• Fixed issue 1694 where tree-shaking was removing code related to background isolates and thereby preventing notification actions from firing. Readme has also been updated as applications will need to annotate functions invoked by the onDidReceiveBackgroundNotificationResponse callback with the @pragma('vm:entry-point') annotation as well. The example and docs have been updated to remove usages of the IsolateNameServer APIs due to issues in release builds. If anyone knows how to get these working then please submit a PR
