-    `is_assigned_char`, `textwidth`, `islower`, `isupper`, `isalpha`,
-    `isdigit`, `isxdigit`, `isnumber`, `isalnum`, `iscntrl`, `ispunct`, `isspace`,
-    `isprint`, `isgraph`, `lowercase`, `uppercase`, `titlecase`, `lcfirst` and `ucfirst`.
+  * `isnumber` has been renamed to `isnumeric` ([#25021]).
+
+  * `is_assigned_char` and `normalize_string` have been renamed to `isassigned` and
+    `normalize`, and moved to the new `Unicode` standard library module.
+    `graphemes` has also been moved to that module ([#25021]).
 
   * The functions `eigs` and `svds` have been moved to the `IterativeEigensolvers` standard
     library module ([#24714]).
 
   * `@printf` and `@sprintf` have been moved to the `Printf` standard library ([#23929],[#25056]).
