Can Lambda automatically update layer configurations?

According to announcement "The AWS Lambda console now supports bulk update of layers", I was under the impression that "This release (would) eliminate(s) the need to update one function at a time or utilize an external script to perform the update on multiple functions."

I am currently using an external script to update multiple functions when lambda layers are updated. Is this notice implying an automatic way to update the layers? If so, how and where would I access this feature?

I am familiar with accessing the AWS Lambda console and manually bulk updating all functions that use that particular layer.

Any clarification would be appreciated! Thanks again!
