	      <Differences between Mew 3.3 and Mew 3.2>

* Some bug fixes.

	      <Differences between Mew 3.2 and Mew 3.1>

* If SSL/SSH is used for message retrieval by POP/IMAP/NNTP,
  it is notified in mode line ("Sec" or a lock image).
* Supporting Emacs 21.3.50's native UTF-8.
* Translation between Latin 0 and Latin 1.
* A certificate of an SSL server can be verified. For this, "stunnel"
  v3 and v4 are supported and support for "openssl s_client" is
  obsoleted.
* Supporting X-Face: on Emacs 21. To use X-Face: on any Emacsen,
  install "uncompface" command and the "netpbm" package.
* Obsoleting the following variables:
	mew-noreplyto-to-list
	mew-noreplyto-cc-list
	mew-replyto-to-list
	mew-replyto-cc-list
	mew-fromme-to-list
	mew-fromme-cc-list
  And defining the following variables:
	mew-reply-all-alist
	mew-reply-sender-alist
	mew-reply-fromme-alist
  This change enables support for NetNews and non-standard fields
  such as Mail-Folloup-To:.
* New commands in Summary mode.
	"\", "M-\", "m/"
* Many bug fixes.

	      <Differences between Mew 3.1 and Mew 2.2>

* Supporting Darwin.
* The structure of folder list is changed. Type "1Z" once after
  upgrading to Mew 3.1
* You can enter folder search mode by typing C-s and C-r in
  minibuffer.
* Off-line version of "x", namely "lx", is introduced.
* "x" became much faster thanks to a new algorithm of mew-dir-messages().
* A new range "sync" is defined.
* IMAP and NNTP are supported.
* +mdrop is renamed to $inbox.

	      <Differences between Mew 2.2 and Mew 2.1>

* mew-summary-toggle-8bit is bound to "z8" instaed of "8".
* "0"-"9" are bound to digit-argument. So, for example, we can type
  "10d" instead of "C-u10d".
* yes-or-no-p is replaced by y-or-n-p.
* Minor bug fixes.

	      <Differences between Mew 2.1 and Mew 2.0>

* XML is well supported.

* "c" in Summary works like "copy" (by specifying the current folder)
  while "o" does like "move".

* "," and C-cC-i are integrated. Use "," to display a part as it is.
  C-cC-i now acts like view-file.

* Both ":" and C-cC-l is now friendly for ":".

* +mdrop is implemented. You can remove messages on your POP server
  visually.

* Sort (s) and pack (O) became much faster.

* contrib/incdir now moves messages in the "cur" directory as well as
  the "new" directory if the "-a" option is specified.

* The "Type 'I'" message is displayed in the minibuffer, not in the body
  of a message marked with 'T'.

* The "Type 'T'" message is displayed in the minibuffer when CT: of an
  attach file is unknown and the default CT: is chosen.

* mew-case-guess-when-composed works well now.

* "Sort region" (C-uS) now revives.

* A header for a Bcc: message is now well-prepared.

* mew-thread-column is now obsoleted. Put 't' in mew-scan-form to
  specify the position of thread indentation.

* Asking Subject: before "Really send this message? ". And asking Fcc:
  if folders do not exist.

* The "phrase:addr1,addr2;" notation is allowed in Addrbook if and
  only if it doesn't recurse when expanded.

* Some workaround for broken POP servers.

* Many other small bug fixes.

	       <Differences between Mew 2 and Mew 1.94>

* Mew 2 has thrown away Emacs 19, Mule 2.3, XEmacs 20.4.

* Mew 2 has thrown away IM and is being implemented purely by Elisp
  with two C commands, 'mewencode' and 'mewls'.

* Thread is supported. The key bindings of most thread commands 
  start with "t". For example, typing "tt" makes thread.

* Both Multipart/Alternative and Multipart/Related are supported.
  Use ":" to display the entire structure.

* Sophisticated POP support. POP biff is supported.

* 8bit clean. If mew-use-8bit is non-nil, 8bit charset in a body is
  sent without any MIME encoding(i.e. CTE: 8bit).  If this is nil,
  8bit charset in a body is sent with an appropriate MIME
  encoding(e.g. CTE: quoted-printable).  Also, 8bit messages to be
  attached are converted into 7bit.

  8bit messages to be signed are also converted into 7bit. This is
  required by the Multipart/Signed spec.

  mew-use-8bit is nil by default to avoid accidents.

* Preview. Typing C-cC-m in Draft mode puts the composed message to
  +queue. You can preview messages to be send in +queue with 
  Summary mode.	

  If you are in Summary mode, typing C-cC-c sends all messages in
  +queue. "i" in Summary mode also flushes all messages in +queue
  since mew-auto-flush-queue is default to t.

  Typing C-cC-c in Draft sends the draft without preview.

* MIME editor. Typing "E" (i.e. reediting) in Summary mode leads you
  Draft mode. If the target is multipart, attachments are prepared.

* In attachments, you can specify charset both for input and output.
  "C" specifies the charset parameter for a Text/* object.  
  "I" specifies a input coding-system for a text file.

* Header mode is created for resending and sending the same content
  to different destinations.

* C-cC-l makes use of autoconf of a specified language.

* Mew 2 is liberal for many kinds of broken messages.

		 <Differences between 1.94 and 1.93>

* Auto input-method selection. Typing C-cC-y or C-cC-t in Draft mode
  automatically selects input-method on X/Emacs 20 or later.

  For example, Germany can be represented by both iso-8859-1 and
  iso-8859-1. When you received a Germany message in iso-8859-2, it
  would be nice if latin-2-postfix is selected for input-method. To
  implement this, put the following to your .emacs.

