Upgrading Instructions for Yii Framework v2

!!!IMPORTANT!!!

The following upgrading instructions are cumulative. That is, if you want to upgrade from version A to version C and there is version B between A and C, you need to following the instructions for both A and B.

Upgrade from Yii 2.0 Beta

• If you used clearAll() or clearAllAssignments() of yii\rbac\DbManager, you should replace them with removeAll() and removeAllAssignments() respectively.

• If you created RBAC rule classes, you should modify their execute() method by adding $user as the first parameter: execute($user, $item, $params). The $user parameter represents the ID of the user currently being access checked. Previously, this is passed via $params['user'].

• If you override yii\grid\DataColumn::getDataCellValue() with visibility protected you have to change visibility to public as visibility of the base method has changed.

• If you have classes implementing yii\web\IdentityInterface (very common), you should modify the signature of findIdentityByAccessToken() as public static function findIdentityByAccessToken($token, $type = null). The new $type parameter will contain the type information about the access token. For example, if you use yii\filters\auth\HttpBearerAuth authentication method, the value of this parameter will be yii\filters\auth\HttpBearerAuth. This allows you to differentiate access tokens taken by different authentication methods.
