+Changelog
+=========
+
+## v3.2 - 2021-06-01
+
+Omnipay 3.2 is compatible with PHP8. This is done by upgrading the test suite to PHPUnit 8/9, with the release of omnipay/tests v4 and omnipay/common v3.1. This change is primarily for gateway developers, to make it possible to actually test PHP8, but they will need to upgrade their tests to use PHPUnit 9 (the currently supported PHPUnit version). 
+## v3.1 - 2020-10-29
+
+Omnipay 3.1 uses Guzzle 7 by default (using the Guzzle 7 adapter). This doesn't change omnipay-common because they will work with any compatible Http Client.
+The minimum PHP versions is bumped to 7.2 because of this.
+
+## v3.0 - 2018-05-14
+
+Omnipay 3.0 focuses on separation of the HTTP Client, to be independent of Guzzle. 
+This release brings compatibility with the latest Symfony 3+4 and Laravel 5. 
+The breaking changes for applications using Omnipay are kept to a minimum.
+
+The `omnipay/omnipay` package name has been changed to `league/omnipay`
+
+### Upgrading applications from Omnipay 2.x to 3.x
+
+#### Breaking changes
+ - The `redirect()` method no calls `exit()` after sending the content. This is up to the developer now.
+ - An HTTP Client is required. Guzzle will be installed when using `league/omnipay`, 
+ but otherwise you need to required your own implementation (see [PHP HTTP Clients](http://docs.php-http.org/en/latest/clients.html))
+- The `omnipay/omnipay` package name has been changed to `league/omnipay` and no longers installs all the gateways directly.
+
+#### Added
+ - It is now possible to use `setAmountInteger(integer $value)` to set the amount in the base units of the currency.
+ - Support for [Money for PHP](http://moneyphp.org/) objects are added, by using `setMoney(Money $money)` the Amount and Currency are set.
+
+### Upgrading Gateways from 2.x to 3.x
+
+The primary difference is the HTTP Client. We are now using HTTPlug (http://httplug.io/) but rely on our own interface.
+
+### Breaking changes
+- Change typehint from Guzzle ClientInterface to `Omnipay\Common\Http\ClientInterface`
+- `$client->get('..')`/`$client->post('..')` etc are removed, you can call `$client->request('GET', '')`.
+- No need to call `$request->send()`, requests are sent directly.
+- Instead of `$client->createRequest(..)` you can create+send the request directly with `$client->request(..)`.
+- When sending a JSON body, convert the body to a string with `json_encode()` and set the correct Content-Type.
+- The response is a PSR-7 Response object. You can call `$response->getBody()->getContents()` to get the body as string.
+- `$response->json()` and `$response->xml()` are gone, but you can implement the logic directly.
+- An HTTP Client is no longer added by default by `omnipay/common`, but `league/omnipay` will add Guzzle. 
+Gateways should not rely on Guzzle or other clients directly.
+- `$body` should be a string (eg. `http_build_query($data)` or `json_encode($data)` instead of just `$data`).
+- The `$headers` parameters should be an `array` (not `null`, but can be empty)
+
+Examples:
+```php
+// V2 XML:
+ $response = $this->httpClient->post($this->endpoint, null, $data)->send();
+ $result = $httpResponse->xml();
+
+// V3 XML:
+ $response = $this->httpClient->request('POST', $this->endpoint, [], http_build_query($data));
+ $result = simplexml_load_string($httpResponse->getBody()->getContents());
+```
+
+```php
+// Example JSON request:
+
+ $response = $this->httpClient->request('POST', $this->endpoint, [
+     'Accept' => 'application/json',
+     'Content-Type' => 'application/json',
+ ], json_encode($data));
+ 
+ $result = json_decode($response->getBody()->getContents(), true);
+```
+
+#### Testing changes
+
+PHPUnit is upgraded to PHPUnit 6. Common issues:
+
+- `setExpectedException()` is removed
+
+```php
+// PHPUnit 5:
+$this->setExpectedException($class, $message);
+
+// PHPUnit 6:
+$this->expectException($class);
+$this->expectExceptionMessage($message);
+```
+
+- Tests that do not perform any assertions, will be marked as risky. This can be avoided by annotating them with ` @doesNotPerformAssertions`
+
+- You should remove the `Mockery\Adapter\Phpunit\TestListener` in phpunit.xml.dist
+
+
+## v2.0.0 - 2013-11-17
+
+### Package Separation
+
+As of 2.0, Omnipay has been split into separate packages. Core functionality is contained within the [omnipay/common](https://github.com/omnipay/common) repository, and all gateways have their own repositories. This means that if your project only requires on a single gateway, you can load it without installing all of the other gateways. All officially supported gateways can be found under the [Omnipay GitHub organization](//github.com/omnipay).
