 - [bugfix:] Callbacks for non-repeating notifications were not called if they were not created in the current app instance on iOS.
 - [enhancement:] Added 'secondly' and 'minutely' as new repeat time aliases.
 - [bugfix:] `sound:null` didnt work for Android. The default sound was played.
+- [feature:] New interface `isScheduled` to check wether a notification with an ID is pending.
+- [feature:] New interface `getScheduledIds` to retrieve a list with all currently pending notifications.

+### isScheduled()
+Checks wether a notification with an ID is scheduled. It takes the ID as an argument and a callback function to be called with the result.
+```javascript
+window.plugin.notification.local.isScheduled(id, function (isScheduled) {
+
+});
+```
+
+### getScheduledIds()
+Checks wether a notification with an ID is scheduled. It takes a callback function to be called with the result as an array.
+```javascript
+window.plugin.notification.local.getScheduledIds(function (pendingIds) {
+
+});
+```
+
 ### getDefaults()
 Gives an overview about all available notification properties for the platform and their default values. The function returns an object.
