06/10/2001 (2.4.9)
o Added the following resources:
MIMEEXCS List of content-types to exclude
from processing. Exclusion occurs
before data is passed to filters.
o mhtxtplain.pl: If decoding uuencoded data, the data will
be excluded if application/octet-stream is listed the
MIMEEXCS resource.
o mhtxthtml.pl: If a CID URL is not available, the CID URL
is no longer preserved in the converted output. The CID
URL is stripped.
o Added the following to mhmimetypes.pl content-type table:
application/ms-excel => xls:MS-Excel spreadsheet
application/ms-powerpoint => ppt:MS-Powerpoint presentation
application/ms-project => mpp:MS-Project file
The "vnd." official versions are already present, but
some application use the above.
o TODO list added to distribution.

04/13/2001 (2.4.8)
o Added the following resources:
KEEPONRMM Do not remove message files from disk
when messages are removed from the
archive.
o m2h_text_plain::filter now uses CHARSETCONVERTERS for
translating text data with a specified charset parameter.
The only exception is iso-2022-jp, which is handled directly
to properly support nourl flag.
o m2h_external::filter new arguments:
excludeexts=ext1,...
A comma separated list of message specified filename
extensions to exclude. I.e. If the filename
extension matches an extension in excludeexts, the
content will not be written. The return markup
will contain the name of the attachment, but no
link to the data. This option is best used with
application/octet-stream to exclude unwanted data
that is not tagged with the proper content-type.
The m2h_null::filter can be used to exclude content
by content-type.
o m2h_null::filter will now output a one line description
of the excluded content. This is so the reader knows that
there was message content not saved within the archive.
o m2h_text_plain::filter new arguments:
usename If extracting uuencoded data, the filename
specified should be used.
o m2h_text_html::filter new arguments:
allowcomments Preserve any comment declarations. Normally
Comment declarations are munged to prevent
SSI attacks or comments that can conflict
with MHonArc processing. Use this option
with care.
(NOTE: Comment declarations were completely stripped before,
but the regex used was known to crash perl on large comment
declarations, so a simplier expression is now used to
modify comment declarations to prevent possible attacks.)

last pkgsrc version):
10/28/2000 (2.4.7)
o Added the following options to m2h_text_plain::filter:
attachcheck Honor attachment disposition. By default,
all text/plain data is displayed inline on
the message page. If attachcheck is specified
and Content-Disposition specifies the data as
an attachment, the data is saved to a file
with a link to it from the message page.
htmlcheck Check if message is actually an HTML message
(to get around abhorrent MUAs). The message
is treated as HTML if the first non-whitespace
data looks like the start of an HTML document.
o FROMFIELD resource default value is now:
from:mail-reply-to:reply-to:return-path:apparently-from:
sender:resent-sender
The change is the addition of "mail-reply-to."
o Added the following resource variables:
$MSGTORDNUM$ Ordinal number of message in current
thread.
o Added the following resource variable message specificiers:
TEND Last message of current discussion
thread.
TTOP Top/root message of current discussion
thread.
o Changes to readmail.pl:
- %Cid hash keys are now URLs. Content-Ids are denoted
as "cid:..." Hash also contains Content-Location values
of message parts. This allows filters (like the HTML
filter) to check for external URL references where
the data for the reference is included with the message.
- More robust handling of malformed multipart messages.
o The null filter is applied to application/ms-tnef by default.
o Lowercase tag names are now used in default resource values
that contain HTML markup.
o Bug fixes to the documentation.

04/24/2000 (2.4.6)
o Stricter check is made when decoded quoted-printable data.
An escape sequence is only converted to a raw character if
a it is a valid escape sequence. I.e. Any '=' not followed
by two hexadecimal characters is left as-is.
o Call to Digest::MD5::md5_hex() wrapped in eval block in
case of bad installations of Digest::MD5 module.

=======================================================================
02/14/2000 (2.4.5)
Enhancements/Changes
--------------------
o Following changes to m2h_text_html::filter:
- All comment declarations are removed. This avoid
potential SSI attacks and declarations that may conflict
with MHonArc.
- Additional tags have been added to the to-strip list
to avoid potential client-side scripting attacks. See
MIMEFILTERS docs for list.
- Added "nofont" option to strip out any <font> tags.
o Added application/x-bzip2 to known mime types (mhmimetypes.pl).
o Simple modification to get_time_from_date() in mhutil.pl to
handle abhorrent case of message date using a 2 digit year.
o Under VMS, the default lock file name has been changed to
"mhonarc_lck" for directory based locking will work.
o mhonarc::htmlize/entify now translates the double-quote
character (") to ".
o Added VARREGEX resource to allow customization of resource
variable matching. Mainly for use with resource files written
on multibyte charsets like SJIS. Use with caution.
Bug Fixes
---------