+
+If you want to install all gateways, you can still use the `omnipay/omnipay` metapackage in `composer.json`:
+
+~~~ javascript
+{
+    "require": {
+        "omnipay/omnipay": "~2.0"
+    }
+}
+~~~
+
+Alternatively, if you want to migrate to an individual gateway, simply change your `composer.json` file to reference the specific gateway (`omnipay/common` will be included for you automatically):
+
+~~~ javascript
+{
+    "require": {
+        "omnipay/paypal": "~2.0"
+    }
+}
+~~~
+
+### Breaking Changes
+
+The `GatewayFactory` class can no longer be called in a static fashion. To help those who want to use dependency injection, you can now create an instance of GatewayFactory:
+
+~~~ php
+$factory = new GatewayFactory();
+$gateway = $factory->create('PayPal_Express');
+~~~
+
+The following code is invalid and will no longer work:
+
+~~~ php
+$gateway = GatewayFactory::create('PayPal_Express'); // will cause PHP error!
+~~~
+
+If you want to continue to use static methods for simplicity, you can use the new Omnipay class:
+
+~~~ php
+// at the top of your PHP file
+use Omnipay\Omnipay;
+
+// further down when you need to create the gateway
+$gateway = Omnipay::create('PayPal_Express');
+~~~
+
+Behind the scenes, this will create a GatewayFactory instance for you and call the appropriate method on it.
+
+### Additions
+
+**Omnipay now supports sending line-item data to gateways.** Currently this is only supported by the PayPal gateway. Line item details can be added to a request like so:
+
+~~~ php
+$request->setItems(array(
+    array('name' => 'Food', 'quantity' => 1, 'price' => '40.00'),
+    array('name' => 'Drinks', 'quantity' => 2, 'price' => '6.00'),
+));
+~~~
+
+For more details, see the [pull request](https://github.com/omnipay/omnipay/pull/154).
+
+**Omnipay now also supports modifying request data before it is sent to the gateway.**. This allows you to send arbitrary custom data with a request, even if Omnipay doesn't support a parameter directly. To modify the request data, instead of calling `send()` directly on the request, you may use the new `sendData()` method:
+
+~~~ php
+// standard method - send default data
+$response = $request->send();
+
+// new method - get and send custom data
+$data = $request->getData();
+$data['customParameter'] = true;
+
+$response = $request->sendData($data);
+~~~
+
+For more details, see the [pull request](https://github.com/omnipay/omnipay/pull/162).

+## Incoming Notifications
+
+Some gateways (e.g. Cybersource, GoPay) offer HTTP notifications to inform the merchant about the completion (or, in
+general, status) of the payment. To assist with handling such notifications, the `acceptNotification()` method will
+extract the transaction reference and payment status from the HTTP request and return a generic `NotificationInterface`.
+
+```php
+$notification = $gateway->acceptNotification();
+
+$notification->getTransactionReference(); // A reference provided by the gateway to represent this transaction
+$notification->getTransactionStatus(); // Current status of the transaction, one of NotificationInterface::STATUS_*
+$notification->getMessage(); // Additional message, if any, provided by the gateway
+
+// update the status of the corresponding transaction in your database
+```
+
+**Note:** some earlier gateways used the `completeAuthorize` and `completePurchase` messages to handle the incoming
+notifications. These are being converted and the `complete*` messages deprecated.
+They won't be removed in OmniPay 2.x, but it is advisable to switch to the `acceptNotification` message when convenient.
+An example is Sage Pay Server [completeAuthorize](https://github.com/thephpleague/omnipay-sagepay/blob/master/src/ServerGateway.php#L81)
+which is now handled by [acceptNotification](https://github.com/thephpleague/omnipay-sagepay/blob/master/src/ServerGateway.php#L40).
