## 1.0
* `State` is now `Data`. You register Data during the App initialization process
and then access it from handlers either using a Data extractor or using
HttpRequest's api.
instead of
```rust
App.with_state(T)
```
use App's `data` method
```rust
App.new()
.data(T)
```
and either use the Data extractor within your handler
```rust
use actix_web::web::Data;
fn endpoint_handler(Data<T>)){
...
}
```
.. or access your Data element from the HttpRequest
```rust
fn endpoint_handler(req: HttpRequest) {
let data: Option<Data<T>> = req.app_data::<T>();
}
```
* AsyncResponder is deprecated.
instead of
```rust
use actix_web::AsyncResponder;
fn endpoint_handler(...) -> impl Future<Item=HttpResponse, Error=Error>{
...
.responder()
}
```
.. simply omit AsyncResponder and the corresponding responder() finish method
