* Emacs 19.34 is a bug-fix release with no user-visible changes.

* Changes in Emacs 19.33.

** Bibtex mode no longer turns on Auto Fill automatically.  (No major
mode should do that--it is the user's choice.)

** The variable normal-auto-fill-function specifies the function to
use for auto-fill-function, if and when Auto Fill is turned on.
Major modes can set this locally to alter how Auto Fill works.

* Editing Changes in Emacs 19.32

** C-x f with no argument now signals an error.
To set the fill column at the current column, use C-u C-x f.

** Expanding dynamic abbrevs with M-/ is now smarter about case
conversion.  If you type the abbreviation with mixed case, and it
matches the beginning of the expansion including case, then the
expansion is copied verbatim.  Using SPC M-/ to copy an additional
word always copies it verbatim except when the previous copied word is
all caps.

** On a non-windowing terminal, which can display only one Emacs frame
at a time, creating a new frame with C-x 5 2 also selects that frame.

When using a display that can show multiple frames at once, C-x 5 2
does make the frame visible, but does not select it.  This is the same
as in previous Emacs versions.

** You can use C-x 5 2 to create multiple frames on MSDOS, just as on a
non-X terminal on Unix.  Of course, only one frame is visible at any
time, since your terminal doesn't have the ability to display multiple
frames.

** On Windows, set win32-pass-alt-to-system to a non-nil value
if you would like tapping the Alt key to invoke the Windows menu.
This feature is not enabled by default; since the Alt key is also the
Meta key, it is too easy and painful to activate this feature by
accident.

** The command apply-macro-to-region-lines repeats the last defined
keyboard macro once for each complete line within the current region.
It does this line by line, by moving point to the beginning of that
line and then executing the macro.

This command is not new, but was never documented before.

** You can now use Mouse-1 to place the region around a string constant
(something surrounded by doublequote characters or other delimiter
characters of like syntax) by double-clicking on one of the delimiting
characters.

** Font Lock mode

*** Font Lock support modes

Font Lock can be configured to use Fast Lock mode and Lazy Lock mode (see
below) in a flexible way.  Rather than adding the appropriate function to the
hook font-lock-mode-hook, you can use the new variable font-lock-support-mode
to control which modes have Fast Lock mode or Lazy Lock mode turned on when
Font Lock mode is enabled.

For example, to use Fast Lock mode when Font Lock mode is turned on, put:

 (setq font-lock-support-mode 'fast-lock-mode)

in your ~/.emacs.

*** lazy-lock

The lazy-lock package speeds up Font Lock mode by making fontification occur
only when necessary, such as when a previously unfontified part of the buffer
becomes visible in a window.  When you create a buffer with Font Lock mode and
Lazy Lock mode turned on, the buffer is not fontified.  When certain events
occur (such as scrolling), Lazy Lock makes sure that the visible parts of the
buffer are fontified.  Lazy Lock also defers on-the-fly fontification until
Emacs has been idle for a given amount of time.

To use this package, put in your ~/.emacs:

 (setq font-lock-support-mode 'lazy-lock-mode)

To control the package behaviour, see the documentation for `lazy-lock-mode'.

** Changes in BibTeX mode.

*** For all entries allow spaces and tabs between opening brace or
paren and key.

*** Non-escaped double-quoted characters (as in `Sch"of') are now
supported.

** Gnus changes.

Gnus, the Emacs news reader, has undergone further rewriting.  Many new
commands and variables have been added.  There should be no
significant incompatibilities between this Gnus version and the
previously released version, except in the message composition area.

Below is a list of the more user-visible changes.  Coding changes
between Gnus 5.1 and 5.2 are more extensive.

*** A new message composition mode is used.  All old customization
variables for mail-mode, rnews-reply-mode and gnus-msg are now
obsolete.

*** Gnus is now able to generate "sparse" threads -- threads where
missing articles are represented by empty nodes.

    (setq gnus-build-sparse-threads 'some)

*** Outgoing articles are stored on a special archive server.

    To disable this:  (setq gnus-message-archive-group nil)

*** Partial thread regeneration now happens when articles are
referred.

*** Gnus can make use of GroupLens predictions:

    (setq gnus-use-grouplens t)

*** A trn-line tree buffer can be displayed.

    (setq gnus-use-trees t)

*** An nn-like pick-and-read minor mode is available for the summary
buffers.

    (add-hook 'gnus-summary-mode-hook 'gnus-pick-mode)

*** In binary groups you can use a special binary minor mode:

    `M-x gnus-binary-mode'

*** Groups can be grouped in a folding topic hierarchy.

    (add-hook 'gnus-group-mode-hook 'gnus-topic-mode)

*** Gnus can re-send and bounce mail.

    Use the `S D r' and `S D b'.

*** Groups can now have a score, and bubbling based on entry frequency
is possible.

    (add-hook 'gnus-summary-exit-hook 'gnus-summary-bubble-group)

*** Groups can be process-marked, and commands can be performed on
groups of groups.

*** Caching is possible in virtual groups.

*** nndoc now understands all kinds of digests, mail boxes, rnews news
batches, ClariNet briefs collections, and just about everything else.

