Fonts containing +oversized characters, i.e. characters larger than the logical height +of a font can be used. Images of various formats can be displayed in +the text. + +** Emacs has a new face implementation. + +The new faces no longer fundamentally use X font names to specify the +font. Instead, each face has several independent attributes--family, +height, width, weight and slant--that it may or may not specify. +These attributes can be merged from various faces, and then together +specify a font. + +Faces are supported on terminals that can display color or fonts. +These terminal capabilities are auto-detected. Details can be found +under Lisp changes, below. + +** Emacs can display faces on TTY frames. + +Emacs automatically detects terminals that are able to display colors. +Faces with a weight greater than normal are displayed extra-bright, if +the terminal supports it. Faces with a weight less than normal and +italic faces are displayed dimmed, if the terminal supports it. +Underlined faces are displayed underlined if possible. Other face +attributes such as `overline', `strike-through', and `box' are ignored +on terminals. + +The command-line options `-fg COLOR', `-bg COLOR', and `-rv' are now +supported on character terminals. + +** New default font is Courier 12pt under X. + ++++ +** Emacs now resizes mini-windows if appropriate. + +If a message is longer than one line, or minibuffer contents are +longer than one line, Emacs can resize the minibuffer window unless it +is on a frame of its own. You can control resizing and the maximum +minibuffer window size by setting the following variables: + +- User option: max-mini-window-height + +Maximum height for resizing mini-windows. If a float, it specifies a +fraction of the mini-window frame's height. If an integer, it +specifies a number of lines. + +Default is 0.25. + +- User option: resize-mini-windows + +How to resize mini-windows. If nil, don't resize. If t, always +resize to fit the size of the text. If `grow-only', let mini-windows +grow only, until they become empty, at which point they are shrunk +again. + +Default is `grow-only'. + +** LessTif support. + +Emacs now runs with the LessTif toolkit (see +). You will need version 0.92 or later. + +** LessTif/Motif file selection dialog. + +When Emacs is configured to use LessTif or Motif, reading a file name +from a menu will pop up a file selection dialog if `use-dialog-box' is +non-nil. + +** Toolkit scroll bars. + +Emacs now uses toolkit scroll bars if available. When configured for +LessTif/Motif, it will use that toolkit's scroll bar. Otherwise, when +configured for Lucid and Athena widgets, it will use the Xaw3d scroll +bar if Xaw3d is available. You can turn off the use of toolkit scroll +bars by specifying `--with-toolkit-scroll-bars=no' when configuring +Emacs. + +When you encounter problems with the Xaw3d scroll bar, watch out how +Xaw3d is compiled on your system. If the Makefile generated from +Xaw3d's Imakefile contains a `-DNARROWPROTO' compiler option, and your +Emacs system configuration file `s/your-system.h' does not contain a +define for NARROWPROTO, you might consider adding it. Take +`s/freebsd.h' as an example. + +Alternatively, if you don't have access to the Xaw3d source code, take +a look at your system's imake configuration file, for example in the +directory `/usr/X11R6/lib/X11/config' (paths are different on +different systems). You will find files `*.cf' there. If your +system's cf-file contains a line like `#define NeedWidePrototypes NO', +add a `#define NARROWPROTO' to your Emacs system configuration file. + +The reason for this is that one Xaw3d function uses `double' or +`float' function parameters depending on the setting of NARROWPROTO. +This is not a problem when Imakefiles are used because each system's +image configuration file contains the necessary information. Since +Emacs doesn't use imake, this has do be done manually. + ++++ +** Automatic Hscrolling + +Horizontal scrolling now happens automatically if +`automatic-hscrolling' is set (the default). This setting can be +customized. + +If a window is scrolled horizontally with set-window-hscroll, or +scroll-left/scroll-right (C-x <, C-x >), this serves as a lower bound +for automatic horizontal scrolling. Automatic scrolling will scroll +the text more to the left if necessary, but won't scroll the text more +to the right than the column set with set-window-hscroll etc. + ++++ +** Tool bar support. + +Emacs supports a tool bar at the top of a frame under X. For details +of how to define a tool