This release is big. Until now, our automations and scripts have been very static. Starting today it should all be a bit more dynamic.

**Scripts** are now available in automations and when responding to Alexa/Amazon Echo. Both of these components will now expose data to be used in script templates (including `from_state` !). Passing data to script entities is available by passing the data to the script services.

```yaml
automation:
  trigger:
    platform: mqtt
    topic: some/notify/topic
  action:
    service: notify.notify
    data:
      message: {{ trigger.payload }}

automation 2:
  trigger:
    platform: state
    entity_id: light.hue
  action:
    service: notify.notify
    data:
      message: {{ trigger.to_state.name }} is now {{ trigger.to_state.state }}
```

**Entity Namespaces** allow you to influence the entity ids for a specific platform. For example you can turn `light.living_room` into `light.holiday_home_living_room` with the following config:

```yaml
light:
  platform: hue
  entity_namespace: holiday_home
```

### Deprecations
 - Conditions in automations should now specify which condition to use with `condition:` instead of `platform:`. For example `condition: state`.
 - RFXtrx has a new config format.

Old RFXtrx config format:

```yaml
  devices:
    123efab1:
      name: My DI.0 light device
      packetid: 1b2200000890efab1213f60
```

New RFXtrx config format:

```yaml
  devices:
    1b2200000890efab1213f60:
      name: My DI.0 light device
```
