0.20.1 (November 4, 2003)

 INTRODUCTION
 
 v0.20.1 is a minor update on v0.20.0 to address the performance problems that some 
 people were seeing with the introduction of the BerkeleyDB for storage of the corpus.  
 v0.20.1 sets the BerkeleyDB cache size (i.e. the amount of the corpus that is kept 
 in memory) to 64KB and it can be controlled through the bayes_db_cache_size 
 parameter if needed.  The default should work for everyone, you can set this to a 
 higher value to keep more of the database in memory at the cost of using more 
 memory.
 
 There are also a number of bug fixes in v0.20.1:
 
 1. If you set a password and used X-POPFile-Link you were unable to get past
    the password screen when clicking on an XPL. (bug #831472)
 
 2. In some instances when the connection between the POP3 proxy and the mail
    server was lost it was possible to get in a deadlock where POPFile was 
    waiting for a command from the client and the client was waiting for a 
    response from POPFile. (bug #829947)
 
 3. It was not possible to add pseudowords (e.g. header:From) as ignored words,
    now it is. (bug #827785)
 
 4. Magnets that included $ or @ could be incorrectly matched when the @ or $ 
    was followed by __. (bug #826765)
 
 
 ESSENTIAL READING IF YOU ARE UPGRADING TO v0.20.1
 
 1. BACK UP YOUR OLD INSTALLATION: POPFile makes this really easy, just copy
    the entire POPFile directory somewhere.  You can then safely install
    POPFile v0.20.1 on top of your current installation; I just think a back up
    is a sensible precaution.
 
 2. IF YOU ARE RUNNING WINDOWS: Please read the section below I AM RUNNING
    WINDOWS AND NEED TO CHECK MULTIPLE EMAIL ACCOUNTS SIMULTANEOUSLY
 
 3. ON WINDOWS POPFILE IS NOW AN EXE.  Windows users will now be able to see
    POPFile running in the Task Manager with an executable called popfileXX.exe
    where the XX is one of f, if, b, ib depending on configuration.  POPFile
    is started by running popfile.exe which chooses the appropriate popfileXX.exe
 
    This might cause your firewall to ask about giving popfileXX.exe permissions, 
    in addition if you had allowed Perl permissions in your firewall they are
    NO LONGER needed.
 
 4. The installer will cause POPFile to run in the foreground if the database
    upgrade is required so that the upgrade process is evident to the user. 
    Once upgraded you can switch to background my going to the Configuration
    tab and changing "Run POPFile in a console window?" to No.
 
 
 I AM RUNNING WINDOWS AND NEED TO CHECK MULTIPLE EMAIL ACCOUNTS SIMULTANEOUSLY
 
 Because the time taken to start a new process on Windows is long under Perl
 there is an optimization for Windows that is present by default: when a new
 connection is made between your email program and POPFile, POPFile handles it
 in the 'parent' process.  This means that the connect happens fast and mail
 starts downloading very quickly, but is means that you can only downloaded
 messages from one server at a time (up to 6 other connections will be queued
 up and dealt with in the order they arrive) and the UI is unavaiable while
 downloading email.
 
 You can turn this behavior off (and get simultaneous UI/email access and as
 many email connections as you like) by going to the Configuration panel in
 the UI and making sure that "Allow concurrent POP3 connections:" is set to
 Yes, or by specifying -pop3_force_fork 1 on the command line.
 
 
 I AM USING THE CROSS PLATFORM VERSION
 
 POPFile requires a number of Perl modules that are available from CPAN.  New
 in v0.20.x are the need for the following:
 
  BerkeleyDB
  Text::Kakasi (if you want Japanese language support)
  Encode       (if you want Japanese language support)
 
 
 I LIKE TO LIVE DANGEROUSLY
 
 In a future version POPFile will add official support for message classification
 through the SMTP and NNTP (Usenet news) protocols.  There are currently proxy
 modules for these protocols that work with v0.20.1, but they have not been 
 fully tested.  If you are interested in getting them get them here:
 
 http://cvs.sourceforge.net/viewcvs.py/*checkout*/popfile/engine/Proxy/SMTP.pm?rev=1.22
 http://cvs.sourceforge.net/viewcvs.py/*checkout*/popfile/engine/Proxy/NNTP.pm?rev=1.21
 
 and place them in POPFile's Proxy/ directory.  
 
 
 DOWNLOADING

 UPGRADING
 
 Just install POPFile on top of the currently installed version.  But did you
 read the ESSENTIAL READING above first.
 
 
 INTERNATIONALIZATION
 
 This minor update includes localization into Turkish.
