0.2.0

Added

• AssetLocator class added to add / manipulate asset names and location
• Exception PathNotFound added.
• Added phpunit as require-dev dependency.
• Added CallbackStream which is copied from https://github.com/zendframework/zend-diactoros/blob/83e8d98b9915de76c659ce27d683c02a0f99fa90/src/CallbackStream.php
• Added https://github.com/http-interop/http-factory, so can work with any psr-7 implementations.
• Added Router class which can be configured with regx which can be injected to AssetAction if needed.
• Added Hkt\Psr7Asset\Container\AssetConfig class and removed the example class.
• Updated Readme

BC BREAK

• AssetService now accepts AssetLocator instead of array as first constructor argument
• Removed setRouteRegx method from AssetAction
• If file is not found, the 404 response is no longer send, delegates to next middleware or the final handler.
