The internal character representation
in
Emacs is no longer
Unicode-based; it is known as @code{emacs-mule}. This representation
can handle several different variants of the same character, each one
belonging to its own script. It marks each character with its script,
to better discern them from one another
.
The internal character representation
used by
Emacs is no
t
longer
based on Unicode. In this representation, called @code{emacs-mule},
each character belongs to one and only one script. Emacs makes no
attempt to distinguish between ``similar'' characters occurring in
different scripts
.
@item
The @code{functionp} function now returns @code{t} for special forms.
The @code{^} interactive spec code, the function
@code{handle-shift-selection}, and the variable
@code{this-command-keys-shift-translated} have all been removed.
Shift-translated keys are no longer treated specially, making Emacs'
handling of keybindings much more consistent.
@item
Temporarily-active regions are not created by giving the variable
@code{transient-mark-mode} values of the form @code{(only
. @var{oldvar})}. We instead use a more more complicated scheme:
setting @code{transient-mark-mode} to @code{only} enables Transient
Mark mode for the following command only, during which the value of
@code{transient-mark-mode} is set to @code{identity}; if it is still
@code{identity} at the end of the command, Transient Mark mode is
disabled.
@item
Many minibuffer functions, such as @code{read-file-name} and
@code{minibuffer-complete}, have been rewritten in C for greater
speed. The completion code has been considerably simplified; the
completion style can no longer be changed via
@code{completion-styles-alist}, and @code{completing-read} no longer
recognizes the special values @code{confirm-only} and
@code{confirm-after-completion} for its @var{require-match} argument.
@item
Emacs no longer supports explicitly-numbered groups in regular
expressions.
@item
The @code{^} interactive spec code has been removed, together with the
function @code{handle-shift-selection} and the variable
@code{this-command-keys-shift-translated}. Shift-translated keys are
no longer treated specially, making Emacs' handling of keybindings
that much more consistent.
The @code{permanent-local-hook} function property has no special
meaning.
@item
The @code{interactive-form} symbol property is no longer recognized.
The @code{functionp} function now returns @code{t} for special forms.
@item
The @code{interactive-form} symbol property has no special meaning.
Once you supply a function with an interactive form, the only way to
change it is to redefine the function.
@item
Emacs no longer creates temporarily-active regions by giving the
variable @code{transient-mark-mode} values of the form @code{(only
. @var{oldvar})}. Instead, it uses a more slightly more complicated
scheme: setting @code{transient-mark-mode} to @code{only} enables
Transient Mark mode for the following command only, during which the
value of @code{transient-mark-mode} is set to @code{identity}; if it
is still @code{identity} at the end of the command, Transient Mark
mode is disabled.
The @code{ignore-errors} macro has been moved into the @code{cl}
package.
@item
Many minibuffer functions, such as @code{read-file-name} and
@code{minibuffer-complete}, have been rewritten in C. The completion
code has been considerably simplified; for instance, the completion
style cannot be changed via @code{completion-styles-alist}, and
@code{completing-read} no longer recognizes the special values
@code{confirm-only} and @code{confirm-after-completion} for its
@var{require-match} argument.
Variables can now be both buffer-local and frame-local; buffer-local
bindings take precedence over frame-local bindings.
@item
Explicitly numbered groups in regular expressions are no longer
supported.
Faces can no longer be remapped.
@item
Faces can no longer be remapped.
Lisp programs now specify fonts by their names, which are strings
following the XLFD (X logical font descriptor) format. Fonts are no
longer represented using a special set of ``font'' data types. The
various functions that act on these data types, such as @code{fontp},
@code{font-spec}, and @code{list-fonts}, have all been deleted.
@item
Fonts are no longer represented using a special set of ``font'' data
types. Lisp programs may only specify fonts by name, as string
s
following the XLFD (X logical font descriptor) format
.
Emacs does not recognize the @code{FontBackend} X resource and the
@code{font-backend} frame parameter. On the X Window System, font
s
are always drawn using the X core font driver
.
@item
Display terminals are no longer represented using a ``terminal'' data
type
. This data type
is not necessary, because
Emacs can no longer
type
; this
is not necessary, because
we have removed the ability to
display on graphical and text-only terminals simultaneously. For the
same reason, the @code{window-system} variable is no longer
frame-local, and the @code{window-system} function has been removed.

@code{vertical-motion} can no longer be told to move to a specific

Emacs no longer recognizes the @code{permanent-local-hook} property of
local hook functions.
Windows no longer have parameters.
@item
The @code{ignore-errors} macro has been moved into the @code{cl}
package.
The @code{display-buffer} function has been rewritten in C. Its
window-splitting heuristics are a little less sophisticated, and a
little less documented. Window-splitting is handled internally,
instead of using @code{split-window-preferred-function} (which has
been removed). Windows are never split horizontally; the variable
@code{split-width-threshold} has been removed.
@item
The @code{mode-name} variable now accepts only string values, and
cannot take the form of a mode-line construct.
@item
Several keymap have been eliminated: @code{input-decode-map},
The behavior of @code{map-char-table} has changed. It calls the
mapping function for every single character in the table, instead of
using cons cells to represent contiguous character code ranges.
