@section Old Lisp Features in Emacs 20
@itemize @bullet
-@item
-The function @code{bitmap-spec-p} has been renamed to
-@code{pixmap-spec-p} to encourage users to practice Emacs' help system
-while trying to find it.
-
@item
The @code{push} and @code{pop} macros are not defined.
+Neither are @code{dolist} and @code{dotimes}.
@item
You can't display images in buffers. (Emacs is meant for editing text.)
freely in Lisp programs, with no effects except what you implement for
yourself. With no images, who needs the @code{display} text property?
+@item
+The @code{field} text property has no special meaning; buffers are no
+longer subdivided into fields. (The division of information into
+fields is always rather arbitrary.)
+
@item
Faces have fewer attributes. The attributes @code{:family},
@code{:height}, @code{:width}, @code{:weight}, and @code{:slant},
have been replaced with a font name, a ``bold'' flag, and an
``italic'' flag.
-The attributes @code{:overline}, @code{:strike-through}
-and @code{:box} have been eliminated too.
+The attributes @code{:overline}, @code{:strike-through} and @code{:box}
+have been eliminated too. Underlining now always has the same color as
+the text---using any other color would be bad taste.
With fewer font attributes, there are no functions
@code{set-face-attribute} and @code{face-attribute}. Instead, you
were available in Emacs 21, but are not as useful there.)
@item
-There are no facilities for playing sound. This means Emacs will
-respect your peace and quiet, aside from occasional beeps.
+The standard faces @code{scroll-bar}, @code{menu}, @code{border},
+@code{cursor}, and @code{mouse} have been eliminated. They are rather
+strange, as faces, and therefore shouldn't really exist. You can use
+@code{set-border-color}, @code{set-cursor-color} and
+@code{set-mouse-color} to specify the colors for the frame border, the
+text cursor, and the mouse cursor. To specify menu colors, use X
+resources.
+
+@item
+Colors and other face attributes are no longer supported on character
+terminals, so you no longer have to worry about terminals making faces
+at you.
+
+@item
+Emacs will respect your peace and quiet, aside from occasional beeps,
+because there are no facilities for playing sounds.
+
+@item
+Emacs 20 provides a complex and badly designed method for handling
+character composition for languages such as Thai that display several
+letters as a single combined image. We are too ashamed of it to tell
+you any more than that.
+
+@item
+@code{delete-and-extract-region} has been deleted; instead, use
+@code{buffer-substring} to extract the text, then use
+@code{delete-region} to delete it.
@item
Regular expressions do not support the POSIX character classes
the scroll bars.
@item
-For simplicity, all ASCII characters now have the same height and width.
-(Certain characters, such as Chinese characters, always have have twice
+For simplicity, all @acronym{ASCII} characters now have the same height and width.
+(Certain characters, such as Chinese characters, always have twice
the standard width.) All characters are created equal.
+@item
+You can now resize any Emacs window, and size changes in one window can
+propagate to all others. Windows can no longer use
+@code{window-size-fixed} to get special privileges.
+
+@item
+The function @code{intern-soft} no longer accepts a symbol as argument.
+
+@item
+The function @code{bitmap-spec-p} has been renamed to
+@code{pixmap-spec-p} to encourage users to practice Emacs' help system
+while trying to find it.
+
@item
Tooltips operate using ordinary Emacs frames.
The functions @code{format} and @code{message} ignore and discard text
properties.
+@item
+The function @code{propertize} does not exist;
+you can get the job done using @code{set-text-properties}.
+
@item
Colors are supported only on window systems, not on text-only terminals.
So the support functions for colors on text-only terminals are
-not needed.
+not needed, and have been eliminated.
@item
The functions @code{color-values}, @code{color-defined-p} and
current buffer.
@item
-The function @code{assoc-delete-all} has itself been deleted.
+The function @code{assq-delete-all} has itself been deleted.
So there!
+@item
+The keyword @code{:set-after} no longer does anything in
+@code{defcustom}.
+
@item
The variable @code{small-temporary-file-directory} has no special
meaning. There's only one variable for specifying which directory to
variable, and some use the @code{TMPDIR} environment variable.
@item
-The variable @code{inhibit-modification-hooks}
+If the second argument of @code{save-some-buffers}, @var{pred}, is not
+@code{nil}, then the precise value no longer matters. Any
+non-@code{nil} value means the same as @code{t}: offer to save each
+non-file buffer that has a non-@code{nil} value for
+@code{buffer-offer-save}.
+
+@item
+The variable @code{inhibit-modification-hooks}
has no special meaning.

@code{file-attributes} returns the file size and the file inode number
only as a simple integer.
+Also @acronym{UID} and @acronym{GID} are always returned as integers.
