# Upgrade from 1.10 to 2.0

Version `2.x` is a complete rewrite of the existing code base. The public API has been trimmed down to a minimum.
The preferred way of using the SDK is through our "Static API" / global functions.

Here is a simple example to get started:

```php
\Sentry\init(['dsn' => '___PUBLIC_DSN___' ]);

\Sentry\configureScope(function (\Sentry\State\Scope $scope): void {
     $scope->setTag('page_locale', 'de-at');
     $scope->setUser(['email' => '[email protected]']);
     $scope->setLevel(\Sentry\Severity::warning());
     $scope->setExtra('character_name', 'Mighty Fighter');
});

// The following capture call will contain the data from the previous configured Scope
try {
    thisFunctionThrows(); // -> throw new \Exception('foo bar');
} catch (\Exception $exception) {
    \Sentry\captureException($exception);
}

\Sentry\addBreadcrumb(new Breadcrumb(Breadcrumb::LEVEL_ERROR, Breadcrumb::TYPE_ERROR, 'error_reporting', 'Message'));
```

The call to `\Sentry\init()` sets up global exception/error handlers and any uncaught error will be sent to Sentry.
Version `>= 2.0` conforms to the [Unified SDK API](https://docs.sentry.io/development/sdk-dev/unified-api/).
It has a fundamentally different concept, it's no longer recommended to just use a `Client` unless you really know what you are doing.

Please visit [our docs](https://docs.sentry.io/error-reporting/quickstart/?platform=php) to get a full overview.

### Misc

- All the classes have been renamed and moved around to follow the PSR-4
  convention and `final` have been added where appropriate.

  library you are required to use [Composer](https://getcomposer.org/).

- The `Raven_Util` class has been removed.

### Client

- The constructor of the `Client` (before `Raven_Client`) class has changed its signature and
  now requires to be passed a configuration object, an instance of a transport
  and an event factory.

  Before:

  ```php
  public function __construct($options_or_dsn = null, $options = array())
  {
      // ...
  }
  ```

  After:

  ```php
  public function __construct(Options $options, TransportInterface $transport, EventFactoryInterface $eventFactory)
  {
      // ...
  }
  ```
  
 The suggested way to create your own instance of the client is to use the provided builder (`ClientBuilder`) that will take care of instantiating a few dependencies like the PSR-7 factories and the HTTP client.

  and `Raven_ErrorHandler::registerShutdownFunction` have been removed. You should
  use the `ErrorHandler::register` method instead, but note that it registers all

  removing the `$isError` and `$vars` arguments and it has been marked as `internal`

  replacement for it.

- The method `Raven_ErrorHandler::shouldCaptureFatalError` has been removed and
  there is no replacement for it.

### Serializers

  {
      // ...
  }
  ```

  After:

  ```php
  public function __construct(int $maxDepth = 3, ?string $mbDetectOrder = null, int $messageLimit = Client::MESSAGE_MAX_LENGTH_LIMIT)
  {
      // ...
  }
  ```

- The `Raven_ReprSerializer` class has been renamed to `RepresentationSerializer`
  and its constructor changed signature.

  Before:

  ```php
  public function __construct($mb_detect_order = null, $message_limit = null)

  }
  ```

  After:

  ```php
  public function __construct(int $maxDepth = 3, ?string $mbDetectOrder = null, int $messageLimit = Client::MESSAGE_MAX_LENGTH_LIMIT)
  {
      // ...
  }
  ```
