+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

+for both A and B.
+
+Upgrade from Yii 2.0.7
+----------------------
+
+* Minimal required version of the [swiftmailer/swiftmailer](https://github.com/swiftmailer/swiftmailer) library has been raised to 6.0.0.
+  You should adjust your program according to the [change list](https://github.com/swiftmailer/swiftmailer/blob/v6.0.0/CHANGES#L4-L17) for this version.
+
+* Since `Swift_MailTransport` has been removed in SwiftMailer 6.0.0, this extension now uses `Swift_SendmailTransport` by default.
+
+* Minimum version of PHP has been raised to 7.0.
