It will be released towards end of next week. You will see announcement here on geonet when it becomes public. In meantime, you can test this functionality using our next version.
Please take a look at this test app to see how globalIds are used with FeatureLayer.applyEdits. It is not the most intuitive app but will get the concept across.
To add a new features, click on the `Add Feature` button, then click on the map, change the severity value and provide a globalId for your new feature and finally click on the `Apply Edits` button.
To update an existing feature, click on a feature on the map, then change the severity value, click on the update feature button and finally click on the Apply Edits button.
I would like to point out that globalIds are supported for update and add operations for applyEdits. For delete operations you must use the objectIds. This will become available at 4.16.
Hope this makes sense,