*** Gnus has a new backend (nnsoup) to create/read SOUP packets.

*** The Gnus cache is much faster.

*** Groups can be sorted according to many criteria.

    For instance: (setq gnus-group-sort-function 'gnus-group-sort-by-rank)

*** New group parameters have been introduced to set list-address and
expiration times.

*** All formatting specs allow specifying faces to be used.

*** There are several more commands for setting/removing/acting on
process marked articles on the `M P' submap.

*** The summary buffer can be limited to show parts of the available
articles based on a wide range of criteria.  These commands have been
bound to keys on the `/' submap.

*** Articles can be made persistent -- as an alternative to saving
articles with the `*' command.

*** All functions for hiding article elements are now toggles.

*** Article headers can be buttonized.

    (add-hook 'gnus-article-display-hook 'gnus-article-add-buttons-to-head)

*** All mail backends support fetching articles by Message-ID.

*** Duplicate mail can now be treated properly.  See the
`nnmail-treat-duplicates' variable.

*** All summary mode commands are available directly from the article
buffer.

*** Frames can be part of `gnus-buffer-configuration'.

*** Mail can be re-scanned by a daemonic process.

*** Gnus can make use of NoCeM files to filter spam.

    (setq gnus-use-nocem t)

*** Groups can be made permanently visible.

    (setq gnus-permanently-visible-groups "^nnml:")

*** Many new hooks have been introduced to make customizing easier.

*** Gnus respects the Mail-Copies-To header.

*** Threads can be gathered by looking at the References header.

    (setq gnus-summary-thread-gathering-function
          'gnus-gather-threads-by-references)

*** Read articles can be stored in a special backlog buffer to avoid
refetching.

    (setq gnus-keep-backlog 50)

*** A clean copy of the current article is always stored in a separate
buffer to allow easier treatment.

*** Gnus can suggest where to save articles.  See `gnus-split-methods'.

*** Gnus doesn't have to do as much prompting when saving.

    (setq gnus-prompt-before-saving t)

*** gnus-uu can view decoded files asynchronously while fetching
articles.

    (setq gnus-uu-grabbed-file-functions 'gnus-uu-grab-view)

*** Filling in the article buffer now works properly on cited text.

*** Hiding cited text adds buttons to toggle hiding, and how much
cited text to hide is now customizable.

    (setq gnus-cited-lines-visible 2)

*** Boring headers can be hidden.

    (add-hook 'gnus-article-display-hook 'gnus-article-hide-boring-headers)

*** Default scoring values can now be set from the menu bar.

*** Further syntax checking of outgoing articles have been added.

The Gnus manual has been expanded.  It explains all these new features
in greater detail.

* Lisp Changes in Emacs 19.32

** The function set-visited-file-name now accepts an optional
second argument NO-QUERY.  If it is non-nil, then the user is not
asked for confirmation in the case where the specified file already
exists.

** The variable print-length applies to printing vectors and bitvectors,
as well as lists.

** The new function keymap-parent returns the parent keymap
of a given keymap.

** The new function set-keymap-parent specifies a new parent for a
given keymap.  The arguments are KEYMAP and PARENT.  PARENT must be a
keymap or nil.

** Sometimes menu keymaps use a command name, a symbol, which is really
an automatically generated alias for some other command, the "real"
name.  In such a case, you should give that alias symbol a non-nil
menu-alias property.  That property tells the menu system to look for
equivalent keys for the real name instead of equivalent keys for the
alias.

* Editing Changes in Emacs 19.31

** Freedom of the press restricted in the United States.

Emacs has been censored in accord with the Communications Decency Act.
This includes removing some features of the doctor program.  That law
was described by its supporters as a ban on pornography, but it bans
far more than that.  The Emacs distribution has never contained any
pornography, but parts of it were nonetheless prohibited.

For information on US government censorship of the Internet, and what
you can do to bring back freedom of the press, see the web site
`http://www.vtw.org/'.

** A note about C mode indentation customization.

The old (Emacs 19.29) ways of specifying a C indentation style
do not normally work in the new implementation of C mode.
It has its own methods of customizing indentation, which are
much more powerful than the old C mode.  See the Editing Programs
chapter of the manual for details.

However, you can load the library cc-compat to make the old
customization variables take effect.

** Marking with the mouse.

When you mark a region with the mouse, the region now remains
highlighted until the next input event, regardless of whether you are
using M-x transient-mark-mode.

** Improved Windows NT/95 support.

*** Emacs now supports scroll bars on Windows NT and Windows 95.

*** Emacs now supports subprocesses on Windows 95.  (Subprocesses used
to work on NT only and not on 95.)

*** There are difficulties with subprocesses, though, due to problems
in Windows, beyond the control of Emacs.  They work fine as long as
you run Windows applications.  The problems arise when you run a DOS
application in a subprocesses.  Since current shells run as DOS
