Version 0.8.0   - UNRELEASED

  * Fixed date header parsing to be precise with timezone information.  Also,
    when writing From_ line timestamps, don't use UTC but local time, without
    timezone information.
  * To determine the delivery date of a message, archivemail now looks for the
    timestamp of the latest 'Received' header before resorting to
    'Resent-Date' or 'Date'.  This should give much better results when there
    is no 'Delivery-date' header, which is still checked first.
    (Thanks Andrew Ferrier & Christian Brabandt)
    Closes: #1481316, #1764855, Debian bug #272666.
  * If present, the 'Resent-date' header now takes precedence over 'Date'.
  * IMAP: recognize when a server advertises LOGINDISABLED.
  * New option --debug-imap; this just sets imaplib.Debug, thereby dumping
    archivemail's chat with the server to stdout.
  * Fixed crash with Python 2.5 when archiving an empty maildir.
    (Thanks "Aidant")  Closes: #1878940.
  * New option --all to archive all messages in a mailbox.  Closes: #1764846.
  * Fixed a crash when archiving maildirs with --days=0. (Thanks John Goerzen)
  * IMAP: automatically add NAMESPACE prefix to a mailbox path if necessary.
  * Removed the feature to setuid to the mailbox owners when run as root.
    This was a bad idea; it's really hard to do safely, if at all possible.
    Obsoletes: patch #2783134.
  * Replaced some simple minded file operation security checks with more
    decent ones.  This means we can safely operate in /tmp, for example.  The
    price is that we no longer accept symlinked files.  Obsoletes: patch
    #1874868.
  * Don't use rename() to update mbox files and the archive, but write the
    files directly.  This is more fragile, but required for correct mbox
    locking, and also for mboxes in mail spool directories where we don't have
    permission to create files.  It also means that if selinux is enabled,
    archivemail now preserves the selinux security context of an mbox.
    Closes: #2210732.
  * Fixed the test suite to deal with nanosecond file timestamps.  These are
    provided by ext4 and XFS, for example.  Closes: #2043900.
  * Cleaned up the test suite, replacing a lot of duplicated code and avoiding
    a lot of redundand testing.  This speeds up the test suite by a factor of
    15 or so.
  * mbox locking got completely rewritten.  Switched from flock to lockf
    locking, which is NFS-safe and portable, and we now lock with lockf first,
    then with a dotlock, instead of the other way around.  (This is makes
    archivemail compatible with Debian systems. ;)
  * We now omit the dotlock if we don't have sufficient permissions to create
    it in the mbox directory. (The file is still locked with lockf.)
    Since we also no longer use rename() to commit changes to an mbox, (see
    above) this means archivemail can now operate on mbox files in the system
    mail spool.  Closes: #855269.
  * Refactoring of the mbox classes; much of the code got rewritten.
  * The archive now also gets locked while archivemail updates it.
  * Various Python language fixes (for example don't use "0" and "1" as
    boolean constants).
  * Added a lot of test cases for maildir archiving to the test suite.
    Maildir testing should now be roughly on par with mbox testing.
  * IMAP servers (Dovecot and UW-IMAP at least) may store mailbox meta data
    for mboxes in a pseudo message.  Such messages are now detected and never
    archived.  Obsoletes: patch #2210707.  (Thanks, "tlhackque")
  * New option --prefix, or short -p, to specify an archive name prefix.  Like
    a suffix specified with the --suffix option, the prefix is expanded with
    strftime().  Specifying this option disables the default archive name
    suffix.  Obsoletes: feature request #604281.  (Thanks Serafeim Zanikolas
    for an initial patch)

Version 0.7.2   - 9 November 2007

  * IMAP: fixed crash by working around python bug #1277098, which is still pending
    in python << 2.5. 

Version 0.7.1   - 7 November 2007

  * Fixed incompatibility with Python 2.5 which broke Maildir handling.
    Closes: #1670422
  * Username and password in IMAP URLs can now be double-quoted, so it should be
    no longer a problem if they contain delimiters like the '@' character. 
    Closes: #1640878
  * Invalid messages/files in Maildirs caused archivemail to silently stop
    processing mails and claim it's all done.  Now skip these and go ahead. 
    (Thanks Elan Ruusamäe for tracking this down.) Closes: #1783369.  
    (The Debian package has a different fix for this problem since 0.6.1-4,
    closing Debian bugs #255944 and #305902.)
  * Fixed IMAP message flag conversion which was completely broken. (Thanks
    Christian Brabandt)  Closes: Debian bug #434807
  * New option --copy: archive mail, but don't delete it from the mailbox. 
    This is mainly useful for testing purposes, and complements --delete.
    Closes: #981865, #988803, #1764851, Debian bug #434798
  * If running as root, only switch the effective uid and gid back if we have
    actually switched them before. Closes: #1762907
  * The automatic seteuid feature of archivemail is insecure and thus
    deprecated; it will be removed from later versions. 
  * Expand tilde in argument of long option --pwfile. (Thanks Christian
    Brabandt) Closes: Debian bug #434813
  * archivemail now accepts --days=0 
  * Fixed crash if --warn-duplicate is used with IMAP (Thanks Christian
    Brabandt) Closes: Debian bug #434786 (the Debian package already has a fix)
  * When converting from other formats to mbox, archivemail used to preserve
    existing 'Status' and 'X-Status' mbox headers; these are now silently
    overwritten to ensure they have correct values.
  * IMAP: if selecting the mailbox fails, archivemail detects the server's
    mailbox hierarchy delimiter, replaces slashes in the mailbox name with the
    delimiter and tries again. Closes: #1826757, Debian bug #368112

