* Changes in Emacs 21.4
+** calculator.el now has radix grouping mode. In this mode a
+separator character is used between every few digits, making it
+easier to indicate byte boundries etc. See the documentation of
+the `calculator-radix-grouping-mode' custom variable.
+
** You can now follow links by clicking Mouse-1 on the link.
Traditionally, Emacs uses a Mouse-1 click to set point and a Mouse-2
"checkout", "update" or "commit". That means using cvs diff options
-rBASE -rHEAD.
+** New variable `hs-set-up-overlay' allows customization of the overlay
+used to effect hiding for hideshow minor mode. Integration with isearch
+handles the overlay property `display' specially, preserving it during
+temporary overlay showing in the course of an isearch operation.

function used by the new `mouse-1-click-follows-link' functionality.
which means FUNNAME was previously defined as an autoload (before the
current file redefined it).

+** `load-history' now records (defun . FUNNAME) when a function is
+defined. For a variable, it records just the variable name.

** New Lisp library testcover.el works with edebug to help you determine
whether you've tested all your Lisp code. Function testcover-start