	(setq mew-charset-input-method-alist
	      '(("iso-8859-1" . "latin-1-postfix")
		("iso-8859-2" . "latin-2-postfix")))

* "y" in Summary mode is now able to save the raw format of message
  (i.e. header fields are not decoded). You can safely forward saved 
  messages.

* Multiple "inbox"es with IM Config are supported.

* "D" in Summary mode removes all messages in the +trash folder.

* Summary mode is now really multi-lingualized thanks to IM.

* Aliases and Petname are integrated into Addrbook. To register expansion
  rules and/or personal information, type [C-u]C-cC-a in Summary
  mode.

* The cache prefetch mechanism is implemented. You can read messages
  very quickly in Summary mode.

* Thanks to the cache prefetch mechanism, the non-MIME analysis sub-mode,
  which is provided for rapid reading, becomes meaningless. So, M-a was
  throw away. Use "," if you want to see a message in the raw format.

* GNUPG support. To select PGPv2/PGPv5/GNUPG, type C-cC-v in Summary 
  mode.

* Imget's password and PGP passphrase can be cached. You can now survive
  without impwagent.
  Set mew-use-cached-passwd t.
  Set mew-use-pgp-cached-passphrase to t.

* C-c{C-s,C-p,C-b,C-r} can work even if draft contains attachments.

* Automatic PGP protection for all drafts or drafts replying to 
  encrypted messages is supported. 
  See mew-protect-privacy-{always,encrypted}.

* C-cC-p in Summary mode can handle old-fashioned PGP messages.

* "." can decrypt messages which you failed to decrypt before.

* Unknown Multipart/{Signed,Encrypted} is treated as a single part.

* C-u Z saves the update folder file to ~/Mail/.folders. So, Mew can 
  assume that this file exist by default. Concludingly the bootstrap
  becomes faster. mew-use-folders-file-p is now default to `t'. 

* You can customize Mew so that the directory previously used is 
  preserved. See, mew-{summary,draft}-preserve-dir. See also
  mew-summary-trace-directory.

* You can display text/html by a running netscape.
  Put the following in .emacs.
	(setq mew-prog-text/html-arg-hack 'mew-prog-text/html-netscape-remote)

* Range is asked only when you interactively execute "s".

* The key binding of FIB commands were changed with the C-cC-f prefix.

* Getting along with the mail-user-agent convention.

* Many IMAP4-friendly hacks.

* Many many bug fixes. And many many optimizations.



		 <Differences between 1.93 and 1.92>

* Copyright of Mew conforms ``AS IS'' instead of GPL2.

* Mew now supports IMAP4 and qmail mailbox.

* immv, imrm, and imclean are implemented by Elisp. So, "x" in Summary
  mode became much faster. Other commands became faster as well.

* Multipart format in Summary mode and Draft mode are integrated.

* Neat support for IM Config. Please refer to info for more information.

* mew-opt-highlight-* -> mew-use-highlight-*.

* mew-field-{,in}visible were obsoleted. Use mew-field-spec instead.

* Hankaku kana is converted into zenkaku kana if exists.

* Safely ignores unknown charset in a header.

* message/partial and text/html are supported.

* Ad-hoc PGP 5 support.

* Content-Disposition: support.

* Neat reporting mechanism of PGP/MIME.

* Many many bug fixes.

		 <Differences between 1.93 and 1.70>

* Mew uses IM Perl5 instead of MH. Mew will never support MH again.

* Mew works on OS/2, Win95, and WNT as well as on UNIX.

* Mew doesn't ask you to input y or n in Summary mode though it used
  to do so. Please follow instructions which Mew displays.

* Deleting messages on Summary mode(i.e. the D mark) means refiling to
  the +trash folder. If in +trash folder, messages marked with 'D' are
  really removed. You can customize this action. See
  mew-msg-rm-policy for details.

* "N" and "P" in Summary mode move the cursor onto only messages
  marked with '*'. To skip parts, call "n" or "p" with "C-u".

* The default folder name of draft changed from "+drafts" to "+draft"
  so that its length became equal to "+inbox" and "+trash".

* Some key-bindings in Draft mode were changed to keep C-c "key" for
  users.

	C-cM  -> C-cC-a
	C-cu  -> C-cC-l
	C-cy  -> C-cC-t

* C-cC-u(undo) in Draft mode works for any kinds of messages. For this
  reason, mew-mime-compose-folder-delete is set 'delete by default.

* PGP/MIME became very stable. And verification message turned more
  informational.

	e.g. "No public key" -> "No his/her public key"

  C-cC-u works even for PGP shortcuts.

* Refile scheme was changed much.

	mew-auto-folder-alist             -> mew-refile-guess-alist
	mew-refile-folder-guess-functions -> mew-refile-guess-control

* Pick interface(for "?", "/", and "V") was changed. Examples are below:

	to=mew-dist
	to=kazu & cc=kazu

* Burst("B") on Summary mode is now really cool.

* Subject is displayed for Message/Rfc822 if Content-Description: is empty.

* "C-uZ" on Summary mode saves Mail/.folders if mew-use-folders-file-p. 
  If mew-use-folders-file-p is t, Mew loads Mail/.folders at boot time.

* Many similar codes were integrated.

* Some function names were changed.

	mew-mark-process-all-folders -> mew-mark-clean-up-all
	(Remove kill-emacs-hook from .emacs if it contains
	mew-mark-process-all-folders.)

* Some variables were changed.

	Each members of mew-folders-ignore must start with "+" or "=".
	Value of mew-folders-default-folder must start with "+" or "=".

* Support RFC 2047(aka MIME header encoding/decoding) precisely.

* Color is now used by default. Remove configurations concerned with
  fonts from each hooks!.