Version 0.7.0   - 2 November 2006
  * Fixed long options --filter-append and --pwfile to accept their arguments.
    Closes: #1555935
  * Fixed From_ line generation to actually look for the 'Return-path' and
    'From' headers.  Closes: #1555797
  * Fixed IMAP authentication/URL parsing, which wasn't working at all in
    v0.6.2.  Require username encoded in URL, but be flexible with the password:
    handle both --pwfile and URL-encoded password, and fallback to querying the
    user if neither is present.  Closes: #1555951
  * Convert on-the-wire CRLF to native EOL when saving messages from an IMAP
    folder.  Closes: #1555803
  * Updated man page.  This also addresses #1555951
  * Fixed unittest failure by updating --suffix testcase.  Based on analysis by
    Peter Poeml.  Thanks, Peter. 
  * Fixed invalid IMAP filter string for large messages (--size option).
    (Thanks to the anonymous bug reporter)  Closes: #863813
  * Fixed IMAP --dry-run so it doesn't download all messages that would be
    archived.  
  * Fixed IMAP --delete which didn't work at all.  (Thanks Anand)  
    Closes: Debian bug #203282
  * Terminate each message in newly written mbox with an empty line if the
    message source is not an mbox-format folder.  (Thanks  Chung-chieh Shan)
    Closes: Debian bug #250410
  * Mangle From_ in message body if the message source is not an mbox-format
    folder.  (Thanks Chung-chieh Shan)  Closes: Debian bug #250402
  * Added new option --dont-mangle to turn off From_ mangling.
  * Bumped Python dependency to version 2.3.
  * Fixed unittest TestMboxExclusiveLock which failed on Solaris.  (Thanks Paul
    Rodger)  Closes: #904652
  * Fixed unsafe creation of temporary files in the test suite.
    This addresses Debian bug #385253, and reading the BTS log, it seems this
    issue was assigned CVE-2006-4245, although I cannot find any further
    reference to that CVE.  Note that the bug was initially reported to affect
    archivemail itself, too.  This is not correct.  (Thanks Joey Hess)
    Closes: Debian bug #385253
  * Fixed cleanup of temporary files after test suite failures. 
  * Fixed dotlocking race condition. 
  * Stats are now working with IMAP.
  * Stats now report the total size of a mailbox and of the archived messages
    therefrom.  
  * Always barf if the archive destination directory is world-writable.
  * Distributing man page with the tarball again and fixed distutils setup.
    Closes: #1574720 (Thanks Grant Goodyear)
  * Improved IMAP error reporting

Version 0.6.2   - 27 June 2006
  * add -F/--filter-append option to append an arbitrary string to the IMAP 
    filter string
  * don't delete more than a certain number of messages at a time. The max 
    command len is limited. Fixes bug 942403 (Archiving large IMAP folders fails)
  * IMAP: try CRAM-MD5 login first, if that fails fallback to plain login
  * add SSL support per imaps URL (after patch by Tobias Gruetzmacher)
  * add -P/--pwfile option to supply the IMAP password, so it does not end up in 
    the shell history
  * Fix SyntaxWarning: assignment to None (bug #843890)
  * Use the archive cut date rather than the actual time with the --suffix
    option. (Thanks Manuel Estrada Sainz)

Version 0.6.1   - 31 October 2002
  * Removed a test rule that we could archive messages older than the 
    Unix epoch. Newer versions of python now give an overflow error calling
    mktime() on dates < 1970 instead of returning a negative number.

Version 0.6.0   - 3 October 2002
  * Added IMAP mailbox support. (Thanks Mark Roach)

Version 0.5.1   - 18 September 2002
  * Fixed a bug where when running archivemail as root on a non-root mailbox,
    the temporary container directory would be created as root before the
    seteuid() took place. (Thanks Jay Hesselberth)

Version 0.5.0   - 15 September 2002
  * Fixed a bug where mailbox locking would fail under Solaris. (Thanks Mark
    Sheller)
  * Fixed a bug where archiving maildir mailboxes without a 'Received Date' or
    'From' header would fail. (Thanks Hugo van der Merwe)
  * Removed yet another bug where messages dated on the Unix epoch would fail.

Version 0.4.9   - 18 August 2002
  * Fixed a bug where an exception was thrown if a message was dated exactly
    on the Unix epoch.
  * Fixed a bug where trailing slashes on the end of maildir/MH mailbox
    arguments were being used in the archive name.

