+** ChangeLog issues
+
+*** When you fix a bug, it can be helpful to put the bug number in the
+ChangeLog entry, for example:
+
+ * foo.el (foofunc): Fix the `foo' case. (Bug#123)
+
+Then the relevant bug can be found for easy reference. If it's an
+obvious fix (e.g. a typo), there's no need to clutter the log with the
+bug number.
+
+Similarly, when you close a bug, it can be helpful to include the
+relevant ChangeLog entry in the message to the bug tracker, so people
+can see eaxctly what the fix was.

+Activate `bug-reference-mode' in ChangeLogs to get clickable links to
