version) include:
============================================================================
2002/12/21 (2.5.14)
* Security patch release: This release fixes a cross-site scripting
(XSS) vulnerability in m2h_text_html::filter (the HTML filter).
A specially crafted HTML message can have scripting markup get
by the script filtering done by m2h_text_html::filter.
============================================================================
2002/10/21 (2.5.13)
* Bug Fixes: See
<http://savannah.gnu.org/bugs/index.php?group_id=1968
&set=custom&advsrch=0&msort=0&report_id=105&go_report=Go
&fix_release=2.5.13&chunksz=50>
* DBFILE resource can now be set to an absolute pathname. This
allows the database file to be located in a separate location than
in the archive directory. If not an absolute pathname, then
value is treated relative to OUTDIR.
* readmail.pl updated to handle MHTML messages better. mhtxthtml.pl
changed accordingly.
* readmail.pl handling of malformed multipart messages improved.
Cases were a the terminating boundary delimiter did not exist would
generate a warning message in the converted message body that data
could not be converted. This case should now be handled so that
end of entitiy implies a terminating boundary delimiter,
(Thanks goto Randy Blaustein for providing real-world test cases).
* Fixed problem where some message attachments were "lost". This
mainly occurs when using mha-decode with the -dcd-digest option,
or if you have registered the m2h_external::filter for message/*
data types.
(Thanks goto Steve Johnson for finding this problem.)
* m2h_external::filter will now include the subject of a message
in the attachment link if saving message/* data to a file.
* m2h_external::filter properly escapes the filename parameter
when displaying it in the attachment link. This is done to
avoid any possible XSS exploits. Note, no exploits have been
reported by using the filename parameter in messages, so this
change is more of a preemptive measure.
* m2h_external::filter will fall back to a "txt" extension for
unknown text types instead of a "bin" extension.
* m2h_text_plain::filter: Removed hardcoded 'as-is' for US-ASCII
data. This is so a user could define a converter if having to deal
with mislabeled character data.
(Thanks goto Mooffie for finally finding a real-world case to not
hardcode us-ascii).
============================================================================
2002/09/03 (2.5.12)
* Strip more tags and attributes that could potentially be used for
XSS exploits in the HTML filter. This is a more of a preemptive
change since no new exploits have been reported.
* DATEFIELDS resource now supports indexed field names. For example:
<DateFields>
received[1]:received[0]:date
</DateFields>
The example says that mhonarc should check the second received
field, then the first received field, and then the first date field
to determine the date of a message.
The following is a summary of sigificant changes since 2.5.3. Please
see CHANGES in the distfile for the full list of changes.
* The following mail header fields added to list of fields that can
contain mail addresses: mail-reply-to, original-bcc, original-cc,
original-from, original-sender, original-to, resent-bcc, x-envelope.
Applicable to MAILTO, MAILTOURL, and ADDRESSMODIFYCODE resources.
* Added MHonArc::UTF8 CHARSETCONVERTER module as recommended at
<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=131512&repeatmerged=yes>.
However, module redone to use utf8 pragma in Perl where appropriate
and to remove unnecessary code. Use of module does require that
the Unicode::MapUTF8 module is installed and the utf8 pragma is
supported in the version of Perl you are using.
* Added MIMEALTPREFS resource: Content-type preferences for
multipart/alternative data. You can now tell MHonArc to use the
text/plain part over a text/html part in multipart/alternative
messages.
* Added the following resources:
IDXPGSSMARKUP Markup at the beginning of all index pages.
MSGPGSSMARKUP Markup at the beginning of all message pages.
TIDXPGSSMARKUP Markup at the beginning of all thread index pages.
Each resource will default to the value of the SSMARKUP resource
if not defined.
* Removed references to HEADER and FOOTER resources in the docs.
Resources removed in v2.5.0.
* Updated default resource layout settings in docs to use lowercase
tag names since MHonArc changed to use lowercase in defaults
in v2.4.7.