Version 0.4.8   - 20 May 2002
  * Call mkdir() to create a container directory in which we can place any
    created tempfiles 

Version 0.4.7   - 9 May 2002
  * Fixed a bug where archivemail would abort if it received a date header
    with a completely blank value.

Version 0.4.6   - 6 May 2002
  * Fixed a bug where the os.rename() calls could fail if we were moving
    temporary files across different filesystems/partitions.

Version 0.4.5   - 29 April 2002
  * Fixed a bug where if you used the '--delete' option to completely clean
    an mbox mailbox you would get a python error.
  * Added a lot more testing to test_archivemail.py (test_archivemail.py is
    now 37% bigger than archivemail -- scary)
  * Added a new '--size' option which allows you to only archive messages 
    over a certain size.

Version 0.4.4   - 27 April 2002
  * Fixed a bug where the long --suffix option was not working (although the 
    short option, '-s' was).
  * Added time-based format directives to the --suffix option, so that you 
    can do things like specify --suffix='%B%Y' to create archives named
    after the current month and year
  * Added some more tests to test_archivemail.py

Version 0.4.3   - 26 April 2002
  * Fixed a couple of bugs where I was using python version 2.2 syntax that
    was giving errors in python v2.0 and v2.1. 
  * Changed the python requirements for the test script from python version
    2.0 to version 2.1. This is because the unittest module is only available
    in version 2.1 and above.

Version 0.4.2   - 24 April 2002
  * Added the ability to archive messages older than a given absolute date 
    with the new option '--date'.
  * Fixed a bug where archivemail would complain about messages older than 
    1970. Yes, someone had a 'Date' header with 1967 :)
  * Complain if the mailbox to be read does not look like a valid mbox-format
    mailbox.
  * Added a few more tests to test_archivemail.py

Version 0.4.1   - 21 April 2002
  * Don't archive messages that are flagged important unless we are given the
    --include-flagged option. 
  * Fixed a bug where when archiving messages from maildir mailboxes, we were
    not preserving the status information contained in the filename suffix to
    Status and X-Status mbox headers. This means we forgot if we had read or 
    replied to the message.
  * We now complain if an mbox-format mailbox that is being read changes in 
    size -- this should not happen, since we have locked these files, but it
    is a good sanity check.
  * Changed from using the mailbox.PortableUnixMailbox class to read mbox 
    mailboxes to the mailbox.UnixMailbox class. This fixes bugs where unquoted
    'From ' lines in the body of messages were confusing archivemail.

Version 0.4.0   - 17 April 2002
  * Added an option --no-compress to make archives but not compress them with  
    gzip.
  * Added an option --preserve-unread to not archive unread messages.
  * Added a few more unittests.

Version 0.3.2   - 13 April 2002
  * Added a lot more information to the manpage, including examples and 
    notes.
  * Fixed up the README file and archivemail usage message.
  * Added an example archivemail shell script that I run from crontab.

Version 0.3.1   - 12 April 2002
  * Stopped calling 'gzip' externally and started using the gzip library
    so that we can append to a copy of the gzip archive directly. 
  * Removed 'bzip2' and 'compress' options since they are increasing
    complexity without adding much, and needed to be called externally.
    Maybe when python gets a bzip2 library I will add back an option to 
    compress archives using bzip2.
  * Included a man page & sgml docbook source.

Version 0.3.0   - 11 April 2002
  * We now preserve the last-accessed and last-modified timestamps correctly
  * We now preserve the correct permissions on the original mailbox instead
    of always mode 600
  * Fixed a bug where lockfiles were being created that were not
    world-readable
  * Made archivemail work better when used as a python module so it can
    integrate better with unittest. (... although I still distribute it 
    without the .py extension - dodgy?)
  * Bundled a unit-testing script for archivemail 
  * Started using a distutils 'setup.py' script for installation.

Version 0.2.1   - 4 April 2002
  * Since we might not have a parse-able 'Date-Received' or 'Date' field,
    use 5 different ways to guess the date of a message. 
  * Removed the '--use-mtime' option since it is obsolete -- we will always
    use the file modification time for the message if other date-parsing
    methods fail.  
  * Check to see if we are running as root -- if so, change our
    effective userid and groupid to that of the original mailbox. This will 
    make sure any archives or tempfiles we write have the same ownership and 
    will allow the root user to do "archivemail /var/spool/mail/*"
  * Fixed a bug where if you ran 'archivemail.py foo/mbox' it would create 
    the archive file in the current directory instead of the directory 'foo'.

Version 0.2.0   - 3 April 2002
  * Added support for reading from MH mailboxes
  * Refuse to proceed if we would be making tempfiles in world-writable
    directories
  * Clamped down with lots of assert()s checking function parameters
  * Complain earlier if we do not have permission to write to the output
    directory
  * Use the 'Date' field of a message when constructing the 'From_' line
    from a maildir/MH mailbox if there is no 'Delivery-Date' field.

Version 0.1.0   - 31 March 2002
  * Initial release
