- Moves where they appear up to the <App /> component.
- Instead of a <Notification /> wrapping component to move whatever you use for a notification up to where they need to appear (via ember-cli-flash), we now use a {{notification}} modifier now we have modifiers.
- Global notifications/flashes are no longer special styles of their own. You just use the {{notification}} modifier to hoist whatever component/element you want up to the top of the page. This means we can re-use our existing <Notice /> component for all our global UI notifications (this is the user visible change here)

# DataLoader
`<DataLoader />` works similarly to, and uses, `<DataSource />` but additionally
exposes various common states based on the status of the loading of the data.
These states are exposed as slots to enable you to easily render different
elements based on the state of the data.
Use the `@dataSource` decorator in your repositories to define URI to async
method mapping.
```javascript
class SomethingRepository extends Service {
@dataSource('/:partition/:nspace/:dc/services')
async youCouldCallItAnythingTodoWithGettingServices(params) {
console.log(params);
// {partition: "partition", nspace: "nspace", dc: "dc"}
return getTheThing(params);
}
}
```
```hbs preview-template
<DataLoader
@src="/partition/nspace/dc/services"
as |loader|>
<BlockSlot @name="loading">
Loading...
</BlockSlot>
<BlockSlot @name="error">
Error {{loader.error.status}}
</BlockSlot>
<BlockSlot @name="disconnected">
Whilst we could load the initial data, something happened subsequently that
meant we could load longer load updates to the data.
</BlockSlot>
<BlockSlot @name="loaded">
{{#each loader.data as |service|}}
{{service.Name}}<br />
{{/each}}
</BlockSlot>
</DataLoader>
```
