+## [19.3.0]
+
+* [Android][iOS][macOS] added `cancelAllPendingNotifications()` method for cancelling all pending notifications that have been scheduled. Thanks to the PR from [Kwon Tae Hyung](https://github.com/TaeBbong)
+
 ## [19.2.1]
 
 * [macOS] removed redundant code that was only applicable on macOS versions lower than 10.14. This should be a non-functional change since 18.0.0 bumped the minimum Flutter SDK requirements that in turn required macOS 10.14 at a minimum. Thanks to the PR from [Blin Qipa](https://github.com/bqubique)