bar, see the page describing Lisp-level +changes. Tool-bar global minor mode controls whether or not it is +displayed and is on by default. The appearance of the bar is improved +if Emacs has been built with XPM image support. Otherwise monochrome +icons will be used. + +To make the tool bar more useful, we need contributions of extra icons +for specific modes (with copyright assignments). Contributions would +also be useful manually to touch up some of the PBM icons. + ++++ +** Tooltips. + +Tooltips are small X windows displaying a help string at the current +mouse position. The Lisp package `tooltip' implements them. You can +turn them off via the user option `tooltip-mode'. + +Tooltips also provides support for GUD debugging. If activated, +variable values can be displayed in tooltips by pointing at them with +the mouse in source buffers. You can customize various aspects of the +tooltip display in the group `tooltip'. + ++++ +** When using a windowing terminal, each Emacs window now has a cursor +of its own. By default, when a window is selected, the cursor is +solid; otherwise, it is hollow. The user-option +`show-cursor-in-non-selected-windows' controls how to display the +cursor in non-selected windows. If nil, no cursor is shown, if +non-nil a hollow box cursor is shown. This option can be customized. + +** Fringes to the left and right of windows are used to display +truncation marks, continuation marks, overlay arrows and alike. The +foreground, background, and stipple of these areas can be changed by +customizing face `fringe'. + +** The mode line under X is now drawn with shadows by default. +You can change its appearance by modifying the face `mode-line'. +In particular, setting the `:box' attribute to nil turns off the 3D +appearance of the mode line. (The 3D appearance makes the mode line +occupy more space, and thus might cause the first or the last line of +the window to be partially obscured.) + +The variable `mode-line-inverse-video', which was used in older +versions of emacs to make the mode-line stand out, now defaults to nil, +and its use is deprecated. + ++++ +** Mouse-sensitive mode line. + +Different parts of the mode line under X have been made +mouse-sensitive. Moving the mouse to a mouse-sensitive part in the mode +line changes the appearance of the mouse pointer to an arrow, and help +about available mouse actions is displayed either in the echo area, or +in the tooltip window if you have enabled one. + +Currently, the following actions have been defined: + +- Mouse-1 on the buffer name in the mode line switches between two +buffers. + +- Mouse-2 on the buffer-name switches to the next buffer, and +M-mouse-2 switches to the previous buffer in the buffer list. + +- Mouse-3 on the buffer-name displays a buffer menu. + +- Mouse-2 on the read-only or modified status in the mode line (`%' or +`*') toggles the status. + +- Mouse-3 on the mode name displays a minor-mode menu. + ++++ +** Hourglass pointer + +Emacs can optionally display an hourglass pointer under X. You can +turn the display on or off by customizing group `cursor'. + ++++ +** Blinking cursor + +M-x blink-cursor-mode toggles a blinking cursor under X and on +terminals having terminal capabilities `vi', `vs', and `ve'. Blinking +and related parameters like frequency and delay can be customized in +the group `cursor'. + ++++ +** New font-lock support mode `jit-lock-mode'. + +This support mode is roughly equivalent to `lazy-lock' but is +generally faster. It supports stealth and deferred fontification. +See the documentation of the function `jit-lock-mode' for more +details. + +Font-lock uses jit-lock-mode as default support mode, so you don't +have to do anything to activate it. + ++++ +** The default for user-option `next-line-add-newlines' has been +changed to nil, i.e. C-n will no longer add newlines at the end of a +buffer by default. + +** The and keys now move to the beginning or end of the +current line, respectively. C- and C- move to the +beginning and end of the buffer. + +** Emacs now checks for recursive loads of Lisp files. If the +recursion depth exceeds `recursive-load-depth-limit', an error is +signaled. + +** When an error is signaled during the loading of the user's init +file, Emacs now pops up the *Messages* buffer. + ++++ +** Emacs now refuses to load compiled Lisp files which weren't +compiled with Emacs. Set `load-dangerous-libraries' to t to change +this behavior. + +The reason for this change is an incompatible change in XEmacs' byte +compiler. Files compiled with XEmacs can contain byte codes