=======================================================================
10/01/1999 (2.4.4)
Enhancements/Changes
--------------------
o Added the following resources:
MIMEDECODERS Content-Transfer-Encoding decoding
functions.
o Added the following resource variables:
$PGLINKLIST$ Print out a list of index page links.
o New content filter for message/external-body.
o Message/delivery-status content handled by mhtxtplain.pl
o Support for "Zone[+-]DDDD" timezone specification.
o MAILparse_parameter_str() function added to readmail.pl.
Function supports parsing parameter value strings with support
for RFC 2184 extensions. Function added to provide
support for message/external-body filter.
Bug Fixes
---------
See BUGS.
=======================================================================
08/15/1999 (2.4.3)
Enhancements/Changes
--------------------
o Added the following resources:
POSIXSTRFTIME Use POSIX::strftime() or not for
processing time format strings
o The "latin[1-6]" character sets defined in the default
value of CHARSETCONVERTERS. iso8859::str2sgml modified
to use proper iso8859 map for specified latin[1-6]
specification.
o The text/html filter now strips out scripting markup by
default. To allow scripting markup to be preserved, the
"allowscript" option can be used.
o Unknown media-types are now treated as application/octet-stream,
which will invoke the application/octet-stream filter.
Because of this, an explicit entry for application/octet-stream
has been added to the default value of MIMEFILTERS.
o If in a multipart/alternative entity, and no known media-types
exists, the last part is treated as application/octet-stream.
Bug Fixes
---------
See BUGS.
=======================================================================
08/11/1999 (2.4.2)
Enhancements/Changes
--------------------
o Added the following resources:
STDIN Source for standard input
o Added the following resource variables:
$ENV$ Print an environment variable
o Added support for decoding uuencoded data within text
messages in mhtxtplain.pl. Decoding activated via the
"uudecode" option.
o For processing time format strings, POSIX::strftime() is
used, if available. If not, MHonArc implementation is
used.
o The default value of FROMFIELDS now includes "return-path".
o Description section moved before Options section in -help
message.
Bug Fixes
---------
See BUGS.
=======================================================================
07/25/1999 (2.4.1)
Enhancements/Changes
--------------------
o Added the following resources:
MSGEXCFILTER Perl expressions for excluding
messages from archive.
SAVERESOURCES Flag if resource values should be
saved in database.
o Added the following resource variables:
$HTMLEXT$ Value of HTMLEXT resource.
o Documentation corrections an additions.
o Use of typeglobs removed from mhdb.pl.
o mhtime.pl explicitly defined in mhonarc package.
Bug Fixes
---------

=======================================================================
06/25/1999 (2.4.0)
Enhancements/Changes
--------------------
o Added the following resources:
ADDRESSMODIFYCODE Perl expressions to apply to addresses
during message header conversion.
CHECKNOARCHIVE Check "no archive" flag in messages.
LOCKMETHOD The type of archive locking performed.
SPAMMODE Perform actions to deter email address
harvesters.
SSMARKUP Markup at the *very* beginning of any
generated page.
STDOUT Destination of stdout messages/data.
STDERR Destination of stderr messages/data.
SUBJECTTHREADS To check, or not to check, subjects when
computing threads.
o Added the following resource variables:
$FROMADDRNAME$ Username portion of From email address.
$FROMADDRDOMAIN$ Domain portion of From email address.
$TOADDRNAME$ Username portion of an email address
(applicable in MAILTOURL only).
$TOADDRDOMAIN$ Domain portion of an email address
(applicable in MAILTOURL only).
o A new utility program: mha-decode. The program functions
as a MIME message decoder. Can be used against mail folders
or single messages.
o The "PARENT" argument to applicable resource variables is now
called "TPARENT". This change should not affect anyone since
the "PARENT" argument did not work properly in previous
releases.
o SUBJECTHEADER and HEADBODYSEP resource changes will now affect
existing messages that are edited during normal operations or
via EDITIDX. Note, messages created from old versions of
MHonArc may not be affected.
o The default TIMEZONES settings now has a more complete list.
o Timezone acronym settings now support [+-]HHMM specifications.
o Support for ISO-2022-JP encoded strings in message headers
is now supported. It does assume that HTML viewer supports
ISO-2022-JP.
o If Digest::MD5 is installed, md5_hex() will be used to create
message-ids for messages without message-ids. This allows
MHonArc to ignore non-message-id archived messages in ADD mode.
The MD5 digest is computed only on message header for efficieny.
If Digest::MD5 is not installed, a message-id will still be
assigned if none present, but MHonArc will not be able to
detect if message has already been archived in subsequent ADD
operations.
o Text/html filter supports the "noscript" option. If
specified, any script-related markup will be removed.
This provides added security to avoid sites being compromised
with foreign client-side scripting.
o Added the following options to mhexternal.pl (the save-to-file
filter): forceattach, forceinline, and inlineexts.
o Recognize mailing list headers as defined by RFC 2369 and
hyperlink URLs listed.
o If no boundaries exist in a multipart message (even though
a boundary is defined in the header), MHonArc will treat
the entire body as the first part. This prevents "unable
to process" warnings.
o The "<!--X-From" comment declaration at the top of converted
messages is now munged by a modified ROT13 to facilitate
anti-spam-bot measures, but still provide the "From"
information for mha-dbrecover.
o When editing message pages, the new version of the page is now
created as a temporary file and then if successfully created,
it will get renamed to its proper name. This help avoids "losing"
a message page if there is an error during page editing. The
same method is applied to the dumping of DBFILE.
o Message sorting modified to improve sorting performance when
sorting by subject and author.
o URL matching expression in mhtxtplain.pl modified to handle
'&' characters.

