening without virus scanning.
- Fixed problem extracting RAR archives with filenames containing special
  characters.
- Fixed problem where 2 matching "No" rules would cause message to be
checked
  for spam, if SpamChecks is moved in ConfigDefs.pl.