* Added NOSUBJECTTXT resource: Defines raw subject text to use
for messages that do not have a subject.
* Incorporated format=flowed support into mhtxtplain.pl contributed
by Ken Hirsch, with some minor improvements.
* mha-decode now supports the following option: -dcd-digest. This
tells mha-decode to not recursively process attached message/rfc822
and message/news entities. This option is useful to extract
out all the individual messages of a message digest.
* Added message/rfc822 and message/news to mhmimetypes.pl
content-type => extension/description hash. The extension used
is ".822".
Changes since 2.4.9 (the last pkgsrc version):
* Added 'use locale' pragmas to be applied when sorting messages.
This is considered experimental, but it appears to give better
results when sorting text that contains 8-bit-non-English
characters. This is far from any real locale support, but
hopefully it is better than nothing.
* Beefed up HTML filtering in mhtxthtml.pl to eliminate some
security exploits.
CAUTION: If you are worried about security, it is recommended
that you disable support of text/html messages in
your mail archives. There is no guarantee that
the mhtxthtml.pl library is robust enough to
eliminate all possible exploits that can occur with
HTML data.
Thanks goto Jason Molenda and Hiromitsu Takagi for spotting
more exploit cases.
* mhtxtplain.pl checks MIMEXCS if text/html data is excluded
when the htmlcheck option is specified. Seems unnecessary
because someone use excludes HTML data will probably not use
the htmlcheck option to m2h_text_plain::filter.
* Modified mail address extraction for $FROMADDR$ resource
variable to help deal with malformed From: header fields.
Thanks to Eugene Eric Kim for the recommendation.
* Fixed uudecoding support in mhtxtplain.pl to handle spaces
in filenames and \r\n EOLs. Thanks to Jordan Russell for
spotting this.
* Added ISO-8859-15 mappings. Thanks goto Jan Kraeber for the
contribution.
* Removed GIF images from distribution. All GIF images
have been converted to PNG format. Transparency of PNG
images may only be supported in the latest versions of various
graphical web browsers.
See <http://www.gnu.org/philosophy/gif.html> for reasons
why GIF images should not be used.
* Source code imported into CVS. CVS respository is currently
not available publicly. Stilling wondering if a site like
savannah.gnu.org should be used or if the respository should
be hosted independently, like at www.mhonarc.org.
* Fixed regex patterns in readmail.pl to avoid Perl warning
messages.
* Created a contrib/ directory to contain any contributed
programs imported into the MHonArc distribution. Moved
prsfrom.pl from extras/ to contrib/.
* Added Security section to FAQ. Provided more information to
question, "Why does a message get split into mulitple messages
with no headers?", mainly information contributed by users.
============================================================================
2001/11/24 (2.5.2)
(See BUGS for the list of bugs reported and fixed)
o mha-dbrecover new options:
-dbr-startnum #
The starting message number to recover data from. This
option is useful if you have many message files in a
directory, but you only want to recover a subset of the
files. If this option is not specified, the starting
number is 0.
-dbr-endnum #
The ending message number to recover data from. This
option is useful if you have many message files in a
directory, but you only want to recover a subset of the
files. If this option is not specified, all messages
starting from -dbr-startnum will be recovered.
o MSGPGBEGIN default value changed where $SUBJECTNA:72$ has
been replaced with $SUBJECTNA$. This is so default values
do not have any possible conflicts with variable-width
character sets.
============================================================================
2001/11/13 (2.5.1)
(See BUGS for the list of bugs reported and fixed)
o Added special note within the release notes about
downgrading.
o Some documentation corrections.
============================================================================
2001/10/14 (2.5.0)
[This is non-beta release of 2.5.0. See the change notes
below and for the various beta release for a complete list of
changes from the last v2.4 release.]
(See BUGS for the list of bugs reported and fixed)
o The ICONS resource has been updated to support the association
of icons at the base type level (e.g. text/*) and to specify
width and height hints. The example icon resource file
listed in an appendix of the documentation updated to
to use changes to ICONS resource.
o Formatting of attachment links within the m2hexternal.pl
filter has been updated to provide more verbose information.
