### New Features
+#### Improved Blueprints
+
+Significant work has gone into making YAML blueprints more powerful.
+The DSL is more expressive and a variety of new general-purpose entities,
+enrichers and policies have been written.
+
+New general-purpose constructs:
+
+* The `InvokeEffectorOnSensorChange` and
`InvokeEffectorOnCollectionSensorChange`
+ policies execute effectors on entities whenever a target sensor changes.
+* `ProxyEffector` forwards effector invocations from one entity to another.
+* `ConditionalEntity` creates an entity based on the truth of a config key
+ (e.g. `$brooklyn:scopeRoot().config("enable.loadBalancer")`).
+* `OnPublicNetworkEnricher` grants finer control of mapping public
+ and private network addresses to sensors.
+* `PercentageEnricher` publishes the ratio of two sensors.
+
+New blueprint DSL features:
+
+* `$brooklyn:entity` supports nested function calls,
+* `$brookln:getImmediately` resolves values immediately and throws if it
cannot,
