* Editing Changes in Emacs 23.1
If you change it to t, Emacs always asks for confirmation; if you
change it to nil, Emacs never asks for confirmation.
+++
+*** The rules for performing completion have been changed.
+When generating completion alternatives, Emacs now takes the
+minibuffer text after point, if any, into account: this text is
+treated as a substring of the remaining part of the completion
+alternative (i.e., the part not matched by the minibuffer text before
+point). If no completion alternatives are found this way, Emacs
+attempts to perform partial-completion. If still no completion
+alternatives are found, we fall back on the Emacs 22 rules for
+performing completion.
+
+The new variable `completion-styles' can be customized to choose your
+favorite completion style.
++++
*** When M-n in the minibuffer reaches the end of the list of defaults,
it adds the completion list to the end, so next M-n continues putting
completion items to the minibuffer. The same principle applies to
element, it wraps to the last history element, and the forward search
wraps to the first history element. When the search is terminated, the
history element containing the search string becomes the current.

** Python
*** The file etc/emacs.py now supports both Python 2 and 3, meaning
remote files, if there is no established connection to the
corresponding remote host.
+** Rmail
+
++++
+*** Rmail no longer converts the messages to Babyl format.
+Instead, it uses UNIX mbox format, both on disk and in Rmail buffers,
+and does conversion and decoding when a message is displayed.
+
+The first time you visit an Rmail file in Babyl format, Rmail
+automatically converts it to mbox format. This is a one-time
+conversion, but it can take a few minutes, depending on how fast is
+your machine and on the size of the file. You should find the rest of
+Rmail usage unaltered.
+
+However, M-x set-rmail-inbox-list now lasts only for one session
+because there is no way to save the list of inbox files in an
+mbox-format file.
+
+Also, whereas with Babyl format M-x find-file would switch to Rmail
+mode, with mbox format this is no longer the case (there being no way
+to add an "-*- rmail-*-" cookie to an mbox file). Use C-u M-x rmail
+instead.
+
+If you have written any extensions to Rmail, they are likely to need
+updating. Conceptually, the Rmail buffer that you see is no longer
+just a narrowed portion of the whole. So you cannot access the whole
+of a message (or message collection) by a simple save-restriction and
+widen. Instead, there are two buffers: the rmail-buffer, and the
+rmail-view-buffer. The former is the buffer that you see, the latter
+is invisible. Most of the time, the invisible `view' buffer contains
+the full contents of the Rmail file, and the Rmail buffer contains a
+decoded copy of the current message (with only a subset of the
+headers). In this state, Rmail is said to be `swapped'.
+
+You may find the following functions useful:
+
+`rmail-get-header' and `rmail-set-header' get or set the value of a
+message header, whether or not it is currently visible.
+
+`rmail-apply-in-message' is a general purpose function that calls a
+function (with arguments) which you specify on the full text of a given
+message. To further narrow to just the headers, search forward for "\n\n".
+
++++
+*** The new command `rmail-mime' displays MIME messages.
+It is bound to `v' in Rmail buffers and summaries. It displays plain
+text and multipart messages in a temporary buffer, and offers buttons
+to save attachments.
+
+---
+*** The command `rmail-redecode-body' no longer accepts the optional arg RAW.
+Since Rmail now holds messages in their original undecoded form in a
+separate buffer, `rmail-redecode-body' no longer encodes the original
+message, and therefore there should be no need to avoid encoding it.
+
++++
+*** The o command is now `rmail-output'. It is an all-purpose command
+for copying messages from Rmail and appending them to files. It
+handles Babyl-format files as well as mbox-format files, and it
+handles both kinds properly when they are visited in Emacs. It always
+copies the full headers of the message.
+
++++
+*** The C-o command is now `rmail-output-as-seen'. It uses
+the message as displayed, appending it to an mbox file.
+
+---
+*** The modified status of the Rmail buffer is reported in the mode-line.
+Previously, this information was hidden.