Description of the format provided in the MIMEFILTERS
documentation. Also, a 'frame' filter argument is now
supported to instruct the filter to draw a frame around
the link.
o Default value for MIMEArgs has been changed to the following:
<MIMEArgs>
m2h_external::filter; inline
</MIMEArgs>
This is more concise then previous default value.
On a resource file maintenance standpoint, it is generally
best to specify filter arguments at the filter level and
not at the content-type level.
o Value of Perl's $^O variable printed with version information
for -V, -v, -help command-line options.
o The count of new messages added to archive are now printed
along with the total message count when QUIET is not active.
============================================================================
2001/09/05 (2.5.0b2)
(See BUGS for the list of bugs fixed)
o Long overdue update of ACKNOWLG file.
o New resources:
TSLICELEVELS -- Maximum depth for thread slices.
o New resource variables:
$TLEVEL$ -- Numeric level of message in thread.
o Added recognition of windows-1250 and windows-1252 charsets
into MHonArc::CharEnt and to default value of CHARSETCONVERTERS
resource. To apply to existing archives, use mha-dbedit
with examples/def-mime.mrc resource file.
o SUBJECTREPLYRXP now used to determine if "Re: " is added
when $SUBJECT$ is used within MAILTOURL.
o Code cleanup to eliminate perl -w warnings. Cleanup not
required for running MHonArc, but convenient for those that
use MHonArc with perl's -w option.
============================================================================
2001/08/26 (2.5.0b)
(See BUGS for the list of bugs fixed)
o API for MIMEFILTERS has been changed. Content filters are
now called as follows:
($html, @files) =
&filter($fields_hash_ref, $body_data_ref, $is_decoded,
$filter_args);
Paramaters:
$fields_hash_ref
A reference to hash of message/part header
fields. Keys are field names in lowercase
and values are array references containing the
field values. For example, to obtain the
content-type, if defined, you would do:
$fields_hash_ref->{'content-type'}[0]
Values for a fields are stored in arrays since
duplication of fields are possible. For example,
the Received: header field is typically repeated
multiple times. For fields that only occur once,
then array for the field will only contain one
item.
$body_data_ref
Reference to body data. It is okay for the
filter to modify the text in-place.
$is_decoded
Boolean flag if body data has been decoded.
This is normally true unless some non-standard
content-transfer-encoding is used.
$filter_args
String containing filter args as defined by
MIMEARGS resource.
Return:
The return value is still treated in the same manner as
previous releases. The first item in the return list is
the text that should printed to the message page. Any
other items in the return list are derived filenames created
by the filter. If undef, or the empty string, is returned,
readmail.pl assumes the filter was unable to filter the
data.
All the filters provided in the MHonArc distribution have
been modified to use the new calling convention.
o The HEADER and FOOTER resources are no longer supported.
o The default value of DEFRCNAME is now ".mhonarc.mrc"
("mhonarc.mrc" for Win/DOS).
o ISO8859 character set data processing now defaults to using
the MHonArc::CharEnt module. The old iso8859.pl library
is still provided for compatibility with older archives.
To update archives to use the new settings, you can run
the following command,
mha-dbedit -rcfile examples/def-mime.mrc \
-outdir /path/to/archive
where "examples/def-mime.mrc" represents the default MIME
processing resources for MHonArc provided within the MHonArc
distribution.
The new module is more efficient in memory usage by only
loading mappings for character sets actually processed. The
old iso8859.pl library preloads all mappings. Also, the
module is designed to be easily extensible for processing
any 8-bit-based character sets.
o Reference, follow-up, and derived file information of a
message is now stored in a different format in the database
(and internally). MHonArc will auto-update older archives
to the new format. The newer format should provide some
performance improvement.
o Messages with no subjects are now stored with no subjects.
In previous releases, the text "No Subject" was automatically
added as a message was parsed, hence there was no real
indicator that a message had no real subject.
