+ * @brief abstract class for KNotification actions
+ *
+ * A KNotificationPlugin is responsible of notification presentation.
+ * You can subclass it to have your own presentation of a notification.
+ *
+ * You should reimplement the KNotificationPlugin::notify method to display the notification.
+ *
+ * Porting from KF5 to KF6:
+ *
+ * The signature of the virtual method
+ * KNotificationPlugin::notify(KNotification *notification, KNotifyConfig *)
+ * was changed to
+ * KNotificationPlugin::notify(KNotification *notification, const KNotifyConfig &).
+ *
+ * The signature of the virtual method
+ * KNotificationPlugin::update(KNotification *notification, KNotifyConfig *)
+ * was changed to
+ * KNotificationPlugin::update(KNotification *notification, const KNotifyConfig &).
