+*** The functions `find-charset-region' and `find-charset-string' include
+`eight-bit-control' and/or `eight-bit-graphic' in the returned list
+when it finds 8-bit characters.  Previously, it included `ascii' in a
+multibyte buffer and `unknown' in a unibyte buffer.
+
+*** The functions `set-buffer-modified', `string-as-multibyte' and
+`string-as-unibyte' change the byte sequence of a buffer if it
+contains a character from the `eight-bit-control' character set.
+
+*** The handling of multibyte sequences in a multibyte buffer is
+changed.  Previously, a byte sequence matching the pattern
+[\200-\237][\240-\377]+ was interpreted as a single character
+regardless of the length of the trailing bytes [\240-\377]+.  Thus, if
+the sequence was longer than what the leading byte indicated, the
+extra trailing bytes were ignored by Lisp functions.  Now such extra
+bytes are independent 8-bit characters belonging to the charset
+eight-bit-graphic.
+
+** Fontsets are now implemented using char-tables.
+
+A fontset can now be specified for for each independent character, for
+a group of characters or for a character set rather than just for a
+character set as previously.
+
+*** The arguments of the function `set-fontset-font' are changed.
+They are NAME, CHARACTER, FONTNAME, and optional FRAME.  The function
+modifies fontset NAME to use FONTNAME for CHARACTER.
+
+CHARACTER may be a cons (FROM . TO), where FROM and TO are non-generic
+characters.  In that case FONTNAME is used for all characters in the
+range FROM and TO (inclusive).  CHARACTER may be a charset.  In that
+case FONTNAME is used for all character in the charset.
+
+FONTNAME may be a cons (FAMILY . REGISTRY), where FAMILY is the family
+name of a font and REGSITRY is a registry name of a font.
+
+*** Variable x-charset-registry has been deleted.  The default charset
+registries of character sets are set in the default fontset
+"fontset-default".
+
+*** The function `create-fontset-from-fontset-spec' ignores the second
+argument STYLE-VARIANT.  It never creates style-variant fontsets.
+
+** The method of composing characters is changed.  Now character
+composition is done by a special text property `composition' in
+buffers and strings.
+
+*** Charset composition is deleted.  Emacs never creates a `composite
+character' which is an independent character with a unique character
+code.  Thus the following functions handling `composite characters'
+have been deleted: composite-char-component,
+composite-char-component-count, composite-char-composition-rule,
+composite-char-composition-rule and decompose-composite-char delete.
+The variables leading-code-composition and min-composite-char have
+also been deleted.
+
+*** Three more glyph reference points are added.  They can be used to
+specify a composition rule.  See the documentation of the variable
+`reference-point-alist' for more detail.
+
+*** The function `compose-region' takes new arguments COMPONENTS and
+MODIFICATION-FUNC.  With COMPONENTS, you can specify not only a
+composition rule but also characters to be composed.  Such characters
+may differ between buffer and string text.
+
+*** The function `compose-string' takes new arguments START, END,
+COMPONENTS, and MODIFICATION-FUNC.
+
+*** The function `compose-string' puts text property `composition'
+directly on the argument STRING instead of returning a new string.
+Likewise, the function `decompose-string' just removes text property
+`composition' from STRING.
+
+*** The new function `find-composition' returns information about
+a composition at a specified position in a buffer or a string.
+
+*** The function `decompose-composite-char' is now labeled as
+obsolete.
+
+** The new character set `mule-unicode-0100-24ff' is introduced for
+Unicode characters of the range U+0100..U+24FF.  Currently, this
+character set is not used.
+
+** The new character sets `japanese-jisx0213-1' and
+`japanese-jisx0213-2' are introduced for the new Japanese standard JIS
+X 0213 Plane 1 and Plane 2.
+
++++
+** The new character sets `eight-bit-control' and `eight-bit-graphic'
+are introduced for 8-bit characters in the ranges 0x80..0x9F and
+0xA0..0xFF repectively.
