+* Caution! Backwards incompatible changes:
+  * As a message name, `-` now refers to the message on the standard input,
+    and not the the previous message anymore.  Use `.-` to refer to
+    the previous message in a short way.
+    The tools will print a warning if you use `-` and the standard input
+    comes from a TTY.
