# Changes
## [1.0.0-beta.3] - 2019-05-04
### Added
* Add helper function for executing futures `test::block_fn()`
### Changed
* Extractor configuration could be registered with `App::data()`
or with `Resource::data()` #775
* Route data is unified with app data, `Route::data()` moved to resource
level to `Resource::data()`
* CORS handling without headers #702
* Allow to construct `Data` instances to avoid double `Arc` for `Send + Sync` types.
@ -14,6 +22,10 @@
* Fix `NormalizePath` middleware impl #806
### Deleted
* `App::data_factory()` is deleted.
## [1.0.0-beta.2] - 2019-04-24
