### 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
+ 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,
+* `$brookln:getImmediately` resolves values immediately and throws if it
+* `$brooklyn:object` supports parameterised constructors and static
factory methods, hugely increasing the range of objects that can be injected
+* `$brooklyn:entityId` returns the target entity's ID, and
+* `$brooklyn:self` accesses the resolving task's context entity.
+#### Bundled entities
+There have been many updates to the entities bundled with Brooklyn. In
+* `DynamicCluster` allows configuration of member removal strategies.
+* The `Transformer` enricher can be triggered by events on multiple
+* `ZooKeeperNode` publishes main.uri and `ZooKeeperEnsemble` aggregates
+ hosts and ports into comma-separated list under `zookeeper.endpoints`.
+* `BindDnsServer` listens on all interfaces and supports Centos and RHEL.
+* `NginxController` supports proxying with TLS client certificates.
+* `RiakNode` optionally configures security groups for intra-node
+ when supported by the target cloud.
+* `PostgreSqlNode` can be configured to grant [user
+* `SharedLocationSecurityGroupCustomizer` enables security group
+ configuration in yaml blueprints.
+* Feeds no longer poll if their entity is unmanaged.
+Several new test-case entities are introduced:
[supports](https://github.com/apache/brooklyn-server/pull/414) a greatly
expanded range of options.
+* `TestEndpointReachable` tests that a TCP endpoint can be reached.
+* `TestWinrmCommand` tests the success of commands in Windows instances.
+* `RelativeEntityTestCase` lets you write test cases that resolve their
target from another entity.
+Additionally, location customisers can now be attached to entities as
+initialisers, rather than having to dig into their `templateOptions`.
+#### Brooklyn server
+* The REST API requires CSRF headers for non-GET and HEAD requests when
+ sessions are in effect.
+ for details.
+* The catalogue scanner can be configured with whitelists and blacklists
+ of bundle IDs to control which bundles may present applications in the
+* The Karaf distribution includes equivalents of the
+ [cloud explorer
