You can now select all or a subset of the functions that use a Lambda layer, and update them simultaneously to a newer layer version in the Lambda console.
Lambda layers provide a convenient way to package libraries and other dependencies that you can use with your Lambda functions. Using layers reduces the size of uploaded deployment archives and makes it faster to deploy your code. Previously, it was challenging to identify and update all the functions that used a specific layer version. With this release, the Lambda console displays a list of all the functions using a given layer and allows you to select multiple functions to be updated with a newer layer version. This release eliminates the need to update one function at a time or utilize an external script to perform the update on multiple functions.
This capability is available in the regions where AWS Lambda is available, with the exception of the Regions in China. For more information on availability, please see the AWS Region table.
