This provides support for GNUstep (via the GNUstep libraries) and Mac
OS X (via the Cocoa libraries).

+different buffer current, Emacs no longer kills that buffer
+automatically. This behavior existed in previous versions of Emacs,
+but was undocumented. To kill a buffer after write-region, give the
+variable `write-region-post-annotation-function' a buffer-local value
+of `kill-buffer'.

+*** Upgraded to MH-E version 8.1. See MH-E-NEWS for details.
** 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.
+
+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.

functions and variables (formerly used for Tamil script).
