** General Lisp changes:
-*** The escape sequence \s now stands for the SPACE character.
+*** New syntax: \s now stands for the SPACE character.
`?\s' is a new way to write the space character. You must make sure
it is not followed by a dash, since `?\s-...' indicates the "super"

`\s' stands for space in strings, too, but it is not really meant for
strings; it is easier and nicer just to write a space.
+*** New syntax: \uXXXX and \UXXXXXXXX specify Unicode code points in hex.
+
+For instance, you can use "\u0428" to specify a string consisting of
+CYRILLIC CAPITAL LETTER SHA, or `"U0001D6E2" to specify one consisting
+of MATHEMATICAL ITALIC CAPITAL ALPHA (the latter is greater than
+#xFFFF and thus needs the longer syntax).
+
+This syntax works for both character constants and strings.

*** The function `expt' handles negative exponents differently.
The value for `(expt A B)', if both A and B are integers and B is
negative, is now a float. For example: (expt 2 -2) => 0.25.