A related change is that messages without subject text
are skipped in subject-based thread detection. Therefore,
a no-subject message will never be a possible follow-up,
but it is still possible for it to be an explicit follow-up
if it includes reference message-ids.
NOTE: This functionality does not apply to messages
processed by earlier versions where the text "No Subject"
was auto-applied to messages when parsed. A recreation
of an archive from the original message data would
have to be done to have new behavior applied to message
processed by earlier releases.
A messages with no subject will now have the string
"[no subject]" displayed any time the $SUBJECT$ resource
variable is used for the message.
o New resources:
FIRSTPGLINK Link markup for first page of main index.
LASTPGLINK Link markup for last page of main index.
TFIRSTPGLINK Link markup for first page of thread index.
TLASTPGLINK Link markup for last page of thread index.
TNEXTINBUTTON Button markup for next message
within a thread.
TNEXTINBUTTONIA Inactive button markup for next
message within a thread.
TNEXTINLINK Link markup for next message within
a thread.
TNEXTINLINKIA Inactive link markup for next
message within a thread.
TNEXTTOPBUTTON Button markup for first message in
the next thread.
TNEXTTOPBUTTONIA Inactive button markup for first
message in the next thread.
TPREVINBUTTON Button markup for previous message
within a thread.
TPREVINBUTTONIA Inactive button markup for previous
message within a thread.
TPREVINLINK Link markup for previous message
within a thread.
TPREVINLINKIA Inactive link markup for previous
message within a thread.
TPREVTOPBUTTON Button markup for first message in the
previous thread.
TPREVTOPBUTTONIA Inactive button markup for first
message in the previous thread.
TSLICECONTBEGIN Thread slice markup before the
continuation of a broken thread.
TSLICECONTEND Thread slice markup after the
continuation of a broken thread.
TSLICEINDENTBEGIN Thread slice markup for opening a level
when continuing a broken thread.
TSLICEINDENTEND Thread slice markup for closing a level
when continuing a broken thread.
TSLICELIEND Ending markup for a thread slice
message listing.
TSLICELIENDCUR Ending markup for a thread slice
message listing.
TSLICELINONE Thread slice markup for a missing
message in thread slice.
TSLICELINONEEND Ending markup for a missing message in
thread slice.
TSLICELITXT Markup for a thread slice message
listing.
TSLICELITXTCUR Markup for a thread slice message
listing if current message.
TSLICESINGLETXT Markup for a thread slice listing with
no follow-ups.
TSLICESINGLETXTCUR Markup for a thread slice listing with
no follow-ups if current message.
TSLICESUBJECTBEG Markup before a subject based thread
slice listing.
TSLICESUBJECTEND Markup after a subject based thread
slice listing.
TSLICESUBLISTBEG Thread slice markup for starting a
sub-thread.
TSLICESUBLISTEND Thread slice markup for ending a
sub-thread.
TSLICETOPBEGIN Thread slice markup for the root/start
of a thread.
TSLICETOPBEGINCUR Thread slice markup for the root/start
of a thread.
TSLICETOPEND Thread slice markup for the end of a
thread.
TSLICETOPENDCUR Thread slice markup for the end of a
thread if current message.
o $TSLICE$ resource variable can now take up to three arguments:
$TSLICE(<before>;<after>;<inclusive>)$
where,
<before> : Number indicated the maximum number of
message to print before the current message.
If empty, the before value specified in
TSLICE resource will be used.
<after> : Number indicated the maximum number of
message to print after the current message.
If empty, the after value specified in
TSLICE resource will be used.
<inclusive> : If `1', only messages within the current
thread will be printed. If `0', messages
from the previous and next threads can
be printed if the values for <before> and
<after> would go beyond the current thread.
o TSLICE resource updated to allow specification of default
value of inclusive flag.
o The following new message specifications can be used for
message data-related resource variables:
TNEXTIN Next message within current thread.
TNEXTTOP Start of next thread.
