I do want the new version. With the question, I was trying to see if I could get the lambda version to be the same as the package behind it so that if we ever roll back the Lambda we know which version of the package we're rolling back to.
For context, it's a lambda function using a docker image with a custom python package and its dependencies.
Typing this out now, might just try and add that package version as a tag to the lambda function instead
