+### pub
+
+  * Running `pub run foo` within a package now runs the `foo` executable defined
+    by the `foo` package. The previous behavior ran `bin/foo`. This makes it
+    easy to run binaries in dependencies, for instance `pub run test`.
+
+  * On Mac and Linux, signals sent to `pub run` and forwarded to the child
+    command.
