+## 1.3 (2016-02-20)
+
+### Breaking Changes
+* The timeout arg to `serve` was replaced with a `Config` struct, which
+  currently only contains one field, but will be expanded in the future
+  to allow configuring serialization protocol, and other things.
+* `serve` was changed to be a default method on the generated `Service` traits,
+  and it was renamed `spawn_with_config`. A second `default fn` was added:
+  `spawn`, which takes no `Config` arg.
+
+### Other Changes
+* Expanded items will no longer generate unused warnings.