that let +Emacs dump core. + +** Toggle buttons and radio buttons in menus. + +When compiled with LessTif (or Motif) support, Emacs uses toolkit +widgets for radio and toggle buttons in menus. When configured for +Lucid, Emacs draws radio buttons and toggle buttons similar to Motif. + +** The menu bar configuration has changed. The new configuration is +more CUA-compliant. The most significant change is that Options is +now a separate menu-bar item, with Mule and Customize as its submenus. + +** Item Save Options on the Options menu allows saving options set +using that menu. + ++++ +** Highlighting of trailing whitespace. + +When `show-trailing-whitespace' is non-nil, Emacs displays trailing +whitespace in the face `trailing-whitespace'. Trailing whitespace is +defined as spaces or tabs at the end of a line. To avoid busy +highlighting when entering new text, trailing whitespace is not +displayed if point is at the end of the line containing the +whitespace. + ++++ +** C-x 5 1 runs the new command delete-other-frames which deletes +all frames except the selected one. + +** The new user-option `confirm-kill-emacs' can be customized to +let Emacs ask for confirmation before exiting. + ++++ +** Highlighting of mouse-sensitive regions is now supported in the +MS-DOS version of Emacs. + +** The header line in an Info buffer is now displayed as an emacs +header-line (which is like a mode-line, but at the top of the window), +so that it remains visible even when the buffer has been scrolled. +This behavior may be disabled by customizing the option +`Info-use-header-line'. + ++++ +** The recommended way of using Iswitchb is via the new global minor +mode `iswitchb-mode'. + ++++ +** Just loading the msb package doesn't switch on Msb mode anymore. +If you have `(require 'msb)' in your .emacs, please replace it with +`(msb-mode 1)'. + +** Polish, Czech, German, and French translations of Emacs' reference card +have been added. They are named `pl-refcard.tex', `cs-refcard.tex', +`de-refcard.tex' and `fr-refcard.tex'. Postscript files are included. + +** An `Emacs Survival Guide', etc/survival.tex, is available. + +** A reference card for Dired has been added. Its name is +`dired-ref.tex'. A French translation is available in +`fr-drdref.tex'. + ++++ +** C-down-mouse-3 is bound differently. Now if the menu bar is not +displayed it pops up a menu containing the items which would be on the +menu bar. If the menu bar is displayed, it pops up the major mode +menu or the Edit menu if there is no major mode menu. + +** Variable `load-path' is no longer customizable because it contains +a version-dependent component. + +** The new user-option `delete-key-deletes-forward' can be set to +let the Delete function key delete forward instead of backward. + +On window systems, the default value of this option is chosen +according to the keyboard used. If the keyboard has both a Backspace +key and a Delete key, and both are mapped to their usual meanings, the +option's default value is set to t, so that Backspace can be used to +delete backward, and Delete can be used to delete forward. + +If not running under a window system, setting this option accomplishes +a similar effect by mapping C-h, which is usually generated by the +Backspace key, to DEL, and by mapping DEL to C-d via +`keyboard-translate'. The former functionality of C-h is available on +the F1 key. You should probably not use this setting if you don't +have both Backspace, Delete and F1 keys. + +Programmatically, you can call function +delete-key-deletes-forward-mode to toggle the behavior of the Delete +key. + ++++ +** C-u C-x = provides detailed information about the character at +point in a pop-up window. + ++++ +** Emacs can now support 'wheeled' mice (such as the MS IntelliMouse) +under XFree86. To enable this, use the `mouse-wheel-mode' command, or +customize the variable `mouse-wheel-mode'. + +The variables `mouse-wheel-follow-mouse' and `mouse-wheel-scroll-amount' +determine where and by how much buffers are scrolled. + ++++ +** Emacs' auto-save list files are now by default stored in a +sub-directory `.emacs.d/auto-save-list/' of the user's home directory. +(On MS-DOS, this subdirectory's name is `_emacs.d/auto-save.list/'.) +You can customize `auto-save-list-prefix' to change this location. + ++++ +** The function `getenv' is now callable interactively. + +** The many obsolete language `setup-...-environment' commands have +been removed -- use `set-language-environment'. + +++ ** The environment variable `EMACSLOCKDIR' is no longer used on MS-Windows.