10/25/1998 (2.3.1)
Enhancements/Changes
--------------------
Please read the RELNOTES file for important information regarding
upgrading to v2.2.x, or later, from pre-v2.2 releases.
o Support for MHTML. I.e. An HTML document that references data
included as other parts to the mail message, will be converted
so the data will be shown where referenced. Before, all
referenced data was shown at the end of the message.
o Auto-computing the name for attachments no longer caches
data, so performance may decrease when processing MIME
messages. This change is required since multiple filters can
now write data to files and not all to the same directory (a
common utility function now exists for writing data to a file).
Also, it avoids behavioral problems with custom front-ends
that operate on multiple archives in a single process.
o Changes to readmail.pl inorder to support MHTML. Changes
done should help the handling of other multipart/related
data types.

10/10/1998 (2.3.0)
o Perl 5 is now required to run MHonArc. Although the code
base is still "Perl 4-style", many changes made use of Perl 5
constructs.
o New utility programs added to the dustribution:
mha-dbedit - Make resource/db changes w/o touching
pages.
mha-dbrecover - Rebuild database from HTML message
files.
o Many resource variables have been changed to take arguments
to control what values the variables will expand to. Because,
of this, many variables are now deprecated. However, old
forms of resource variables are still recognized.
See the documentation for more information on resource
variables (a new section on resource variables has been
added to the documentation) and the newer syntax.
o New resources:
AFS - Skip archive directory permission check
ANNOTATE - Annotate message(s).
LOCK - To lock, or not to lock.
MSGPGS - Print, or not, message pages.
NOTE - Annotate markup.
NOTEIA - Inactive annotate markup.
NOTEDIR - Directory where annotations are located.
NOTETEXT - Annotation text.
PAGENUM - Page to output when using GENIDX with
MULTIPG.
READDB - Just load the database
(useful for application front-ends).
USELOCALTIME - Use localtime to determine day groups in
date index listing.
o New resource variables:
$DDMMYYYY$ - Day/Mon/Year(4 digit)
$MMDDYYYY$ - Mon/Day/Year(4 digit)
$MSG$ - Filename of message page
$SORTTYPE$ - Type of sort in use for main index
$TSORTTYPE$ - Type of sort in use for thread index
$YYYYMMDD$ - Year(4 digit)/Mon/Day
Note, many other variables have been changed. See docs for
more information.
o Added "J" modifier for resource variables. When specified,
escapes quote characters so expanded values can be used
within JavaScript strings.
o Added "usenameext" option to mhexternal.pl filter. When
specified, mhexternal.pl will use the filename specified in
the message for determining the filename extension to use.
o The -rcfile option can be specified multiple times. Resource
files specified are read in the order specified.
o The -definevars options has been deprecated in favor of
-definevar (no ending 's'). -definevar can be specified
multiple times on the command-line. The usaage of it is
exactly the same as -definevars. The -definevars is still
supported for backwards compatibility.
o The -perlinc option can be specified multiple times.
o For the mhtxtplain.pl filter, the TARGET attribute for links is
now specified only if the target option is specified.
o MHonArc is now smarter when the RMM resource is used. MHonArc
will now only update pages that are required when messages
are removed instead of doing a force update on all pages.
RMM operations will now perform much faster.
o Subject based replies are *no longer* treated as a separate
"group" when printing thread index pages. I.e. Subject based
replies no longer cause a separate TSUBLISTBEG and TSUBLISTEND
to be invoked. Before, it was a problem if the HTML OL
element was used. OL numbering would restart when subject
based replies were printed.
o GENIDX now supports the use of MULTIPG (w/IDXSIZE).
o MHonArc uses rename instead of file copying when editing
pages. Should provide a speed increase when editing archive
pages.
o Reason when a file cannot be opened or created is printed
($! is now included in the error message).
o If unable to lock an archive (and -force not specified),
MHonArc will now return an exit status of 75 (EX_TEMPFAIL).
This is for the benefit of MTAs (like sendmail) where
MHonArc is called via an alias.
o Some changes to code to make it suitable for MHonArc to be
embedded into other Perl programs. The most significant
changes was to make it possible to process more than one
archive in a single process instance (note, archives can
only be processed in sequence and not in parallel). Now it
easier to write different application front-ends to MHonArc.
o Some other code cleanup in the hopes to improve performance.

- New, optional Makefile variable HOMEPAGE, specifies a URL for
the home page of the software if it has one.
- The value of HOMEPAGE is used to add a link from the
README.html files.
- pkglint updated to know about it. The "correct" location for
HOMEPAGE in the Makefile is after MAINTAINER, in that same
section.