TPREVIN Next message within current thread.
TPREVTOP Start of previous thread.
When used as arguments to the the $BUTTON$ and $LINK$ resource
variables, the TNEXTINBUTTON(IA), TNEXTTOPBUTTON(IA),
TPREVINBUTTON(IA), TPREVTOPBUTTON(IA), TNEXTINLINK(IA),
TNEXTTOPLINK(IA), TPREVINLINK(IA), TPREVTOPLINK(IA) resources
are respectively applied.
o The use of TNEXT, TPREV (and new TNEXTTOP and TPREVTOP)
message specifications in resource variables behave more
intuitively when TREVERSE is active. If at the boundaries
of a thread, TNEXT and TPREV will reference the first
message of the next thread by date and the first message
of the previous thread by date, respectively.
o Version of MHonArc and Perl are printed when MHonArc starts
unless QUIET is active.
o mhtxtplain.pl (text/plain) filter changes:
. If the htmlcheck option is set and it is detected that
the data is HTML, an attempt is first made to use the
registered text/html filter via MIMEFILTERS. If none
is defined, mhtxthtml.pl will be used.
. When uudecode option is set, an attempt is to use
the registered decoder for uuencode via MIMEDECODERS.
If not defined, then base64::uudecode is used from
base64.pl.
o mhtxthtml.pl (text/html) filter changes:
. Elements that have URL attributes that auto-load data --
IMG, BODY, IFRAME, FRAME, OBJECT, SCRIPT, INPUT -- have the
atributes converted to 'javascript:void(0);' URLs. See new
'allownoncidurls' filter argument below for more details.
. The follow filter arguments have been added:
allownoncidurls Preserve URL-based attributes that are not
cid: URLs. Normally, any URL-based
attribute -- href, src, background,
classid, data, longdesc -- will be
converted to 'javascript:void(0);'
if it is not a cid: URL. This is to
prevent malicious URLs that verify mail
addresses for spam purposes, secretly set
cookies, or gather some statistical data
automatically with the use of elements
that cause browsers to automatically
fetch data: IMG, BODY, IFRAME, FRAME,
OBJECT, SCRIPT, INPUT.
notitle Do not print title.
o Searching for OTHERINDEXES resource files has been modified.
The following lists the search order for an OTHERINDEXES
resource file:
1. Current working directory.
2. Same directory that the first resource file was read as
specified by the RCFILE resource.
3. User's home directory.
4. Archive directory.
5. Perl's @INC.
o FIRST, LAST, TFIRST, and TLAST idx_page_spec arguments to
$PGLINK$ are now supported via the FIRSTPGLINK, LASTPGLINK,
TFIRSTPGLINK, and TLASTPGLINK resources.
o $PGLINKLIST$ resource variable changed to print entire
list of page links if no arguments are provided. To get
the entire list for thread indexes, use: $PGLINKLIST(T)$.
o Date parsing routine updated to recognize dates in the
following format: Weekday, Month DD, YYYY HH:MM Zone.
Apparently, this is useful if converting mail saved to
a file in text format from MS Outlook.
o Support for defining Perl function callbacks when a
new message header is read and just after a message body
has been converted. Documentation about the callbacks is
provided in a new API appendix section in the documentation
and is provided in comments in the example mhasiteinit.pl
provided in the examples/ directory.
o Various internal changes have been made to try to eradicate
Perl 4-based conventions. For example, the use of typeglobs to
pass by "reference" has been replaced by using real references.
Assuming nothing was screwed up, this change should be
transparent to most users (with the notable exception of the
API changes to MIMEFILTERS registered routines). However,
if you have mucked with MHonArc internals, or created custom
modifications, you may need to be aware that changes have
been made.
=======================================================================
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.
Bug Fixes
---------
See BUGS.
=======================================================================
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.)
Bug Fixes
---------
See BUGS.
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.
Bug Fixes
---------
See BUGS.
=======================================================================
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
---------
See BUGS.
=======================================================================
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:

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.
